Abstract

An exhaust gas treatment facility (100) comprises a desulfurizing agent supply unit (10), a combustion furnace (20), an exhaust gas temperature lowering unit (30) , and an electric dust collector (40) . The desulfurizing agent supply unit (10) causes desulfurizing agent to be injected into a position in a vicinity of an upper nose section (21) in the combustion furnace (20), via a desulfurizing agent injecting inlet (14) . A configuration may be adopted in which exhaust gas passes a gas duct (22) to be supplied to the exhaust gas temperature lowering unit (30), and, after having its temperature lowered, has dust removed in the electric dust collector (40) to be emitted to the atmosphere from a chimney (4 9).
