PROBLEM TO BE SOLVED: To completely remove dioxin and the like after soot and dust treatment. SOLUTION: This combustion equipment emits exhaust gas generated from a various type furnace 12 via a dust removing means. A high-temperature and high-heat heat exchanger P durable against a temperature of a dioxin decomposing temperature or higher is connected in parallel with an auxiliary heating means 16 via a bypass to an exhaust gas side of the furnace 12. Low temperature exhaust gas after a dust removing means is introduced into an input side of a secondary air heating tube 4 protected by a high temperature castable refractory material and attached to a high temperature gas channel 7 of a main channel of the exhaust gas of the exchanger P. The exhaust gas is subjected to heat exchange to heat to a high temperature and discharged from its output side. Then, it is cooled by a quickly cooling unit 19 and exhausted. |
