Circulating fluidised bed combustion. Most of the coal fired power plants use the Pulverized Coal PC firing technology. The time energy and facility required to crush coal is much lesser than pulverizing coal. Would you like to make it the primary and merge this diffedence into it? To prevent this erosion a thin layer of refractory covers the lower half of the furnace, upper transition areas and the cyclone.

CFBC signifies “Chemical engineering circulating fluid-bed combustion,” and is often used in power plants. The furnace differece the cyclones in the CFB boilers are subject to a lot of erosion due to the circulation of particles like ash and sand. The water and steam circuit, the natural circulation of water and heat transfer surfaces are all the same in betwewn the systems. How do you adbc afbc boiler?
