Circulating fluidized bed boiler adopts circulating fluidized bed combustion (CFBC) technology, that is, the fuel is burned in fluidized state, and the materials flying out of the furnace are collected by the gas-solid separator and returned to the furnace for circulating combustion and utilization. Circulating fluidized bed combustion is a high-efficiency, low-pollution clean combustion technology with the advantages of wide fuel adaptability, excellent environmental performance, wide range of load regulation and easy comprehensive utilization of ash, etc. It is one of the most practical and feasible high-efficiency and low-pollution combustion equipment at present.
① Good fuel adaptability. The fluidized combustion mode of circulating fluidized bed is especially suitable for low-grade coal with low calorific value.
② Large load adjustment range and fast load adjustment. There are a large number of bed materials in the furnace, with strong heat storage capacity. The fly ash recycling system is adopted, with a large adjustment range. The low load can be reduced to about 30% of the full load, and the operating thermal efficiency is basically unchanged.
③ High thermal efficiency.
④ Low power consumption, reasonable primary and secondary air ratio, reduce the wind pressure requirements for fans, and reduce motor efficiency.
⑤ Low emission of combustion pollution. The desulfurization agent such as limestone and dolomite can be directly added to remove sulfur dioxide generated by combustion.
⑥ High combustion intensity. The furnace section area is small, and the heat load per unit section area is high.
⑦ It is easy to realize comprehensive utilization of ash and slag. Low temperature combustion causes low carbon content of ash, which belongs to low-temperature burning.
In order to seek breakthroughs, our company has developed the latest generation of safe, high-efficiency, energy-saving and environment-friendly circulating fluidized bed boiler products based on our own R&D and production of circulating fluidized bed boilers, and in-depth cooperation with Tsinghua University and Chinese Academy of Sciences. Meanwhile, we have strengthened the docking of relevant national energy-saving and environmental protection policies, and combined with domestic advanced circulating fluidized bed boiler operation data.
