      How to Control Steam Boilers Air Pollution | Coal Fired

      Air pollution has always been a serious environmental problem. The combustion of fuels, especially in power plant boilers or large scale cfb boiler, provides the large part of earth’s energy needs. Despite providing useful heat to generate power, there are unwanted byproducts generating from the process, which are the stack gases. Normally, the unwanted byproducts will pollute the environment.
