Authors: Ullah M Usman
Published: September 2022

Pakistan and China have been enjoying multilayered ties. They have mutual cooperation and a supportive environment for each other. Their relationship has strengthened after the 2000s. They shifted their ties according to the global shadow. However, with the passage of time, their relationship transformed from Geo-economic to Geo-strategic. 2015 was the turning year of their ties with signing the C.P.E.C. project cost of $46Billion U.S. dollars. Both countries inked the agreement when the president of China, Xi Jinping, visited Pakistan in 2015. They are trying to safeguard their interests against the animosity of the U.S. and India. The pivot policy of the U.S. contains China's influence over the region. India is, on the other hand, sees it as a threat to its security.In this article, we are going to explore the ties between China and Pakistan and will observe the response of India and the U.S. towards them.

Authors: Gar Ruqayya Aminu , Umar Mohammed Nuru
Published: September 2022

Infrastructure comprising road and rail network, health care, and educational facilities have powerful effects on the overall electoral process of people in various political entities. They also play a determining role in setting the bases of the voting choice and change in the orientations of the people towards their political system. Reports on infrastructure in Bauchi state exist but are incomplete to academic principles. This study examines infrastructure deterioration and the outcome of the 2019 gubernatorial elections in Bauchi state Nigeria through a qualitative method of data collection and analysis. Findings of the e study concludes that, part of the underlying principle for the success of an opposition political party, the Peoples Democratic Party (PDP) in the 2019 gubernatorial elections includes. The electorates’ assessments of the All Progressives Congress (APC) administration’s discouraging records in the provision and maintenance of Infrastructure comprising: road and rail network, health care system, and educational facilities. Better election campaign strategy and reliable contestant offered by opposition parties; and enhanced training by the electoral body, the Independent National Electoral Commission (INEC). This confirms the significance of Infrastructure (road and rail network, health care, and educational facilities) as crucial factors influencing electoral outcomes of the 2019 gubernatorial elections in Bauchi state, Nigeria.
De kracht van het paard als co-therapeut
Authors: Nagtegaal Chantal
Published: September 2022

Het behandelaanbod binnen de GGZ is vooral gericht op ons cognitief vermogen terwijl bekend is dat het cognitief vermogen van mensen met psychiatrische problematiek verminderd is. Het is ook aangetoond dat de gemiddelde persoon 20% onthoud van wat hij hoort en 90% onthoud van ervaringen. Equitherapie is een behandelmethode die gebruikt maakt van ervaringsgericht leren, een behandeling met een paard als co-therapeut. Een paard als co-therapeut doet aanspraak op o.a. mogelijkheden, kwetsbaarheden en kracht en legt de focus op het lichamelijke en emotionele aspect door de non-verbale interactie. Onderzoek wijst uit dat de inzet van paarden een significante vermindering geeft van PTSS, sociale angst, prikkelbaarheid, beperkingen door emotionele problemen, etc. en versterkt mentale veerkracht, vitaliteit en het sociaal functioneren. Veelal leidt de inzet van paarden als co-therapeut ook tot betere en snellere resultaten ten opzichte van therapieën zonder paard. De getrainde ggz-professional maakt vervolgens tijdens de sessies met het paard o.a. gebruik van bekende tools zoals ACT en neemt de veiligheid van mens en paard in acht. Equitherapie is, ondanks dat het nog niet evidence-based is, een wetenschappelijk veelbelovend en passend behandelaanbod binnen de GGZ: Equitherapie biedt niet alleen aansluiting bij de mensen die bij ons aankloppen voor hulp maar sluit ook aan bij de kwaliteitsstandaarden én bij de huidige maatschappelijke ontwikkelingen om mens en natuur meer samen te brengen.
Selected aspects of document forgery in the context of Article 5 of the Constitution of the Republic of Poland
Authors: Semków Dorota
Published: September 2022

One of the tasks of the state specified in Article 5 of the Constitution of the Republic of Poland of 2 April 1997 is to ensure security of its citizens. The aim of the study is to show a relationship between crimes against document credibility listed in Chapter XIX of the Penal Code and the security of citizens. The main con­clusion resulting from the analysis of the selected topic was that forgery of travel documents is a significant factor threatening citizen safety. The above results from the fact that documents very often serve as both an object and a tool in many crimes. Therefore, they constitute an activity of a preparatory nature before commit­ting further criminal acts, as well as a way of hiding traces of other crimes. It should be emphasized that the use of false documents, and thus their introduction into legal circulation, means that a person illegally using such documents legally acquires many rights.
Joseph Ratzinger’s Apologia for the Concept of the Soul
Authors: Borto Paweł
Published: September 2022

