<p><P>PROBLEM TO BE SOLVED: To provide a method for treating waste gas with high thermal energy efficiency and an apparatus for waste gas treatment in which the neutralization efficiency of a neutralizing chemical can be maintained high without decreasing temperature, an adverse influence as poisoning of a denitration catalyst in denitration equipment can be avoided and re-heating of the waste gas in the upstream side of the denitration equipment is not required. <P>SOLUTION: A chemical 14 for neutralizing the acidic gas component in the waste gas is introduced into the waste gas, fly ash and/or reaction products in the waste gas are treated by a dust collector 3, and then the gas is denitrified in the denitration equipment 6. As for the chemical, sodium-based chemicals are used in the method for treating waste gas and in the equipment for waste gas treatment. <P>COPYRIGHT: (C)2004,JPO</p> |
