In order for the combustion gas to efficiently react with ammonia and the catalyst, the reaction temperature must be 300 ° C. The gas discharged from the bag filter 250 is cooled to a temperature of 180 ° C. Therefore, the heater 271 heats the combustion gas passing through the heater 271 by using a fuel such as LNG mixed with air to raise the temperature of the combustion gas to 300 ° C. In addition, a catalyst filter of a noble metal such as platinum may be embedded in the heater 271 to remove harmful substances of dioxins remaining upon heating.

Accordingly, the temperature of the gas passing through the heater 271, the reactor 272, and the catalyst 273 is 250 ° C., and the catalyst 273 is relatively hot at the gas discharged from the bag filter 250. By passing the gas discharged from the heat exchanger 274, the temperature of the gas flowing into the heater 271 can be raised to some extent. That is, the temperature of the gas flowing into the heater 271 may be increased to 200 ° C. by using the discharge gas temperature of 250 ° C. discharged to the outside, thereby saving energy consumed in the heater 271. .
