Other articles where Fluidized-bed combustion is discussed: coal utilization: Fluidized bed: In fluidized-bed combustion, a bed of crushed solid particles (usually six millimetres or less) is made to behave like a fluid by an airstream passing from the bottom of the bed at sufficient velocity to suspend the material in it. The bed material—usually. A fluidized bed may be defined as the bed of solid particles behaving as a fluid. Fluidization is a method of mixing fuel and air in a specific proportion, for obtaining combustion.

During the mid to late s, fluidized bed combustion (FBC) rapidly emerged as a viable option to stoker fired and pulverized coal-fueled units 1984 book the combustion of solid fuels. Initially used in the chemical and process industries, FBC was applied to the electric utility industry because of its perceived advantages over competing combustion Cited by: 2.
In The Efficient Use of Energy (Second Edition), In fluidized-bed combustion, any fuel, e.g. coal, oil or gas, is dispersed and burned in a fluidized bed of inert particles. In most applications the temperature of the bed is maintained in the range –°C so that combustion of the fuel is substantially completed but particle sintering is prevented.
The focus of this thesis is on Circulating Fluidized Bed Combustion. The principle of a fluidized bed is that a bed of solid particles adopts a fluid-like behavior when a gas injected from below flows through it.
A fluidized bed is known to provide a good gas-solids contact together with relatively high rates of solids and gas mixing. TheseCited by: 5. In fluidized-bed combustion, any fuel, e.g.
coal, oil or gas, is dispersed and burned in a fluidized bed of inert particles. In most applications the temperature of the bed is maintained in the range –°C so that combustion of the fuel is substantially completed but particle sintering is prevented.

If the air velocity is increased to m/s then a CFB system can be achieved, where the sand is carried upward by the flue gases and a more thorough mixing of the bed material and fuel takes place.
The densities are also those found at the top of combustion chambers which may be higher than Circulating Fluidized Bed Technology 20 m. It is of interest to understand the solids backmixing and distribution processes under these conditions so that temperature profiles can be estimated throughout the turndown by: 7.
fluidized bed combustion reduces the amount of clinker formation due to the reduce combustion temperatures. Poor combustion Control. Before firing coal in a fluidized bed furnace what step must be carried out that is not necessary for conventional boilers.
heat the inert material about C. Chemical-looping combustion has been discussed earlier in the literature as an alternative to normal combustion (Richter & Knoche, ; Ishida & Jin, ; Anheden, Näsholm, & Svedberg, ).The system is composed of two reactors, an air and a fuel reactor, as shown in Fig.
fuel needs to be in a gaseous form and is introduced to the fuel reactor, which contains a metal oxide, by: FLUIDIZED BED COMBUSTION - a scope of the potential hazards The Fluidized Bed Combustors have specific hazards that could be taken into account in the initial stage of the plant design as well as during the exploitation.
