The cooling water that comes out after cooling the oil pan 4 of the prime mover 1 has a temperature of 84 (°C), and this cooling water exchanges heat with the operating hot water that passes through the water/water heat exchanger 5. At the outlet of No. 5, the temperature is lowered to SO (°C). This cooling water is then used again as cooling water for the prime mover 1. By the way, the hot water whose heat is recovered as operating hot water is low temperature water of 63 (℃), and this hot water is heat exchanged with the cooling water 84 ('C) in the water/water heat exchanger 5 and is heated to 81 (℃). . This hot water then passes through the exhaust F-JST 8 at approximately 520 (℃) and
The temperature of the water is further raised to °C and stored in the hot water accumulator 9. Hot water from hot water accumulator 9 is sent to preheater 1
2, the temperature is raised to 93 (℃) and it comes out. And on the other hand,
This hot water is gradually heated by the steam generator 13, vaporized, and stored in the steam accumulator 14. In this steam accumulator, surplus steam is stored as thermal energy of saturated water due to heat balance, and when steam consumption increases, the stored thermal energy is supplied as evaporated steam by self-evaporation. On the other hand, 93 (
℃) hot water is provided by a heater 15 and an absorption refrigerator 16a.

The use of gas turbine prime mover 1 at PS/1800 rpm drives a 100 kW three-phase alternator, and steam at 9/crlL"#/H is supplied to 5 by 90 Yu and 93 (
'C) Operational hot water of 25101/H is obtained. Note that the hot water value shown above is an example, and is not limited to this, and varies depending on the scale of the prime mover 1.

バイパス路１９を設けることであってもよい。Needless to say, the operating rate of the prime mover 1 varies depending on the amount of power consumed by the generator 2. For example, there are cases where the required amount of power consumption is small, but on the other hand, a large amount of hot water is required for operation. In such a case, the exhaust gas temperature of the prime mover 1 decreases, making it impossible to supply hot water at a predetermined temperature to the hot water accumulator 9. Use hot water as operating hot water. Furthermore, when restarting the prime mover 1 cannot be expected, it is also possible to operate the auxiliary heater 10 to raise the temperature of the hot water accumulator 9 and use it as operating hot water. Note that the auxiliary heater 10 may generate heat electrically or may utilize steam from the steam accumulator 14. In addition, the hot water in the hot water accumulator V-9 is heated through the preheater 12, but if the hot water in the hot water accumulator 9 has a predetermined temperature or higher, it does not pass through the preheater 12 through the bypass path shown by the chain line. 19 may be provided.

In other cases, the operating hot water can be led directly to the hot water accumulator 9 via the bypass path 20.

おる。As explained above, according to the present invention, a generator is driven by the power of a prime mover such as a gas turbine or a diesel engine, while heat is recovered from cooling water and combustion exhaust gas from the prime mover and used as hot water for air conditioning, hot water supply, drying, etc. In addition to being usable, the hot water can be vaporized and supplied as steam from the steam accumulator, and the hot water used as operating hot water can be recycled and furthermore, the hot water can be stored in the hot water accumulator, so the operating rate of the prime mover is low. In some cases, hot water can be supplied as operating hot water from a hot water accumulator. In this way, the accumulative cogeneration system of the present invention can effectively utilize the combustion exhaust gas of the prime mover.
For example, it is very suitable for being attached to a general hospital or an apartment building such as an apartment building, and has the effect of saving energy.
