Abstract

PURPOSE:To prevent deterioration by the antisulfuric acid dew point corrosion resistance of a lead outer tube to improve reliability thereof by interrupting the flowing-in of the waste gas, when the temperature of the waste gas is more than a predetermied temperature, on the waste gas flowing-in side of a waste heat recovering heat exchanger using a lead-covered double pipe type heat transfer pipe. CONSTITUTION:Waste gas from a heating furnace 6 is passed through a duct 4 and clean air is passed through a duct 6 thereby to perform heat-exchange by a heat pipe heat exchanger 1. In a case where the temperature of waste gas of the heating furnace 3 detected by a temperature sensor 17 is more than a set temperature of a control device 18, a motor 21 is driven to close a shutter 20 and prevent the flow- in of the waste gas, and the waste gas is bypassed to the flow-out side duct 4b by oepning a bypass duct 8. In this manner, the flow-in of an abnormal high temperature gas within the heat exchanger is prevented, and the deterioration by the antisulfuric acid dew point corrosion resistance due to the melting of the lead outer pipe is prevented, and the reliability of the heat exchanger can be improved.
