Abstract
PURPOSE: To reduce the NOx concentration at good efficiency in the comparatively low temperature region, by adding the organic compound possessing NH3 and OH group to the waste gas including NOx and O2.
CONSTITUTION: NH3 is injected from the tank 5 into the waste gas line laid nearby the high temperature reheater of the boiler 1, and additionally, the organic compound possessing OH group (ethanol for example) is injected from the tank 6 into the waste gas line whose temperature is about 400W1000°C, most desirable 450W 800°C. Along the waste gas line, the reaction of following formula mainly proceeds and NOx is reduced and removed. 4NO+4NH3+O2→4N2+6H2O. Next, the treated gas after the denitrification is desulfurized by the desulfurization apparatus 3 through the air preheater 2 and is exhausted from the chimney 4.
