EXHAUST GAS TREATING DEVICE

摘要

An exhaust gas treating device which has a burner section, and a combustion chamber disposed downstream of the burner section, which produces a combustion flame that is directed from the burner section toward the combustion chamber, and which introduces exhaust gases into the combustion flame to oxidize the exhaust gases for decomposition, wherein, since the combustion chamber has its inner wall formed of fiber-reinforced ceramic material, the heat resistance and corrosion resistance of the inner wall are improved and at the same time since the inner wall exerts no catalytic effect, generation of thermal NOx is suppressed. Further, since the burner section has a cooling means installed in a supporting gas inlet section, ignition and explosion of the supporting gas are prevented. Further, deposition of dust is prevented by the formation of a swirling flame produced by the burner section or it is prevented by a deposition preventing means or a scraping means.
