Abstract

PURPOSE: To prevent moisture from being concentrated inside the inner wall of an exhaust pipe and improve the durability in a system wherein heat- exchange is executed between exhaust gas and cooling water by measuring the moisture of exhaust gas and the temperature of exhaust pipe and controlling the flow rate of cooling water according to the measurements.
CONSTITUTION: Exhaust gas passing through the exhaust pipe 12 of an engine 11 is heat-exchanged with cooling water passing through a cooling pipe 13 with a heat-exchanger 10. The cooling water, as a result, increased in temperature is fed into a secondary heat-exchanger 14 to heat the cooling water inside a secondary cooling pipe 16. The hot cooling water is then used as hot water in an air conditioner. A moisture measuring apparatus 21 measuring the moisture of exhaust gas inside the exhaust pipe 12 and a temperature measuring apparatus 22 measuring the temperature of the exhaust pipe 12 are incorporated in such system. When the measured moisture of exhaust gas is decided to be higher than the saturated moisture corresponding to the temperature of the exhaust pipe 12, a flow rate control circuit 24 controls a flow rate controller 23 to make control for the flow rate of cooling water for the heat-exchanger 10.