This article aims to show the rationale behind Joseph Ratzinger’s defence of the concept of the soul in his theological reflection. Since Ratzinger did not produce a separate text justifying the need to maintain the concept of the soul yet justified it when discussing other issues, primarily those related to the Christian profession of faith, a distinction was made between biblical and philosophical-theological arguments to analyse his thought. The analysis indicated that J. Ratzinger saw two fundamental paths in the biblical tradition leading to the formation of the concept of the soul. The first is that which discovers God as the Life-Giver more powerful than death. The second involves the maturing of the profession of faith in the resurrection and the fact of Christ’s resurrection. The concept of the soul, to be developed later, will be based on these two fundamental truths attested to by the Bible and will be the drawing of anthropological conclusions originating in the most important truths of the faith, such as the resurrection of the body or belief in the Last Judgement. Ratzinger also examines other statements of the Church’s Magisterium or those handed down by philosophical and theological tradition from this standpoint. Hence, for him, the concept of the soul does not so much belong to particular anthropology as it derives from a profession of faith that calls for a clear and simple message that is not confined to the expert considerations of theologians.
Human Soul in the Light of Czesław Stanisław Bartnik’s Universalistic Personalism
Authors: Miczyński Jan
Published: September 2022

The article presents a contemporary understanding of the human soul according to Czesław Stanisław Bartnik (1929–2020), the founder of universalistic personalism. The term “soul” has been understood in many different ways throughout the history of human thought, hence it still raises confusion today. It is sometimes dismissed as too “religious” and replaced by the word “ego” or “person.” It seems that a successful attempt to link the history of human thought with a contemporary understanding of the person is Bartnik’s personalistic system. The article groups Bartnik’s thoughts on the “human soul” into four main blocks: personalistic reflection on the history of the concept of “soul”; place of the soul in the structure of the contemporary person (real being); clarification of the significance of the soul’s “function” in the inner and outer world of an individual; the existence of a “social person” and – in a sense – a “social soul” i.e., the spiritual self-awareness of society (although there is no single common soul for all people). The analysis leads to the following conclusions: the terms “soul” and “person” are not synonymous today; the meaning of “person” is broader than that of “soul,” however, the “person” does not displace the “soul.” Putting it positively, the soul together with the body constitutes human nature, and thanks to this nature, there is a metaphysical personal “self” (ontic ego) which can be described as a “spiritual soul” or “spirit” (whereby the metaphysical “self” is inseparable from the “soul”) Man as a person expresses himself through body and soul, as well as the metaphysical self (which is present in the consciousness). Because of its “spiritual soul,” a person is constantly in development, transcends reality and is moving towards its ultimate fulfilment in the Communion of the Divine Persons. This is done by making the right moral choices, in conjunction with the Person of Jesus Christ.

Socio-philosophical Approach to the Problem of Human Subjectivity
Authors: Momdzhyan Karen Kh.
Published: September 2022

The author analyzes the phenomenon of the subject in its socio-philosophical perspective, which differs from the ontological, gnoseological, and anthropological consideration of subjectivity. Using the methodology of the substantive-activity approach, the author considers the subject as an active entity capable of initiating and controlling goal-oriented activity aimed at satisfying his own needs, interests, and goals. The author is convinced that the properties of the social subject - the ability to self-purpose existence, based on the motivational examination of different options of behavior and the free choice between them - have only separately taken people, human individuals. The author criticizes the ideas of "methodological collectivism," which attributes subjectivity to society, the state, and other institutional forms of human coexistence that influence activity but are not capable of carrying it out. The article analyzes organizational forms of subject-object mediation based on links of intersubjectivity, compositional intersection, and interpenetration. The author offers his understanding of the well-known philosophical formulas: "there is no activity without a subject and no subject outside of activity"; "there is no activity without an object and no object outside of activity"; "there is no subject without an object". The author considers subjectivity as the most important property of man, which is preserved by him in the conditions of forced functioning, which presupposes normally interiorization of externally imposed goals and agreement to their realization. At the same time, a person is capable of losing his or her subjective status in a situation when external coercion deprives him or her of the freedom of choice - when it is not a person who does something, but something is done to a person, using another person's activity as an object.
Derzhavin and the Return of the Victorious Tsar
Authors: Klein Joachim
Published: September 2022

