Most of the coal fired power plants use the Pulverized Coal (PC) firing technology. The technology is proven and is in use for nearly a century. Advances over the years have improved the efficiency of combustion, reliability and reduced emissions. The emerging technology of Circulating Fluidized Bed (CFB) combustion is different in many ways from PC combustion.

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

High Efficiency - FBC boilers can burn fuel with a combustion efficiency of over 95% irrespective of ash content. FBC boilers can operate with the overall Thermal efficiency of 82% (plus or minus 2%). Compact in Boiler Size - High heat transfer rate over a small heat transfer area immersed in the bed result in overall size reduction of the boiler.

Mar 04, 2020· The evaporator tubes of boiler are directly immersed in the fluidized bed and the tubes, being in direct contact with the burning coal particles, produce very high heat transfer rates. Because of this, the unit size is reduced to a great extent, and also produces combustion with very high efficiency. Types of Fluidized Bed Combustion
