PROBLEM TO BE SOLVED: To control water in a water storage tank accurately by means of treatment of water after ammonia is rendered harmless.SOLUTION: If water in a water storage tank 29 is not full, condensed water in a condensed water tank 41 is sent to the water storage tank 29. If the water in the water storage tank 29 is full, the water in the water storage tank 29 is actively neutralized and discharged outside, the condensed water in the condensed water tank 41 is sent to the water storage tank 29, ammonia that is likely to be discharged upon NOx purification is rendered harmless in the water storage tank 29, and the water in the water storage tank 29 is controlled accurately by means of treatment of water after ammonia is rendered harmless. |