This article is about Derzhavin’s ode on Alexander I’s return to Russia after his victory over Napoleon. It aims to shed light on the development of Derzhavin’s panegyric poetry and thereby also on the cult of the Russian emperor. One point deserves special attention: the sacralization of the tsar. I argue that in contrast to the tradition of Russian panegyrics, Derzhavin’s ode represents Alexander not only as a successful ruler and a military hero, but also as a very pious Christian, one could even say: as a saint, which was highly unusual in Russia’s 18th and early 19th century. We shall also see how Derzhavin uses a panegyric motif borrowed from Lomonosov: the infinite space of the Russian fatherland. Finally, the article attempts to situate Derzhavin’s occasional poem in its “place in life” (“Sitz im Leben”), focussing on the specific, including the biographical circumstances under which it was created and in which it was to function. Two concluding digressions will deal with the demonization of Napoleon and the idea of human greatness in the early years of the 19th century.
Folklore and Reproach: The Experience of Sentiment Analysis Based on Constructions
Authors: Shmurak Roman
Published: September 2022

This article presents a pilot experiment to identify reproach in folklore material. The theoretical core of the work is the idea that reproach, like all linguistic phenomena, should have formal expression in language. From which it follows that reproach can be identified in the text on the basis of its formal characteristics, relying on the tools of construction grammar, and not only with the help of semantics and context. Concrete examples demonstrate the effectiveness of the method, its reliability and evidence-based nature in comparison with approaches based on context and pragmalinguistic content. Thus, the study faced two tasks.
Firstly, it presents the experiment to conduct sentiment analysis in the absence of any academic corpus of folklore texts at the time of writing the article. Although the volume of fundamental editions of folklore texts is more than significant, the natural absence of specialized lexical and grammatical tagging in such texts, which allows creating corpus queries that are heterogeneous in structure, returns a researcher to manual processing of folklore material without hope of automating the procedure. At the same time, the existence of recognized electronic texts allows you to make accurate queries using the interface of programs for editing and reading documents in PDF and DJVU formats.
Secondly, the method of identifying reproach on the basis of constructions and the results of using this method in the form of concrete examples of the reproach in folklore texts are demonstrated. The advantages and disadvantages of working with precise queries in interfaces of PDF-Xchange and DJVU-reader programs are analyzed. The analysis of the obtained results is proposed, as well as the “bottlenecks&8j1; and prospects of such research are discussed.
Language Game with a Case Ending -ов or How Padonki Were Replaced by Kittens
Authors: Dobrushina Ekaterina R.
Published: September 2022

The article discusses the non-standard use of the endings of nouns for feminine and neuter words (продавать рыбов), which became popular in the Runet language in 2021. The competition of the zero ending with -ов in the genitive and animate accusative, arising in the Old Russian language as a result of mixing two declensions, in the modern language led to the victory of -ов (нет столов, домов), while maintaining the zero ending for some groups (нет англичан, мальчишек) and variation in colloquial speech for a number of words (нет помидоров/помидор), meanwhile the zero option in the XXI century is clearly less common than the “ов-forms”. Under the influence of a “viral” meme about a conversation between cats and a seller, since the summer of 2021, a language game has become widespread, consisting in intentionally joining of -ов to the “unsuitable” stem: рыбов, книгов, деньгов, etc. Such a language game has existed for a long time (for example, the traditional ironic imitation of the colloquial делов-то), but as rare individual jokes, and in 2021 it became frequent, popular, used in a variety of memes and in advertising, associated with the theme of “kittens” and a certain worldview. The “Language of kittens” began to turn into a new linguoculturological phenomenon, comparable in degree of recognition to the Olbanian, or the Padonkaffsky jargon, the peak of popularity of which occurred in the mid-2000s. Now, instead of the misrepresentation of the orthographic appearance of the word (аффтар), which is characteristic of the Olbanian, referring to the idea of protest, the grammatical form is changing, referring to the idea of quiet touching humility before the injustice of life.

Published: September 2022

Mantis shrimp is one of the marine organisms that has a very abundant diversity of species. The similarity of morphology of this group make it difficult to identify morphologically. Therefore, identification was carried out using a DNA barcoding approach. The purpose of this study was to identify the mantis shrimp species from Manokwari waters using molecular techniques. The CO1 gene fragments were amplified by using LCO and HCO primers. The DNA sequences obtained were analyzed for homology, phylogeny, and genetic distance using MEGA X software. A total of 537 base pairs of CO1 gene fragments of mantis shrimp from Manokwari were obtained. The results of the homology analysis on GenBank, show the highest similarity of 91.18% with sequences from the genus Gonodactylus. Analysis of phylogenetic tree and genetic distance showed the same results and supported each other with homology analysis on GenBank data.

