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 operation efficiency of a gas engine by avoiding the occurrence of the situation getting impossible to continue heating operation since the heating operation must be stopped in a short time after starting the heating operation. SOLUTION: Hot water temperature of a temperature stratified state in a hot water storage tank 3 when stopping the heating operation is detected by temperature sensors 31 to 35. Upper limit temperature (55 °C) of hot water capable of cooling cooling water by heat exchange heat in an exhaust heat heat exchanger 22 supplied with the cooling water of the gas engine 1 as a heat source is used as reference temperature. Effective predicting heat quantity capable of accumulating heat up to the reference temperature is arithmetically operated on the basis of detecting hot water temperature information and capacity information of respective layers of A1 to A5. An operation starting condition of the heating operation is set so that an effective predicting heat quantity arithmetic operation value becomes larger than a determining heat quantity value of setting a heat quantity value capable of accumulating heat when performing the heating operation by operating only for a lower limit operation duration (one hour) required from operation efficiency of the gas engine.
