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.

Conventional solid fuel power boilers burn the fuel in a fixed bed. In a fluidized bed boiler, hot air is blown at a high velocity up through a bed of sand, limestone, and ash causing the solid particles to fluidize, or behave like a liquid. Fluidization provides good mixing and allows for effective combustion when fuel is added.

Pressurized fluidized bed combustion (PFBC) 20 January 2018. FBC in boilers can be particularly useful for high ash coals, and/or those with variable characteristics although PFBC has also been used on a commercial scale in Sweden and Japan with traded coals of higher quality. It is used with a combined-cycle system incorporating both steam and
A fluidized bed boiler feed system for the combustion of pulverized coal. Coal is first screened to separate large from small particles. Large particles of coal are fed directly to the top of the fluidized bed while fine particles are first mixed with recycled char, preheated, and then fed into the interior of the fluidized bed to promote char burnout and to avoid elutriation and carryover.
In a circulating fluidized bed boiler, the large thermal mass and flow characteristics of the solids strongly affect the transient response of the circulating fluidized bed loop temperature, which determines the heat transfer rate to steam flow.

Fluidized Bed Bioreactor. Fluidized Bed Bioreactor Treatment process. The reasons are as follows. Due to the FBBR Media, the Surface area of the Bacteria to the Effluent water is higher by 10 times. Due to attached growth of the Bacteria, the Bacteria count known as MLSS is very high compared to conventional Biological treatment plant.
The model is a systematic approach for modeling a circulating fluidized bed boiler, which is a combination of zero-dimensional energy and mass balance model of heat exchanger blocks. Blocks of heat exchangers are integrated with the air-gas side, the water-steam side, and the solids side.
Principle of Fluidized Bed Combustion When air/ gas passes through a packed bed of fine solid particles at low velocity, the bed remains undisturbed. As the air/gas velocity is steadily increased, the bed particles are found to be in a state of suspension within the stream of air/gas.
