Published: October 2020

Abstract
With the slowdown of external economic growth, more stringent review of investment execution, and in-depth promotion and implementation of transmission and distribution price reform, the implementation of lean management of state grid investment has been accelerated. The improvement of lean management level of 10kV projects, which account for more than half of the investment in power grid infrastructure, plays a greater role in promoting the overall investment efficiency of power grid. The lean management of power grid investment emphasizes “scientific decision making before investment - precise implementation in the event - scientific evaluation after the event”. From the perspective of investment lean management - strengthening the precise implementation in the matter, this paper takes the power grid infrastructure projects of 10kV and below as the research object, through combing the management key points and relevant management requirements of key nodes in the whole process, from the aspects of compliance, rationality and effectiveness of investment execution, this paper sorts out and determines the investment execution analysis indicators and evaluation rules, which provides the basis for the next step of investment execution index scenario application, and also provides support for comprehensively improving the lean management level of investment in 10kV and below power grid infrastructure projects.

Authors: Qiao Shuang , Wang Pan , Bai Yang 
Published: October 2020

Abstract
Since the 21st century, global clean energy governance has developed rapidly and gradually attracted the attention of scholars at home and abroad as an emerging field. The development and utilization of the global Clean energy Governance Network has greatly promoted the development of social productive forces, promoted economic globalization and scientific and technological progress, deepened the interdependence of energy and economy among countries around the world, and consolidated the foundation of cooperation among them. At present, the global clean energy governance presents a state of “disorder” with multiple mechanisms superimposed on each other, and is faced with many governance difficulties and dilemmas. By building a global clean energy governance network model, this paper tries to solve the stability and balance of multiple participants in the governance network. On the basis of win-win cooperation, countries should clarify their responsibilities and obligations and work together to promote clean energy governance. We should accelerate the transformation and upgrading of the global energy mix and explore a path of green, clean, low-carbon, environmentally friendly, healthy and sustainable energy cooperation.

Authors: Wu Jie , Zhu Hanhua , Hu Yiming 
Published: October 2020

Abstract
With regard to the oil characteristics of volatility and fluidity, safety issues may occur in case of oil tank leakage, conflagration and even explosion. In this thesis, the fire dynamics simulator (FDS for short) was used to simulate the conflagration of a 5000m3floating-roof oil tank. By simulating and calculating the oil tank conflagration, it obtained the effect of the distribution principle and the ambient wind speed in the thermal radiation field on the distribution principle in the radiant heat field. In comparison of the heat flux failure criteria at home and abroad, the safe intensity threshold between adjacent oil tanks was analyzed when the conflagration occurs on single oil tank. Then it came to a conclusion that, latent risk exists in current domestic fire separation distance 0.4D, which couldn’t meet the safety requirement on adjacent oil tanks. Meanwhile, it analyzed the distribution principle of the radiation thermal field in single floating-roof oil tank conflagration, and obtained the minimum safety distance of adjacent oil tanks at various ambient wind speeds, thus providing reference standards and scientific proof for designing safe tank farm as well as controlling the danger sources.

Authors: Mingyou Zhong , Bo Zhang , Leixiang Bian , Xiaoli Rong , Chenli Cui , Jiayang Li , Songtong Han 
Published: October 2020

Abstract
The layered ground under the excitation of a harmonic magnetic field will generate a secondary magnetic field. On the condition of low induction number, the apparent conductivity can be obtained by using the normalized secondary field measured by the instrument directly. By discretizing the integral of relative response function density, the expression of contribution value of conductivity of each layer to the apparent conductivity can be obtained. By using multiple sets of transceiver distance, we can obtain different apparent conductivity observation equations, then the conductivity and thickness of each layer can be solved by Gauss-Newton method. A three-layer medium model containing a V-shaped tunnel is designed for inversion simulation calculations. The results show that the higher the SNR of observed signal, the more stable the inversion result. The maximum relative error of thickness is about 10%.

Abstract
The coal storage yard of thermal power plants are exposed to the air, causing problems like polluting the environment, falling short of requirements of eco-protection and undermining safe production. It causes threats in three forms:coal dust, coal pile explosion, and coal pile spontaneous combustion. Wind and dust suppression walls, dry coal sheds, fully enclosed coal sheds and other measures can be used in these yards to prevent pollution in the yard. Pollution treatment in these yards can avoid static dusting of coal and reduce the spread of dynamic dusting. This study interpreted the necessity of environmental treatment of coal storage yards and the development of three main technologies, and conducted detailed analysis and discussion of various environmental treatment solutions for coal storage yards of thermal power plants. This study intends to provide experience and lessons for environmental treatment of coal storage yards.
Research on temperature and humidity decoupling control of clean air conditioning system
Authors: Huang Cuicui , Zhao Yulei 
Published: October 2020

Abstract
In the clean air conditioning system, in order to ensure that the temperature and humidity in the room are within the allowable accuracy range, it is necessary to control the dew point temperature. However, due to the inconsistency of the temperature and humidity control systems, the delay and inertia time constant of each channel are very different, so the dew point temperature is difficult to control. In order to achieve accurate control, multiple valves are opened at the same time in the system, which leads to energy loss, and usually a single circuit works normally. But when multiple chains work at the same time, the system is not easy to be stable. Therefore, in order to ensure the long-term safe operation of multi-parameter control system, making full use of mature technology and single variable control experience is an effective method to manage multi-parameter system.
Review on landfill leachate treatment methods
Authors: Anqi Tu , Zhang Zhiyong , Suhua Hao , Xia Li 
Published: October 2020

