30t-200t fluidized bed boiler
Release time: 2021-06-16
Circulating fluidized bed boiler is a new type of coal-fired boiler with high efficiency and clean combustion. It has the characteristics of high efficiency and energy saving, stable operation, sufficient output and high thermal efficiency.
Main features of circulating fluidized bed boiler:
1. Fuel adaptability is strong, which can meet the combustion of various fuels.
2. High degree of automation, which can keep the boiler safe and economic operation for a long time.
3. The boiler combustion efficiency is as high as 95% ~ 99%, the fuel utilization rate is high, the boiler thermal efficiency is as high as 87%, energy saving and high efficiency.
4. The high-temperature cyclone separation device with upper exhaust has high bed material collection rate, high furnace heat transfer coefficient and strong overload capacity.
5. The adjustment range of boiler load is large, which can be adjusted in the range of 110% ~ 30%, especially suitable for the occasions with large fluctuation range of boiler load.
6. Limestone can be added to the bed material, which can react with SO2 in flue gas to form sulfate during combustion, so the desulfurization effect can meet the requirements of environmental protection. At the same time, the furnace combustion temperature is low, which can inhibit the generation of NOx, so as to achieve environmental protection combustion.
