摘要：The schema for gas engine waste heat recovery to electrical power by dual circuit power generation unit with different working agents has been developed. The method and the most efficient power generation unit heat mode calculation algorithm under the conditions of the given restrictions on the temperature differences in the heat exchangers has been developed. Based on the mathematical modeling of heat modes it has been stated that 4200 kW of heat power can be utilized to generate 520 kW of electrical power for JMS 620 gas engine. It has been calculated that the efficiency of secondary heat recovery to electrical power reaches 12.3 % which leads general efficiency increase for a gas engine from 42.9 up to 50.0 %.
