摘要： [PROBLEMS] To while keeping facility cost and operating cost low, efficiently remove from a cement kiln firing waste gas any hazardous substances, such as dust, NOx, residual organic pollutants, volatile organic compounds, CO and odorous substances. [MEANS FOR SOLVING PROBLEMS] There is provided firing waste gas treating apparatus (1) comprising dust collection unit (6) for collecting of dust from cement kiln firing waste gas (G1), wet dust collector (7) as a catalyst poisoned substance removing unit for removing of catalyst poisoned substances from firing waste gas (G2) having passed through the dust collection unit (6), preheating units (10,11) for preheating of firing waste gas (G3) having passed through the wet dust collector (7), and catalyst unit (12) for removing of NOx, residual organic pollutants, etc. from the preheated firing waste gas. A titanium/vanadium catalyst or the like as oxide catalyst is used in the upstream side of the catalyst unit (12), while a platinum catalyst or the like as noble metal catalyst is used in the downstream side thereof. The firing waste gas after removing of catalyst poisoned substances is heated to >= 140°C by means of the preheating units, thereby preventing any drop of the efficiency of denitration and volatile organic compound decomposition.
