Efficiency improvement coal fueled CFB steam boiler
Circulating fluidized bed (CFB) technology offers low-temperature combustion, resulting in nitrogen oxides (NOx) emissions much lower than coal-powder boilers. This system allows for direct desulfurization during the combustion process, making it an economical and high-rate desulfurization solution.
Technological variants include Internal and Exterior circulating fluidized bed boilers:
This clean coal technology has matured over 20 years, providing wide fuel adaptation, low NOx emissions, and strong load adaptability for urban central heating and power plant requirements.
