ABSTRACT
The article presents the findings of an instrumental survey of a 14 kW cogeneration (CHP) plant. CHP-14 complies with the city needs for heat and electric power, and ensures the continuity and quality of the power supply. Thermal power is generated by eight power generating units through recuperation of heat coming from the high-temperature cooling circuit of the hot-gas reciprocating engine and the exhaust heat, for which each GPU is equipped with plate-type heat-exchangers and a waste-heat boiler. Due to the missing unit-by-unit heat energy metering, an instrumental survey of the heat utilization systems at CHP-14 was carried out, to calculate the heat generation, heat losses into the environment through non-insulated pipelines of waste-heat boilers, and to define the specific heat rate for CHP power and heat generation. The instrumental survey was carried out under four load conditions - at 30 %, 50 %, 70 % and 85 %.
