Summary:PROBLEM TO BE SOLVED: To provide an aqueous ammonia vaporizer for a denitrating device capable of providing a high NOx purification effect without tremendously increasing cost. SOLUTION: This aqueous ammonia vaporizer comprises a flue gas extraction port 9 extracting a part of flue gas 18 from a waste heat recovery boiler 2, an ammonia vaporizer 13 generating ammonia gas by vaporizing aqueous ammonia 19, a flue gas extraction fan 12 leading the flue gas 18 extracted from the flue gas extraction port 9 to an ammonia vaporizer 13, and a flue gas heater 11 for heating the extracted flue gas 18. When the temperature of the flue gas is low, the flue gas 18 is heated by the flue gas heater 11. COPYRIGHT: (C)2004,JPO&NCIPI
