A circulating fluidized bed (CFB) Boiler is a combustion chamber where various types of fuel are used to generate steam. CFB boilers are clean and environment-friendly boilers, which use a wide range of coal ranging from low quality coal, coal blends, pet coke and various alternative fuel sources. It reduces harmful emissions such as sulphur dioxide, nitrogen oxide, and carbon dioxide.
Circulating Fluidized Bed (CFB) boiler of Zhengzhou Boiler Co.,Ltd. is characterized by its compatibility with a wide variety of fuels including: low-grade coal, biomass, sludge, waste plastics, and waste tires, etc., whereas conventional boilers for power generation are available only for fossil fuels, such as high-grade coal, oil and gas. As the needs for a fuel shift are rising in response to the current CO2 emission reduction issues and the soaring oil prices, CFB boiler technology is increasingly attracting attention as a viable solution. Additionally, CFB boilers offer benefits such as low pollution, high-efficiency combustion, space saving, and high maintainability. ZG Boiler’s CFB Boiler technology is expected to be at the forefront of next-generation environmentally conscious boilers.

Main parameter of CFB Boilers
1, Fuel: bituminous coal, lean coal, anthracite, petroleum coke,biomass and so on
2, The combustion system of fluidized bed boiler: combustion chamber, material collector and return feeder.
3, Combustion process: High temperature fuel under the entrainment of air into the material collector, the collected material into the recycle device, then through the recycle device to the combustion chamber
4, Capacity:10t/h-50t/h
5, Pressure:1.25MPa-4.5MPa(12.5bar-45bar)
6, Temperature: 194℃,204℃,450℃, or design depending on your requirements.
