Title: Способ работы котельной установки
Inventor: KUDINOV ANATOLIJ ALEKSANDROVICH
IPC: F22B33/18
Filed: 2020-03-24
Granted: 2021-03-01
Abstract: Изобретение относится к области теплоэнергетики и может быть использовано в котельных установках, работающих на природном газе. Для повышения экономичности котельной установки, работающей на природном газе, общий поток уходящих продуктов сгорания котельной установки разделяют на три потока, один из которых направляют в существующий основной газоход, а два других потока подают в дополнительные газоходы, которые располагают параллельно существующему основному газоходу, при этом в каждом дополнительном газоходе для охлаждения продуктов сгорания ниже точки росы водяных паров до температуры 38-42°С располагают по одному конденсационному поверхностному теплообменнику. В первом теплообменнике производят предварительный подогрев дутьевого воздуха до температуры 20-30°С перед подачей его в воздухоподогреватель котла, а во втором производят подогрев до температуры 35-40°С атмосферного воздуха перед подачей его в котельный цех на отопление. Кроме того, в расчетном режиме работы котельной установки при температуре наружного воздуха (-28)-(-32)°С, равной средней температуре наиболее холодной пятидневки, в существующий основной газоход направляют 30-35% уходящих продуктов сгорания. В первый дополнительный газоход подают 25-30%, а во второй дополнительный газоход - 45-35% уходящих продуктов сгорания от их общего потока. Для повышения температуры продуктов сгорания, охлажденных ниже точки росы водяных паров в конденсационных поверхностных теплообменниках, осуществляют смешение трех потоков в основном газоходе перед дымососом и суммарный поток продуктов сгорания при температуре 70-75°С, превышающей точку росы водяных паров 45-48°С на 25-27°С, отводят в атмосферу. Это позволяет повысить экономичность котельной установки. 1 ил.

Abstract: FIELD: physics.  
     SUBSTANCE: invention is used to study the structure and properties of diamagnetic substances by nuclear magnetic resonance spectroscopy. The essence of the invention lies in the fact that the method of obtaining a two-dimensional correlation spectrum of chemical shifts of NMR signals with high resolution is based on spontaneous coherent mixing of spins of any pairs of magnetic nuclei with spin 1/2 in an ultraweak magnetic field. To obtain such a two-dimensional spectrum, the stages of preparation, evolution, and detection are carried out in a strong magnetic field of an NMR spectrometer, and coherent mixing of the spins of nuclei with different gyromagnetic ratios under the action of scalar interaction between these nuclei occurs spontaneously, under conditions of strong coupling between these nuclei in an ultra-weak field, in as a result of nonadiabatic switching of the magnetic field strength from strong to ultraweak. 
     EFFECT: invention is aimed at providing possibility of obtaining a two-dimensional high-resolution NMR spectrum, which gives a complete map of the correlations of chemical shifts of NMR signals for any pairs of magnetic nuclei with spin 1/2 with a different gyromagnetic ratio in the composition of an individual substance and thus revealing signals from an individual compound in the complex NMR spectrum of a multicomponent system of various substances.

Abstract: FIELD: electric power industry. 
     SUBSTANCE: invention relates to the electric power industry and can be used to determine the location of damage on power transmission lines or networks, in particular, for remote determination of the coordinates of the place of occurrence of a corona discharge on a high-voltage power line. Two radiometers are placed at a stationary observation post. The optical system of the first narrow-field radiometer forms a field of view, one that's narrow in the vertical direction and wider in the horizontal direction. The optical system of the additional radiometer forms another field of view, narrow in the horizontal direction and extended one in the vertical direction. Then the geographical coordinates of the location of the stationary post with radiometers and of the supports of the high-voltage power line section are to be determined and fixed. Moving the field of view of the additional radiometer along a rectilinear trajectory within all the wires on the section of the high-voltage power transmission line to be monitored, the angular position of its optical axis is fixed, on which the radiometer registers a signal indicating the presence of radiation. The geographic coordinates of the projection onto the horizontal plane of the radiation source are calculated. The field of view of the first radiometer is moved within the angular size in the vertical plane of the field of view of the additional radiometer. The angular position of the optical axis of the first radiometer is recorded, on which it registers a signal indicating the presence of radiation. The height of the radiation source is calculated. The geographic coordinates and the relative height of the radiation source are displayed. The operations are repeated sequentially until the end of the section of the high-voltage power transmission line to be controlled. 
     EFFECT: increased efficiency in determining the coordinates of the place of occurrence of corona discharge on an extended section of a high-voltage power transmission line.
