CFB Boiler Technology and Process-ZBG Boiler

26/4/2018 · The CFB is particularly adept at burning low-grade, high-ash coals and cofiring with other low-grade waste materials. Depending upon the emissions limits imposed on the plant, direct injection of limestone into the bed is often sufficient to meet SO2 removal requirements, without the additional desulfurization equipment found on modern pulverized coal power plants.

What is Circulating Fluidized Bed Technology?

Conventional coal plants use pulverized coal, ground to the consistency of facial powder, and burn it at temperatures between 2,200 F to 2,400 F. In contrast, CFBs use coal in chunks about 3/8-inch in size mixed with limestone and burn it at lower temperatures—1,500 F to 1,650 F. Air is blown into the boiler to suspend, or fluidize, the mixture.
