The Difference between Coal - fired Boiler and Circulating Fluidized Bed Boiler in Power Plant
The circulating fluidized bed boiler consists of a separator and a return valve to form a fly ash recirculation system. The change in the size of the fly ash circulation caused by the burning of the coal can adjust the heat absorption and bed temperature in the combustion chamber as long as the fuel is burned
Bed boilers burning, used to burn a variety of poor quality fuel, but the best.
The calorific value is greater than the heat required to heat the fuel itself and the air required for combustion to a stable temperature (850 to 950 ° C), which can be stably combusted in the fluidized bed, so that almost all kinds of coal
1) is particularly good for fuel adaptability.
