Atmospheric Fluidized Bed Combustion

Hence the AFBC Atmospheric Fluidized Bed Combustion Boiler can operate at low excess air -only 20 25.

Atmospheric fluidized bed combustion. The use of fluidized bed coal combustion technology has been developed in the past decade in The Netherlands with a view to expanding the industrial use of coal as an energy supply. Coal of size 0-10mmis spread over bed typically 1-6 mm size for under bed firing and 6-10mm for overbed.

Addition of limestone or dolomite into the fluidized bed is capable of. а Bubbling bed fluidized bed combustor BFBC and б Circulating fluidized bed combustor CFBC. Fluidized Bed Combustion Boiler.

3High Combustion Efficiency. A blower below the belt creates fluidized air which entrains smaller coal particles in a fluidized bed above the larger coal. Fuel and sorbent are introduced either above or below the fluidized bed.

Afbc boiler is suitable for combustion of low quality fuel. The system includes a housing defining a first combustion region. Further AFBC boilers are under various stages of erection and commissioning.

A typical BFB arrangement is illustrated schematically in figure. ISSN 2320-5407 International Journal of Advanced Research 2014 Volume 2 Issue 5 561-574. The bed is composed of sand ash char residue and possibly SO 2 sorbent.

So low excess air is required during combustion. а Bubbling bed fluidized bed combustor BFBC and. Atmospheric fluidized bed combustion systems are presently in fully developed state and these are being used in many power plants.
