A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Pulverized coal vs. circulating fluidized bed: An economic

For coal-fired plants, this evaluation process includes pulverized coal-fired boilers (PC) and circulating fluidized bed boilers (CFB). The cost difference between these products is site specific and depends on several variables, including: Boiler size, pressure, and temperature; Operating variables, such as the cost for fuel, auxiliary power

Boiler Furnace Design Methods | SpringerLink

In pulverized coal (PC) or circulating fluidized bed (CFB) fired boilers, on the other hand, the combustion and heat transfer to the water walls take place simultaneously in the furnace. As a result, the furnace of a stoker fired boilers will be designed differently from that of the latter two boilers.

CFBC Boiler vs Pulverized Fired Boiler

Jun 02, 2014 · The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel. CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizing.
