Title:
Denitrogenization system
Document Type and Number:
Japanese Patent JP6064498
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce fuel consumption of a burner device, which raises a temperature of a denitration catalyst, by devising an air supply.SOLUTION: A denitration system comprises: a supercharger 120 which has a turbine 122 rotating with exhaust gas X1 exhausted from an engine 112 and a compressor 124 compressing air using rotation of the turbine 122 and introducing the compressed air into the engine 112; a denitration line 220 which has a denitration catalyst 224 inside the same to enhance reduction of nitrogen oxide contained in the exhaust gas X1 exhausted from the engine 112 and discharges the exhaust gas X1 to an outside; and a burner device 240 which generates combustion gas by combusting fuel using the air compressed by the compressor 124 and introduces the combustion gas into an upstream side of the denitration catalyst 224 in the denitration line 220.