Introduction: The dissemination and adoption of healthy eating habits are crucial in promoting Public Health. Metabolic syndrome increases the risk of developing diabetes and cardiovascular disease, a leading cause of death. Viral hepatitis causes a high morbidity burden and a high incidence of hepatocellular carcinoma.Objective: This case-control aims to investigate the impact of eating habits, especially functional food, on biomarkers of Metabolic Syndrome, Hepatitis B/C. The bibliographic lack of research on this matter was the impetus for this study.Methods: 90 (aged> 18 years) patients participated in the study, equally distributed in the three diseases and 90 healthy controls. The cardiovascular-hepatic biomarkers evaluated were: HbΑ1c, CHOL, TG, HDL, SGOT, SGPT, ΝΤ-proBNP, U, and CR.Results: The main groups of conventional and selected functional foods were recorded through their frequency of consumption and their effect on biomarkers (Statistically significant level, p-value <0.05). BNP was statistically significantly correlated (<300 pg./ml) with the consumption of wine, legumes, and honey, Urea with the consumption of fruits, Cr with the consumption of nuts and olive oil, and Cholesterol with the consumption of honey and herbs. Increased consumption of nuts was statistically significantly correlated with the improvement of BNP and U-values, vegetables with the improvement of SGPT, coffee fruits, and herbs with the improvement of SGOT values.Conclusion: Our results agree with the international references, where the beneficial effects of functional foods are mainly captured descriptively and not in absolute values of biomarkers, as we have tried to highlight in our case-report study. Although in a small sample, the results highlight the beneficial effect of functional foods on cardiovascular-hepatic biomarkers. More prospective studies are needed for clearer results.Keywords: Functional Food; Metabolic Syndrome; Hepatitis B; Hepatitis C; Biomarkers

Authors: Li Pengfei , Lin Zeyuan , Zhou Zhiyong , Li Yanli
Published: September 2022

With the gradual integration of large wind farms, the wind power penetration in power system is gradually increasing. Since different wind turbines access grid may have different effects on the system, it is necessary to study the effect of different wind turbines access grid on the system transient stability. This paper makes a comparative study on the system stability of constant speed wind turbine (CSWT) and the doubly-fed induction generator (DFIG) after grid-connected. Firstly, we present the dynamic models of CSWT and DFIG. Then, we use IEEE 3-machine 9-bus system to study the effect of CSWT and DFIG connected to the system on the system transient stability under different wind power penetration. Simulation results show that with the increase of wind power penetration, the transient stability of the system shows a trend of increasing first and then decreasing. However, DFIG will deteriorate the system transient stability as wind power penetration increases.

Published: September 2022

The new round of power reform, energy internet and new generation digital technology has greatly promoted the development of integrated energy services. In order to develop a specialization integrated energy services plan, it is necessary to make a portrait of business scenes. Firstly, a set of indicator system is established, and typical daily load curves are extracted using Piecewise Aggregate Approximation method and Symbolic Aggregation Approximation method to calculate indicators to obtain the data base. Secondly, the clustering results of eight basic scenes are obtained using K-means cluster analysis method, namely, single-peak type which can participate in demand response, single-peak type which cannot participate in demand response), double-peak type which can participate in demand response, double-peak type which cannot participate in demand response, post-single-peak type and continuous power consumption type. Finally, integrated energy services solutions are proposed for the six business scenes respectively. The results show that the power consumption characteristics of each business scenes are very different, and it is necessary to develop specialization integrated energy service solutions for different scenes.

Published: September 2022

The accurate forecast of wellbore temperature and pressure during intervention operations is critical to the long-term exploitation of deep-water oil and gas resources. A wellbore temperature prediction model was constructed in the seawater and formation sections based on Hasan and Kerber’s gas-liquid two-phase flow heat transfer model and integrated with the features of intervention operations. Simultaneously, the heat exchange produced by the change in fluid flow rate caused by the tool placement was evaluated. The wellbore pressure prediction model is developed in the intervention tool and intervention operation sections, and the friction gradient is modified by introducing the intervention operation.The established temperature and pressure model is coupled and solved iteratively, and the disturbance law of the wellbore temperature and pressure field induced by the intervention operation is investigated. The results show that the pressure in the wellbore gradually decreases when the tool is removed; the temperature at the mudline of the wellbore with high gas production is higher, and the wellhead pressure is low; the tool size is weakly sensitive to the wellbore; and the wellbore temperature and pressure are weakly sensitive to the running speed. The aforesaid findings have some guiding relevance for the design of the intervention operation plan, as well as the prediction and prevention of hydrate in the wellbore during deep-water gas well cleaning and blowout.
Research on Carbon Emission in Liaoning Province Based on Kaya Identity
Authors: Yan Tingting , Ding Benzhe , Wang Hui
Published: September 2022