Abstract
In most countries, sanitary landfill is the most commonly used method to eliminate municipal and industrial solid waste, but landfill produces seriously polluted landfill leachate. Landfill leachate contains many kinds of pollutants: such as refractory organic compounds and heavy metals. In general, there are three methods to treat landfill leachate: leachate transfer, biological processes, chemical and physical methods and membrane processes. Membrane processes can be divided into four types: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). Membrane process has the advantages of stable effluent and high rejection rate for refractory organic matter. But high treatment cost and membrane fouling problem affect the applications of membrane in practice.

Authors: Yue Yang , Wang Yanxiang 
Published: October 2020

Abstract
Glass fiber reinforced concrete (GFRC) is a very widely used material. However, the highly alkaline environment in concrete will erode and destroy the glass fiber therein, so it is particularly important to improve the corrosion resistance of glass. In this study, ZrO2 and TiO2 were introduced into the La2O3-CaO-Al2O3-P2O5 system glass and their effects on the structure and properties of the glass were systematically studied. The results show that the introduction of ZrO2 and TiO2 has a similar effect on rare earth doped glass. For one thing, it will increase the density of the glass and make the structure of the glass dense. For another, it can improve the water resistance and alkali corrosion resistance of the glass. SEM images showed that after the glass was immersed in the alkali solution, a protective CaO film was formed on the surface of the glass sample. As the etching time increases, the protective film on the glass surface peels off in a sheet shape, and the skeleton of the glass peels off in a lump shape.

Published: October 2020

Abstract
The Early Cambrian Qiongzhusi Formation on the southern margin of the Sichuan Basin (Southern China) has experienced a long geological process. High degree of thermal evolution of the organic matter shows a great impact on the organic evolution, reservoir microscopic pore types and structure characteristics in this formation. In this study, we investigate the major types and structural features of microscopic pores in shale gas reservoirs of the Qiongzhusi FM. Different types of matrix pores are found, over-mature shale gas reservoirs in the Qiongzhusi FM. mainly have well-developed micropores, but their average specific surface area (SSA) and pore volume are smaller than those in the Longmaxi Formation. The degree of thermal evolution poses the greatest impact on microscopic pore structure, which is significantly positively correlated with SSA and pore volume; however, when exceeding this range, SSA and pore volume both drastically decrease with increasing degree of thermal evolution. Compared with those in the Longmaxi FM., microscopic pores of shale gas reservoirs in the Qiongzhusi FM. feature pore- SSA and large surface porosity. The better the development of micropores, the larger the SSA and Vp of shales, which are more conducive to shale gas adsorption and accumulation.

Authors: Wang Yaron , Wang Peirong 
Published: October 2020

Abstract
Through long-term production practice and theoretical research, the basic law of heat transfer process is summarized. In the process of stable heat transfer, the heat transfer is directly proportional to the temperature difference between cold and hot fluids and is proportional to the heat transfer area. The heat transfer is also directly proportional to the heat transfer process’s intensity, that is, the heat transfer coefficient. According to the shape of the partition wall, the heat transfer calculation can be divided into flat wall heat transfer and cylinder wall heat transfer. The heat transfer calculation of cylinder wall is complex, and different calculation standards will get different results.

Published: October 2020

Abstract
It has become the need of our society to use municipal solid waste (MSW) under the vision of waste-to-energy (WTE) strategy in order to utilise MSW and to address the energy issues over the world. With respect to the energy, refused derived fuel (RDF) is the energy source of MSW, whose reliability and quality is analysed in this work. The energy content and combustion characteristics of RDFs in oxygen-enriched environment are explored. Three different RDFs (RDF-A, RDF-B and RDF-C) had been adopted from three different waste materials. Plastics, wood and cloth are the major constituents in the recipe of taken RDFs. Proximate and ultimate analysis, thermo gravimetric analysis and calorific value tests had been performed for all RDF samples. The results showed that the RDF-A contains high amount of carbon (52.44%) and hydrogen (4.184%) content and good calorific value (5278 k.cal/kg), which leads to a better fuel quality. TGA analysis revealed that with the increase in the volatile matter fraction of RDFs, the retention time under combustion atmosphere has also been increased accordingly. By analysing of all results, RDF-A was suggested to be the best for energy applications and can be used as fuel for various combustion reactions.

Published: October 2020

Abstract
In this study, a novel deep eutectic solvent (DES) triethylamine/salicylic acid was synthesized and was used for the extractive denitrogenation of model oil. The structure of the DES was analyzed by fourier transform infrared spectrometry and the factors that influence nitrogen removal efficiency were investigated. Under the conditons of 20 min time, 30 °C temperature, 800 rpm stirring speed, 1:1 mass ratio of DES to oil, nitrogen removal efficiency reached more than 95%. After two extraction stages the nitrogen content of model oil could be reduced to less than 10 ppm. Therefore, the novel DES triethylamine/salicylic acid will became a promising extractant for fuel oil denitrogenation.
