Has anyone used circulating ammonia water in chimneys to reduce SO[sub]2[/sub]? Does it affect the flue gas waste heat boiler?
Thread Content
Are there any manufacturers that spray ammonia into chimneys to reduce SO2? Is there any salt accumulation in the waste heat boiler tube bundle, and what is salt mainly made of?
I urge fellow sailors to offer suggestions on how to deal with salt buildup Is it okay to rinse with water?
According to what you said, it should be sulfurous acid and ammonium carbonate; water should be sufficient to wash them away, but it’s necessary to consider whether there could be other effects on the equipment (such as corrosion)
If you use this method in winter, the suction force in your chimney can drop below 100 Pascals. Don’t ask me how I know that. I advise you not to try.
When I carried out the spraying, I shut down the waste heat boiler and closed both the inlet and outlet.
