摘要： PURPOSE: A temperature increase system for boiler emission gas capable of removing nitrogen oxide is provided to remove the nitrogen oxide included in the emission gas by increasing temperature of the exhaust gas with a bypass duct. CONSTITUTION: A temperature increase system for boiler emission gas includes the following: a boiler(10) installed on one side of a facility(100); a main duct(40) discharging the emission gas discharged through a fuel economizer(21) through a boiler; a bypass duct(50) supplying the emission gas to a nitrogen oxide reduction device(30) after bypassing the emission gas from the top of the fuel economizer; and a bypass duct damper installed inside the main duct and the bypass duct. The emission gas of low temperature and bypass gas are uniformly mixed and adjusted in a temperature of 310-400°C.
