CFB Coal Fired Boiler
1. Circulating fluidized bed boiler is of low temperature combustion, therefore, nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurized during combustion process. Circulating fluidized bed boiler with high desulfuriation rate is economical.
2. Circulating fluidized bed boiler could adopt various coal types and has high combustion efficiency, which is especially suitable for low quality, low calorific value coal.
3. The ash of circulating fluidized bed boiler is of high activity, thus it s easy to realized comprehensive utilization without secondary pollution.
4. Circulating fluidized bed boiler could adjust its load in a wide range. Lowest load can be reduced 30% of full capacity.
