Abstract

A short waste-heat reuse container disposed adjacent to a 40-f container that contains a radiator 23, an engine 21, and a power generator 22 disposed in a longitudinal direction of the container, the waste-heat reuse container collecting waste heat of the engine and generating steam or hot water, the waste-heat reuse container containing a muffler 2 that muffles exhaust gas of the engine, a boiler 4 that transfers heat of the exhaust gas to water and generates steam, and a heat exchanger 3 that transfers heat of cooling water heated by the engine to water and generates hot water, wherein the muffler is disposed upright opposite to the boiler in the longitudinal direction of the waste-heat reuse container, an exhaust gas inlet 2a of the muffler being disposed on an upper wall of the container.

Claims

1. A waste-heat reuse container disposed adjacent to a power generation container that contains a radiator, an engine, and a power generator, the waste-heat reuse container collecting waste heat of the engine and generating steam or hot water, a length of the waste-heat reuse container being smaller than that of the power generation container, the waste-heat reuse container containing:

a muffler that muffles exhaust gas of the engine;

a boiler that transfers heat of the exhaust gas to water and generates steam; and

a heat exchanger that transfers heat of cooling water heated by the engine to water and generates hot water.

2. The waste-heat reuse container according to claim 1,

wherein the muffler is disposed upright in the waste-heat reuse container, and

wherein an exhaust gas inlet of the muffler is disposed on an upper wall of the waste-heat reuse container.

3. The waste-heat reuse container according to claim 1, containing:

a boiler that transfers heat of the exhaust gas muffled by the muffler to water and generates steam;

or

a heat exchanger that transfers heat of cooling water heated by the engine to water and generates hot water,

wherein a center axis of a pipe that connects the boiler and the muffler is straight in a longitudinal direction of the waste-heat reuse container.

4. The waste-heat reuse container according to claim 1,

wherein the exhaust gas inlet of the muffler is disposed along a transverse direction perpendicular to the longitudinal direction of the waste-heat reuse container so that the exhaust gas inlet faces an exhaust gas outlet of the power generation container.

5. The waste-heat reuse container according to claim 1,

wherein open/close doors are disposed on each transverse wall on both ends in the longitudinal direction of the waste-heat reuse container so as to open the transverse wall.

6. The waste-heat reuse container according to claim 1,

wherein the boiler is disposed on one end in the longitudinal direction of the waste-heat reuse container, and

wherein the muffler that muffles the exhaust gas and the heat exchanger that transfers heat of the cooling water heated by the engine to water and generates hot water are disposed on another end in the longitudinal direction and on both sides in the transverse direction of the waste-heat reuse container.

7. The waste-heat reuse container according to claim 1,

wherein an inlet and an outlet for cooling water heated by the engine and cooled by the heat exchanger are disposed on an inner wall of opposite walls in the longitudinal direction of the waste-heat reuse container, and

wherein an inlet and an outlet for clean water heated by the heat exchanger are disposed on an outer wall of the opposite walls in the longitudinal direction of the waste-heat reuse container.