For studying the role of energy structure change in carbon intensity in Liaoning Province, this paper uses the modified model of Kaya identity and the carbon intensity factor decomposition model of industrial and energy construction to calculate the contribution of energy structure to carbon intensity change elements and reveal the causes of carbon intensity factors in Liaoning Province. The carbon intensity factor is also affected by the total energy consumption, economic development, industrial structure, population and technological advancement. Therefore, the ridge regression model is established to further clarify the direct, indirect and total effects of the carbon intensity factor of energy construction, and the path analysis is made. According to the outcomes, the direct inhibitory role of energy structure in reducing carbon intensity is relatively small, which is mainly reflected in the indirect inhibitory effect of elements including economic development, industrial structure, technical advancement and population; The proportion of coal and primary power consumption is the main driving force for the decline of carbon intensity, while the proportion of oil and natural gas consumption and energy intensity inhibit it.
Numerical Simulation of Shear Failure Behavior of Hydrate-Bearing Sediment Using Discrete Element Method
Authors: Nie Shuaishuai , Chen Chen , Song Jian
Published: September 2022

Gas recovery from hydrate-bearing sediments attracts worldwide interest due to the huge reserves of methane there, recognized as a promising future energy resource. However, the mechanical behavior of hydrate-bearing sediment is rarely studied. In this study, the drained shear test on hydrate-bearing sand with different hydrate saturation was simulated using the discrete element method. In particular, the pore habits of hydrate in sands were considered in the simulation, and the meso-failure behavior such as the evolution of contact-force chains and the occurrence of microcracks were thoroughly investigated. In general, the simulations yielded the mechanical response (e.g., deviatoric stress-strain curve) of hydrate-bearing sand similar to the laboratory experiments, and the existence of hydrates plays a crucial role in the failure behavior. It is found that “X-type” shear bands are more likely to form in hydrate-bearing sand with higher hydrate saturation because enough bonds are broken to facilitate microcrack connection. Furthermore, tensile failure, tensile-shear failure, and compression-shear failure exist simultaneously during shearing, of which tensile failure and tensile-shear failure are dominant.

Published: September 2022

With the emission of a large number of greenhouse gases, global warming has become the focus of attention. In this paper, structural path analysis (SPA) and environmental extended input-output analysis (EEIOA) are used to study the carbon emission of various sectors in Guangdong Province. The proportion of carbon emission in different sectors is analyzed from different final demand, and the key carbon emission sectors and key carbon emission paths are determined. The results show that HEA sector (heavy industry sector) and ELE sector (electric power sector) are the key carbon emission sectors in Guangdong Province, accounting for 30.7% and 17.1% of total carbon emission, respectively. Export is the final demand for carbon emission in Guangdong, accounting for 66.7%. Most of the carbon emission paths of export are relatively short, tending to direct carbon emission, and most of the end points of the paths are HEA sector (heavy industry sector) and LIG sector (light industry sector). Most of the carbon emission paths of consumption mainly flow into consumption with SER sector (service sector) and ELE sector (electric power sector) as the end points. Most of the carbon emission paths of investment are more than two sectors, and most of the carbon emission of the paths flow into investment with CON sector (construction industry) as the end point, while CON sector (construction industry) causes carbon emission inflows from other sectors, so a large number of indirect carbon emission caused by investment.

