摘要： PROBLEM TO BE SOLVED: To enhance the recovering efficiency of heat emitted from an engine. SOLUTION: Cooling part 6A of the engine 2 and an exhaust gas heat exchanger 9 utilizing the exhaust gas from the engine 2 are furnished with a circulating passage 12 for circulating a thermal medium. The output side of the circulating passage 12 is connected with an output heat exchanger furnished on a hot water storing tank, etc. The thermal medium introduced by a pump 10 circulates via the exhaust gas heat exchanger 9, an oil heat exchanger 5, and a water jacket (cooling part) 6A and is discharged. The thermal medium introduced to the heat exchanger 9 is set to a low temperature so that the water vapor in the exhaust gas becomes below its dew point through adjustment of the rate of flow, etc. The thermal medium recovers the heat possessed by the exhaust gas and its heat of condensation and then is led to the cooling part 6A to cause a further temperature rise. In this manner, the exhaust heat of the engine can be efficiently recovered.

摘要： PROBLEM TO BE SOLVED: To provide a cogeneration system which is capable of operating with high efficiency through restraining excessive heat. SOLUTION: A generator selector 36 detects the number of generators which should operate from among generators 10A-10D paged on a power demand and compares the total heat value of the detected number of generators with a heat demand. If the heat demand is smaller than the total heat value, the number of generators matching the heat command are made to operate. If that number of generators is unable to meet the power demand, the balance power is supplemented by power from a commercial power system. If the heat demand is larger than the total heat value, the number of generators matching the power demand are made to operate. If this number of generators is unable to meet the heat demand, the balance heat is supplemented by making the a boiler 37 operate.

摘要： PROBLEM TO BE SOLVED: To operate an engine generator at a high operating efficiency. SOLUTION: The exhaust heat of an engine generator 10 is recovered by a heat exchanger 16 to be utilized in a heat load 17. When heat demand is required, the engine generator 10 is operated by rated power and stopped when heat demand is not required. Namely, when the heat load 17 is lowered to a predetermined temperature or below, a temperature detector 19 outputs a heat requirement signal HRQ, and in response to the heat requirement signal HRQ, a controller 20 starts and operates the engine generator 10 by the rated power. Thus, engine generation is performed only when heat demand is required, therefore excessive heat is not required to be removed by a radiator and the like.
