PURPOSE:To improve cooling efficiency by separately providing a cooling water circulation passage running to an exhaust gas cooler and another cooling water circulation passage running to an engine and mounting a cooling water tank and a pump in each cooling water circulation passage. CONSTITUTION:Through a cooling water circulation passage 18 running to an exhaust gas cooler 6, a cooling water in a circulation cooling water tank 20 is sent by a special cooling water pump 21 via a flow rate regulation valve 22 and a radiator cooler 23 into the exhaust gas cooler 6. The water in the exhaust gas cooler 6 is returned to the circulation cooling water tank 20 via water separators 7, 8. Through a cooling water circulation passage 19 running to an engine 1, a cooling water in a clear cooling water tank 25 is fed by a cooling water pump 26 to flow via a lubricating oil cooler 27 and a clear water cooler 28 in sequence and carried back to a clear cooling water tank 25. |
