Coal Boiler, Industrial Boiler, Pulverized Coal Boiler - Taishan Group's Improvement on The Cyclone Separator of CFB Boiler
Among them, a major breakthrough was made in CFB boilers-CFB boiler cyclone separator patent. As we all know, the cyclone separator is one of the core components of the CFB boiler. After the fuel is burned, the produced fly ash is passed through the cyclone separator, and the solid particles in it are separated from the flue gas.
