Abstract
PURPOSE: To remove a nitrogen oxide economically and effectively by a method wherein the quantity of a denitrification agent being supplied is increased in a high temperature region, in which the temperature of exhaust gas is high, and the quantity is decreased in a low temperature region per a transverse section of a flow path for the exhaust gas.
CONSTITUTION: The quantity of a denitrification agent supplied is increased in a high temperature region, in which the temperature of exhaust gas is high, and the quantity is decreased in a low temperature region per a transverse section of a flow path for the exhaust gas containing a nitrogen oxide. For example, fuel is burnt by means of a combustion apparatus 2 of a boiler 1 and changed into exhaust gas with a high temperature, and exhausted through an economizer 6 and a chimney. An injection pipe 7 for the denitrification agent is 5W6m long, has a number of nozzles, and atomizes the denitrification agent from the nozzles. In this case, the temperature of the exhaust gas is low at the left and right furnace wall sides and is high at the center portion regarding the flow rate width W of the exhaust gas. Thus, the quantity of the denitrification agent supplied is decreased at a and b portions close to the furnace walls, and the quantity is increased at the center portion.
