The work is devoted to the study of the boiling process of multicomponent working fluids (MWF) used in refrigeration and cryogenic engineering. The description of the method of determination of heat transfer coefficient during boiling of zeotropic mixtures in horizontal heated channel is given as well as the design of the experimental stand allowing to make such measurements. This stand is designed on the basis of a refrigeration unit operating on the JouleThomson throttle cycle and allows to measure the heat transfer coefficient with an error not exceeding 15 %. Knowing of the heat transfer coefficient will be very useful in the design of heat exchangers for refrigeration machines operating on a mixed refrigerant.

The article presents the statistics of false alarms of automatic frequency unloading devices for 2012-2016. An analysis of the types of automatic frequency unloading devices operated in the Kuzbass power system is also presented. As a result of the analysis it was established that the main reason for the false triggering of the automatic frequency unloading is the absence of a lock in the speed of the frequency reduction or its incorrect setting. To prevent false triggering of the automatic frequency unloading in the event of run-out of the motor load, organizational and technical measures are proposed. It is noted that the correct setting of the blocking for the rate of frequency reduction requires the participation of all entities of the electric power system (System Operator, network organizations, consumers). Comparison of the existing devices by functional and the presence of locks from rate of change of frequency is made. Also, scientific and technical problems are formulated, the solution of which is necessary to prevent false triggering of the automatic frequency unloading when the electric motors run out.

In the article the prospects of using local solid fuel as an energy resource at the objects of small distributed generation is analyzed. The estimation of coal supply of Russian regions is carried out. Coal reserves for each of the regions are reduced to the unitary parameters - per head of the population, area and gross regional product which allowed a comparative assessment with the identification of regions where the location of low-capacity power plant is preferable.

The method for calculating the temperature-humidity mode of brick and reinforced concrete chimneys is presented. The processes of heat exchange of combustion products in the gas volume of the chimneys and heat and mass transfer in it’s walls also, are modeled. The parameters of vapour transfer in the walls of reinforced concrete chimneys in various operating modes of the boiler plant are calculated. The range of flue gases parameters at which the "dry" operating mode of a reinforced concrete chimneys is realized is determined.

This article outlines one of the possible ways to solve the problem by applying composite brushes with heightened resource on TED for municipal electric and locomotives by using reneizlechimoj part of the brushes.

The actual problem of increasing the efficiency of energy storage devices based on multi-element lithium-ion batteries is considered. The purpose and functions of a battery monitoring and control system that monitors the parameters and controls the charging and balancing process and improves the performance of the drive are considered. Practical application of the technique of searching for the optimal ratio of the charge time and the number of charging / balancing cycles has been made.

The temperature of the housing of LED lamps is determined under different conditions of their operation in lighting devices. It is shown that the creation of ventilation holes in the plafond or in the system of its fastening allows to lower the body temperature of LED lamps by 1025% and thereby significantly increase the service life.

The conditions of operation of the main and auxiliary equipment of TPPs essentially depend on the quality of fuel oil. The article considers the problem of improving the combustion process of fuel oil and associate produced by burning of sulfur oxides due to the introduction of additives. A part of the duct of the boiler is simulated up to the burners, where the additive particles are introduced. Areas of entrainment of particles in the duct of the boiler are investigated for uniform addition of the additive.

The particles driftin closed tuberesonator by the influence of viscous drag force using CFD package was considered. On the left bound of resonator gas velocity oscillates harmonically at the first resonant frequency. The four vortices of Schlichting in boundary layer and four vortices of Rayleigh were shown. The particles by the influence of its own drift and acoustic flow accumulate on the ends of the tube. Maximum particle drift near the boundary between vortices was observed. Comparison of the results with other author results shows satisfactory accuracy.

The method of local fluctuations offered earlier is applied to its realization. This method allows to describe and assign analytically in computer calculations the structure of the medium filled with inclusions. On the basis of the  turbulent flow with more simple laminar flow with fluctuations, simulating the «vortex backfill». The calculated model of «vortex backfill» is constructed, allowing to calculate and analyze turbulent flow in pipes.
