Abstract

PURPOSE: To achieve high and satble denitration rate by re-distributing denitrated gas to the air preheater of each boiler after denitrating the exhaust gas from the multi number of boilers at one denitrating device.
CONSTITUTION: The exhaust gas from the bolers 11 is conducted to one common denitrating device 15 through the exhaust ducts 13 to be denitrated. The exhaust gas denitrated at the denitrating device 15 is re-distributed to each preheater 14 through the branch duct 16. At the preheater 14, the combustion air sent into the combustion chamber of the boiler 11 through the air feeding duct 12 is preheated by exchanging heat with the denitrated gas. The denitrated gas after preheating the combustion air is discharged into the atmosphere through the dust collecting, denitrating, and stack devices 17.
