<p>PURPOSE:To prevent the fall of the temperature of exhaust gas and to carry out the denitration smoothly by using an evaporating medium having enough temperature for evaporating in order to once evaporate NH3-water and thereafter by pouring the evaporated NH3-water into an exhaust gas duct as NH3 mixed gas. CONSTITUTION:NH3-water is introduced into an evaporator from an NH3-water tank and is evaporated by means of the evaporating medium such as high- temperature air or exhaust gas, etc., to form NH3-containing gas, which is poured into the exhaust gas duct. The use of the gas turbine compressor outlet air or the gas turbine outlet exhaust gas of a thermal power generation apparatus, etc., equipped with a denitrating apparatus is advantageous as the evaporating gas source.</p> |
