Abstract
PURPOSE: To enable to easily remove the above mentioned sulfate, by inducing power of a fixed inactive subustance in combstion exhaust gas of low temperature zone.
CONSTITUTION: More than one kind of the following powders are added in combustion exhaust gas from the space between the coal economizer and air preheater, at the publicly known fuel oil combustion boilder carrying out reducing decomposition of NOx in the exhaust gas, by adding ammonia in more than 700°C of combustion exhaust gas produced from combustion chamber. More than one kind of powders of diatomaceous earth, zirconium sand, pearlite and titanium oxide and/or metal powders, such as each powder of Al, copper and iron, are used for the above adding powders. Also, about 0.1W100μ of grain diameter is preferable and a good result is obtained by adding in such a concentration in the exhaust gas as about 100mgW20g/Nm3.
