The article discusses a way to increase the efficiency of automobile operation by improving methods for ensuring the operability of electrical equipment based on the diagnosis of generators by output voltage. As a diagnosis, it is proposed to perform a spectral analysis of the generated voltage in idle mode and to determine the state of various generator elements from the results. The effectiveness of the proposed solutions is determined by the non-separable diagnostics of the generator, which, based on a thorough examination, can determine the state of various elements of the generator. This method does not require taking the generator out of operation, does not depend on its design and can be used in difficult operating conditions to obtain preliminary information about the state of the generator at the initial stage of maintenance.

This article discusses some of the practical application of cavitation technologies in autonomous heating systems, attached elementary economic calculation. The modern achievements and cavitation vortex heat generators, principle of operation and types of such equipment. Marked positive and negative aspects of installation and operation of heat generators. A comparative analysis of the economic calculation of seasonal operating costs of the vortex heater as auxiliary heating systems and district heating tariffs for Pavlodar.

Different diagrams of thermal pumps operation at thermal power plants are considered in the article. Thus, installation diagrams are considered for thermal pump based on the use of low -grade heat of turbo-unit lubricating system oil and blow-down water of a steam generator.

One of the agent modern tasks is to ensure the cleanliness of the air basin. To ensure this, it is necessary to clean the combustion products of the fuel removed from the boilers after their cooling into the atmosphere from harmful substances, including nitrogen oxide.
