PROBLEM TO BE SOLVED: To obtain control of temperature simple in the structure and excellent in the responsibility as a means for adjusting the temperature of a stack gas from incineration equipment. SOLUTION: In this device, a bag filter is provided in a flue connecting to an incinerator and a water cooling type first heat exchanger and an air cooling type heat exchanger 20 are provided in series to be interposed in the upstream side than the bag filter in the flue, a flow rate of cooling air fed to the second heat exchanger 20 positioned in the lower stream side is constitute so as to be changeable, the device is miniaturized by the first heat exchanger having large cooling performance and the temperature of a stack gas can be exactly controlled with the second heat exchanger 20 superior in heat responsibility. |
