Circulating fluidized bed(CFB) boiler working principle

Bed Material. To start with the bed material is sand. Some portion is lost in the ash during the operation and this has to be made-up. In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material.

Boiler - Energy Education

The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam. All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of that fuel ends up going into a boiler (the remainder goes into internal combustion engines, which use the fuel differently).

Why We Are Used 6 Mm Coal In Power Plant Boiler

In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions. CFBC uses crushed coal of 3 to 6 mm size. This requires only a crusher not a pulverizer.

USER GUIDELINE FOR COAL BOTTOM ASH and BOILER

The majority of coal bottom ash and boiler slag are produced at coal-fired electric utility generation stations, with some coming from coal-fired boilers or independent coal-burning electric generation facilities. The type of bottom ash or boiler slag produced depends on the type of coal-burning furnace. Bottom ash is produced as a result of burning coal in a dry bottom pulverized coal boiler.