Published: September 2022

Shale gas fracturing flowback fluid is produced during shale gas exploitation, and its complex composition and high chloride content result in limited efficiency of conventional technology. In this work, the Co-TiO2 nanotube array (Co-TiO2 NTAs) electrode with high chlorine evolution activity was successfully prepared by electrodeposition for the treatment of containing chlorine PAM simulated wastewater. The internal morphology, crystal structure, and electrochemical characteristics of the nanotubes were analyzed by scanning electron microscopy, X-ray diffraction, energy dispersive spectrometry, and linear sweep voltammetry. The electrochemical catalytic oxidation activity toward chlorine evolution reaction and degradation against polyacrylamide (PAM) in chlorine-containing wastewater were investigated. The results demonstrated that the chlorine evolution potential of the TiO2 NTAs electrode was decreased after loading 0.0333 mg/cm2 of cobalt by bipolar pulse electrodeposition. The results showed that the removal rate of chemical oxygen demand (CODcr) was 62.7% and the yield of active chlorine (ACl) was 45.2 mg/L after 1 hour of electrolysis, which were attributed to the excellent catalytic performance of the novel electrodes for the degradation of polyacrylamide. Combined with the characterization results of GC-MS and IR, the degradation mechanism of PAM was briefly described. The results indicated that the novel Co-TiO2 NTAs electrodes have a broad application prospect in electrochemical oxidation-catalytic degradation of high chlorine containing wastewater.
Study on Adolescent Pro-Environmental Behaviors from the Perspective of Intergenerational Transmission
Authors: Liu Haoqiang

Pro-environmental behaviors (PEBs) are that a people make efforts to minimize his negative impacts due to damage to nature by protecting and improving the environment. Pro-environmental behaviors become more and more important, especially for adolescents. Since adolescents are the future of our country, and they will make the environmental policy that will lead to human sustainable development. Adolescence is an important period for behavioral changes, especially pro-environmental behaviors changes. Families, especially parental expectations and behaviors, play a central role in educating and passing on pro-environmental behaviors from one generation to another generation. In this article, we first defined pro-environmental behaviors. Second, we explored psychosocial determinants of adolescent pro-environmental behaviors. We then elaborated on the psychological mechanisms underlying adolescent pro-environmental behaviors. Finally, we proposed intervention strategies for adolescent pro-environmental behaviors.

Published: September 2022

Through core CT analysis and cyclic reaction simulation experiment, the filling characteristics of structural fractures are analyzed, and the filling mechanism of fractures is revealed in this paper. The results show that the fracture filling degree has obvious inverse correlation with the length, maximum opening, absolute fracture linear density, and inclination of fractures, which indicates that the fractures with poor connectivity are more likely to be filled. Within the fracture networks, the mineral filling degree is controlled by the flow speed and overflow. When the fluid from deep underground flows through the fracture system with poor connectivity, its flow velocity is relatively slow, and the environment is relatively stable, which leads to the mineral components in saturated solution are easier to precipitate and deposit in fractures. When the fracture connectivity is very poor and the overflow flow is low, the fracture filling degree will be reduced accordingly. The research results of fracture filling have guiding significance for the prediction of fracture permeability distribution.

Authors: Li Chen
Published: September 2022

In this paper, the fine/turbo software of NUMECA was used. Based on the three-dimensional steady Reynolds averaged N-S equations, the S-A turbulence model was used to calculate the relationship between tip clearance and diameter of the impeller, which were δ = 0.1%, 0.3%, 0.5% and 0.7% respectively. The clearance flows of four water jet axial flow pumps with different tip clearances were numerically studied at different flow rates. The results indicate that the size of the clearance affects the cavitation performance of the blades, the efficiency and head of the pump, and has a great impact on the performance of the pump. It provides a useful exploration for the design improvement of axial-flow waterjet pump.

Study on Material Corrosion Resistance of Flue Gas Waste Heat Exchanger
Authors: Han Tingting
Published: September 2022

According to the statistics of China Electricity Council, about 97% of China’s coal-fired power generating units adopted wet desulfurization process (WFGD), of which the limestone-gypsum wet desulfurization process is the main process, accounting for about 91% of coal generating units. Without GGH, chimney exports can form white smoke plume. To solve the problem of environmental protection of white smoke plume and boiler flue gas waste heat recovery, the heat exchanger will be applied in flue gas condensation. But, the SO2, CO2, HCl and other complex components in flue gas can lead to equipment serious corrosion, so, it is necessary to study the heat exchanger and chimney material’s corrosion resistance. In this paper, the natural corrosion experiments in the actual chimney condensate of 2205 duplex stainless steel, 2507 super duplex stainless steel, 316L austenitic stainless steel and TA2 materials were studied by hanging weight loss method and electrochemical method at different temperatures. The results show that: The existence of weld in stainless steel and TA2 will increase the corrosion tendency and corrosion rate of the material. In static immersion, the higher the temperature, the higher the corrosion rate; Corrosion rate is 2507<2205< TA2< 316L; In the presence of SO42- and F-, the oxide film of TA2 is destroyed and its corrosion resistance is reduced, which provides a certain reference for material selection of heat exchangers and chimneys.
