Abstract

The paper considers relevance of the issue of development of all sectors of the national economy, including such an important industry as agriculture. The development of the agricultural industry is associated in some cases with some of its specific features, which involve the necessity (sometimes historically developed) to have autonomous and remote objects of agricultural production. At the same time, production facilities and housing of service specialists are forced to be located at some distance from the sources of central (or main) electricity and heat supply.

To achieve the stated objective of this study, it is necessary to estimate the building's (consumer's) heat loss, which will be equal to the heat required for its heating. This required analyzing the heat balance data for the planned engine-generator system and the possibility of recovering secondary heat from the engine-generator in the exhaust gas, coolant, and oil recovery system, taking into account its simultaneous generation of electrical energy.

Based on the experimental heat balance data presented in the technical literature, it was found that the value generated from secondary heat in the engine-generator recovery system depends on the amount of electrical energy generated for the same consumer.

Based on the analysis, specific conclusions are made for the implementation of cogeneration plants at various facilities, both for investors and for manufacturers of cogeneration plants based on internal combustion engines.
