PROBLEM TO BE SOLVED: To provide a system for supplying ammonia to an SCR converter which uses water solution as an ammonia generation source and can effectively use water with NHsolved therein when water is removed.SOLUTION: When an SCR converter 21 is connected to an exhaust gas pipe 20 of a diesel engine and ammonia is supplied to the SCR converter 21, an ammonia source is stored as powder in an ammonia source tank 10, ammonia source powder is supplied from the ammonia source tank 10 to an ammonia source water solution production tank 13 and water is supplied to the ammonia source water solution production tank 13 to produce ammonia source water solution. The ammonia source water solution is heated by a heater 17 to produce ammonia gas, which is passed through a cooling pipe 18 to condensate and separate water vapor, the ammonia gas with water vapor separated therefrom is supplied to the SCR converter 21, and condensation water cooled in the cooling pipe 18 is returned to the ammonia source water solution production tank 13. |
