The article gives a mathematical description of heat transfer processes in all the heating elements, ranging from automatic gas water heater and ending on the residential areas. At the same time takes into account the major sources of heat, and possible ways of its dissipation. The result is a block diagram of a developed dynamic model of the heating system, which, together with the structure of the automatic control device can serve as a basic tool for the analysis and synthesis of the complex automated system.

The modeling of complex systems, radiant heat transfer in anthropogenically disturbed the atmosphere, solar electric and thermal power plantsare considered. The structural diagram of the simulation of solar radiation on the tributaries heat perceptive surface and solar thermal power plants is discussed. Calculations of the spectral intensities and flux of solar radiation are carried out taking into account the selectivity of the molecular absorption of the ingredients of the radiation of the gas phase of the atmosphere, scattering and absorption of radiation by atmospheric aerosols and clouds in view statistics of their distribution according to the station's location and time of year.

Facilities of laser remote sensing as an effective method of lidar-based environmental monitoring of the thermal power plants’ air basin are considered. Principles of lidar monitoring systems development are described. Features of description and processing of the laser sensing echo-signals obtained from the industrial areas’ air are reviewed. Outlooks of using the contactless lidar-based method to solve the environmental problems are discussed.

The paper describes new engineering solutions when developing a test bench for studying experimental models of reciprocating electrical machines, as well as the hardware-software control system. A crank mechanism was used when developing the bench to create hydraulically driven reciprocating motion. The designed hardware-software system allows for controlling the bench and the test subject due to a large number of inputs and outputs of various applications. The sensors integrated into the bench allow for constructing the complete picture of the test and receiving a sufficient amount of high-precision data. The high flexibility of the bench and the test subject control algorithm allows for conducting a wide range of various tests of electrical products.

Stochastic calculation model of heat recovery steam generator (HRSG) reliability measures value determination are described in the article. Analysis of metal thermo-stress state of heating surface and analysis of material properties are underlying of method. Failure-free operation is estimated by the non-exceedance condition of working stress over the limit value. Influence of design characteristic of HRSG on failure-free operation is explored in the article. The suggested method is available for parameter optimization of combined cycle gas turbine (CCGT) power plants in Power Supply System and for selecting configuration of CCGT.

The paradoxical domain of nonexistence or double solution for the problem on definition of the motion of elliptical pendulum with registration the empirical dry Coulomb friction law is being investigated in this paper. It has been revealed that the parametric condition this domain definition has the mechanical meaning, which does agree with static friction low for the slider of pendulum.

The method of technical performance estimation of Gas Turbine with variable Power Turbine nozzle geometry is described in the paper. The method is based on the processing of the engine characteristics provided by producer. Approximations are given for power and efficiency calculations of the gas turbine type GTK-25I(R). Appropriate model verification according to test data of real engines on site is also presented.

The article focuses on the gases cleaning various methods from the dispersed phase, that adversely affects on the holding of technological processes. The design and scheme of the drying gas separator from condensed moisture and the method of its calculation are presented. The dependence of the energy complex of the gas velocity for different nozzles, which shows that the best is to use nozzles "Inzhekhim-2000" with a surface nozzle area of 800 m2 / m3 . The separation efficiency calculations of water drops from a natural gasbearing strata gazasenomanskaya and oil aerosol ethylene –coolagents in this unit is calculated. Combined separator ensures high efficiency of the separator removal of the liquid phase (98-99%), larger than 3 microns and oil aerosol – more than 1 m. Thus, a combined separator has a relatively small geometrical dimensions. The device has a low hydrodynamic resistance, thereby energy costs for its operation are reduced.

Results of experimental investigation of heat-exchange liquid and solid components introduced (in the model materials), formed at thermal opening of the fuel elements on the inclined surface of the vibrotransporter. It was recommended, that when parameters of vibration provided the movement of the solidified particles the required heat-transfer coefficient depends primarily on the frequency of fall drops monotonically increasing with its increase, and to a lesser on the vibration parameters and cleanliness of heat-exchange surface. Receiving results recommended for calculations cooling surface of the liquid and solid components at thermal autopsy of the fuel elements.
