Description
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions

Description
We have considered hybrid nontraditional and renewable sources of energy in terms of optimizing their work based on the knowledge of technical and functional peculiarities of each. We used classification of clusters of nontraditional and renewable energy of sources, depending on the proportion of replacing power in energy consumption and on the type of nontraditional and renewable energy of sources. We examined a simulation model of the hybrid cluster using the structural diagram and performed statement of the problem by means of the full and multifactor experiment. We applied the method of analysis of non-stationary random process disturbing influences

Description
The article presents methods of industrial tests of the of technical device utility model designed for boilers E-1,0-0,9G-3 QL-500, D-721 of small and medium capacity. The research is aimed at improving the efficiency of fuel combustion in the boiler furnaces due to uniform distribution of airflow when supplying it to the boiler burner
