FLUIDIZED BED COMBUSTION While the pulverized coal-fired boiler represents the most efficient type of coal- fired power plant, there are alternatives. One of these is the fluidized bed boiler. This type of combustion system is capable of burning a much wider range of fuels than a PC plant. It operates at a lower temperature, making
The coal is used as boiler fuel has volatile matter from 8 to 33 % and ash content 5 to 16 %. To increase the thermal efficiency, the coal is used in the boiler in powder form. Circulating fluidized bed combustion as a clean combustion technology is used in boilers and the coal fired CFB boiler is more and more applied in thermal power plant.
Simultaneously, hydrated lime will be injected into the circulating fluidized bed absorber for reaction to take place to convert SO 2 and SO 3 from the flue gas to calcium sulfate and calcium sulfite. Water will also be injected at the same time to control the operation temperature for maximum absorption capacity.

In this paper, a three-dimensional Eulerian–Lagrangian model is established to perform the full-loop simulation of the combustion process of municipal solid waste (MSW) and coal in an industrial-scale circulating fluidized bed (CFB) boiler. On the basis of the multiphase particle-in-cell (MP-PIC) scheme, the gas phase is modeled by a large eddy simulation (LES) approach and the solid phase
Atmospheric circulating fluidized bed (ACFB) boiler efficiency is comparable to pulverized coal boiler efficiency (86 to 88 percent). Bubbling bed boilers are not included in this discussion not only because they are less fuel efficient, but also
velocity or fast beds. Outside of the pulp and paper industry there are some 60 bubbling fluid bed boilers in operation in a broad cross section of industries. Most of these boilers are coal fired, With this proliferation of applications and terminologies one should ask why and how circulating fluid bed boilers are
