Abstract

PURPOSE: To easily and effectively remove NOx from exhaust gas, by utilizing a stage combustion mechanism and mainly using the exhaust gas containing a large amount of NOx as primary air.
CONSTITUTION: For instance, a two-stage combustion furnace is used. Fuel 1 is supplied by a pump 2 and atomized into a primary combustion chamber 4 from a burner tip 3. The primary combustion of the fuel is effected by using the exhaust gas containing the NOx and less than the theoretical air quantity as the primary air 7 so that the NOx is decreased. The combustion gas is completely burned in a secondary combustion furnace 5 supplied with secondary air. The NOx in the exhaust gas 11 is decreased to about one fifth. A fan 6, a sampling position 10, a NOx container 12 and a NOx flow rate regulator 13 are also shown in Fig.
