We evaluated heat recovery efficiency of a fin and tube type heat exchanger using exhausted gas foam drying furnaces in an actual factory in order to confirm feasibility to apply a high temperature type heat pump as a heat source of a manufacturing process. Heat of 200 kW is required for a heat pump source in the present study, we conducted the consecutively operation for more than two months using a 6.7kW test model heat exchanger. As a result, the performance of the heat exchanger depended on exhausted gas temperature and gas flow rate, and then we estimated that 200 kW was sufficiently obtained under the condition of 110 ℃ and a flow rate of 202 m^3/min. In addition, degradation in performance was not observed. Thus, the same or similar kind of exhausted gas is considered to be appropriate as a heat source for the heat pump.
