COMBUSTION SYSTEM

WIPO Patent Application WO/2020/161875

A1

The invention can suppress the clogging of a heat exchanger even if the deterioration of a denitrification catalyst, used in a denitrification device, proceeds. The combustion system 1 comprises: a boiler 10 for burning a fuel; an exhaust passage L1 through which an exhaust gas generated from burning the fuel in the boiler 10 flows; and an air preheater 30 which is disposed in the exhaust passage L1, causes a heat exchange between the exhaust gas and combustion air, and supplies the heat-exchanged combustion air to the boiler 10 while discharging the heat-exchanged exhaust gas. In a stage after the air preheater 30, a denitrification catalyst is coated in the exhaust passage L1. In the denitrification catalyst, vanadium pentoxide is present at an amount of 43% by weight or more, and the BET specific surface area is 30 m2/g or greater. The denitrification catalyst is used for denitrification at 200°C or lower.
