摘要： PROBLEM TO BE SOLVED: To eliminate any waste in heat recovery and improve the efficiency thereof by minimizing unnecessary heating by an auxiliary heat source. SOLUTION: A fixed time after a thermal on-off valve is opened to start to supply and circulate heating water, a quantity of supplied heat necessary for heating to a set temperature is computed according to the temperature of the heating water, set heating and a flow rate in a heating circulating circuit. A determination is next made whether the quantity of supplied heat can be covered by a quantity of generated heat in a gas engine corresponding to a quantity of recovered heat from waste heat of the gas engine or not. If such coverage is impossible, heating of the heating water by the auxiliary heat source is started.

摘要： PROBLEM TO BE SOLVED: To improve the total heat efficiency without dissipating useless heat. SOLUTION: Waste heat from a gas engine 1 is recovered in a first heat exchanger 5, and when there is no need of supplying it to a heating load 2, a hot medium from the gas engine 1 is bypassed from the first heat exchanger 5 through a first bypass piping 7 to eliminate useless heat dissipation in the first heat exchanger 5. Further, a flow rate of the hot medium flowing through a second heat exchanger 12 is controlled to be mixed with a hot medium flowing through a second bypass piping 14, whereby return temperature of the hot medium to the gas engine 1 is lowered for prevention of supercooling.
