After communicating with customers on site, we learned that the main problem to be solved at present is the white smoke generated during the use of steam boilers, accompanied by odor. We have tried adding chemicals before, but none of them can completely solve the problem and are often complained about. In response to this situation, we use condensing mixed air dew reduction flue gas whitening equipment for treatment. After debugging, it can achieve no visible smoke and no odor. After testing, the discharged flue gas meets environmental protection standards and has won praise from customers!
