The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures.
Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

This book provides practicing engineers and students with insight into the design and operation of circulating fluidized bed (CFB) boilers. Through a combination of theoretical concepts and practical experience, this book gives the reader a basic understanding of the many aspects of this subject.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
bubbling fluidized bed (BFB) used primarily for waste coal or biomass 1 Cyclone boilers are similar to PC boilers but do not require extensive fuel grinding and are used for coals, wastes, and other fuels not suitable for PC operations.
The largest pressurized fluidized bed power plant in operation is a 360 MW unit in Japan. This plant, with a supercritical boiler, has a claimed efficiency of 42%. Although commercial fluidized bed power plants with capacities of over 400 MW are available, the units have not proved as efficient as supercritical PC power plants for coal combustion.
Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.
We have in-depth expertise in coal, gas and oil-fired utility plants, industrial plants including pulp and paper mills, petrochemical systems and municipal power operations, HRSGs, fluidized bed boilers, emission control systems, and pulverizers.
The boilers produce steam at 400 pounds pressure and 750 degrees F. The steam is used to generate electricity, heat the campus and to produce chilled water for cooling the campus. Two boilers are circulating fluidized bed boilers that burn coal and utilize limestone to minimize emissions.
Fluidized Bed Combustion System. Fluidized bed combustion systems are able to reduce SOx by primary measures only down to approximately 150 mg/m3 STP by means of adding dolomite directly into the coal feed where it reacts with the sulfur to form CaSO4 (gypsum), with the result that no further bonding agent is required for the ash product to set when water is added.
fluidized-bed combustion. (2) SOx level of approximately 5 ppm through in-bed desulfurization; NOx level of approximately 100 ppm through low-temperature combustion (approximately 860oC), and dust of less than 1 mg/Nm3 by CTF.
