COAL-FIRED POWER PLANTS:FLUIDIZED BED COMBUSTION

The circulating bed can remove 90–95% of the sulfur from the coal while the bubbling bed can achieve between 70% and 90% removal. Maximum energy conversion efficiency is 43%, similar to that of a traditional pulverized coal plant.

Circulating fluidized bed - Wikipedia

For circulating fluidized bed in coal combustion, the beds need to use a greater fluidizing speed, so the particles will remained constant in the flue gases, before moving across the combustion chamber and into the cyclone. During combustion, a dense bed is required to mix the fuel even though the solids are dispersed evenly all over the unit.

How Circulating Fluidized Bed Boilers Work? - Bright Hub

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air

Oxy-fuel combustion in circulating fluidized bed boilers

Jul 15, 2014· The conditions for CO 2 reduction in a circulating fluidized bed (CFB) oxy-boiler are studied, that is, operation with pure oxygen, diluted by recirculated flue gases to moderate the combustion process. Two cases are analyzed: the ready-to-convert case, a normal air-fired CFB boiler, only slightly modified to be operated with oxygen instead of air for CO 2 capture, and a more general …

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.
