Abstract

The container unit type cogeneration engine generator comprises a long generator container in which an engine and components on a generator main body side including a generator driven by the engine are accommodated, and a short exhaust heat utilizing container in which a boiler that generates steam and hot water for hot-water supply by utilizing exhaust heat of the engine and an exhaust heat utilizing apparatus including a heat exchanger are accommodated. A combination container unit is configured so that shorter walls on one end side of the both containers in a longer direction are positioned on a same straight line, and making both longer walls of the long generator container and the short exhaust heat utilizing container to face each other. Both containers are coupled with a plurality of pipes along the shorter direction of the containers across the facing walls along which the both containers are arranged.

First claim

The invention claimed is:

1. An apparatus, comprising:
a generator container accommodating a generator and an engine connected with the generator; and
an exhaust heat utilizing container in which steam or hot water is generated by recovering exhaust heat of the engine,
wherein the generator container includes, at least, a first longer wall extending along a first direction and a first shorter wall extending from one end of the first longer wall along a second direction orthogonal to the first direction,
the exhaust heat utilizing container includes, at least, a first longer wall extending along the first direction and a first shorter wall extending from one end of the first shorter wall along the second direction,
the first longer wall of the generator container faces parallel to the first longer wall of the exhaust heat utilizing container, and the first longer wall of the generator container and the first longer wall of the exhaust heat utilizing container are connected by a plurality of pipes, the plurality of pipes comprising a first pipe to transport water to recover exhaust heat from the engine, a second pipe to transport water to the engine, and an exhaust gas port to transport exhaust gas from the engine.

2. The apparatus according to claim 1 ,
wherein the first shorter wall of the generator container and the first shorter wall of the exhaust heat utilizing container are positioned on a same straight line.

3. The apparatus according to claim 1 ,
wherein a size of the generator container comprises a dimension of approximately 12.0 meters, and
a size of the exhaust heat utilizing container comprises a dimension of approximately 6.0 meters.

4. The apparatus according to claim 3 ,
wherein the generator container accommodates a heat exchanger configured to generate the hot water by heat-exchanging with cooling water heated by the engine,
a cooling water outlet port discharging the cooling water heated by the engine and a cooling water return port being in order to return the cooling water to the engine are arranged on the first longer wall of the generator container,
a cooling water inlet port introducing the cooling water to the heat exchanger and a cooling water take-out port being in order to return the cooling water to the generator container are arranged on the first longer wall of the exhaust heat utilizing container,
a first axis line connecting the cooling water outlet port and the cooling water inlet port extends along the second direction, and
a second axis line connecting the cooling water return port and the cooling water take-out port extends along the second direction.

5. The apparatus according to claim 1 ,
wherein the exhaust heat utilizing container accommodates a muffler erected vertically in a height direction of the exhaust heat utilizing container and a boiler generating the steam by heat-exchanging with exhaust gas from the engine,
the exhaust gas port is arranged on an upper wall of the generator container above the engine,
an exhaust gas inlet port is arranged on an upper wall of the exhaust heat utilizing container above the muffler, and
a third axis line connecting the exhaust gas port and the exhaust gas inlet port extends along the second direction.

6. The apparatus according to claim 1 ,
wherein the generator container includes a second shorter wall extending from the other end of the first longer wall along the second direction,
the exhaust heat utilizing container includes a second shorter wall extending from the other end of the first longer wall along the second direction,
a first opening and closing door is provided on the second shorter wall of the generator container, and
a second opening and closing door is provided on the second shorter wall of the exhaust heat utilizing container.
