How Circulating Fluidized Bed Boilers Work?

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.

Dynamic model of a bubbling fluidized bed boiler

Due to the intensive circulation, the high heat transfer and high heat capacity of the solids the temperature is constant throughout the boiler [6]. While combustion and heat transfer is high in the bed section of a bubbling fluidized bed, the whole boiler is utilized in the circulating fluidized bed [6].

Fluidized Bed Combustion FBC Boiler Animation. MECHANISM OF FLUIDISED BED COMBUSTION If the sand, in a fluidized state, is heated to the ignition temperature of the fuel and the fuel is injected continuously into the bed, the fuel will burn rapidly and the bed attains a uniform temperature due to effective mixing. This, in short is fluidized bed combustion.

STUDY OF CIRCULATING COAL FLUIDIZED BOILERS

The ash from the fluidised bed, the cyclone and the ESP is conveyed pneumatically to the main ash silo, keeping the plant clean of ash. The boiler is designed with fluidising velocities up to 4.5m/s, generating a high turbulence and resulting in a good mixing of hot bed material with fuel and recirculated fly ash.

Fluidized Bed Combustors for Biomass Boilers

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties.

Fluidized Bed Boilers: Design and Application by Prabir

Oct 22, 2013· Fluidized Bed Boilers: Design and Application attempts to address the need for a single source of information covering all major areas of fluidized bed boiler design and operation. It is based on the International Workshop on Design and Operation of Atmospheric Pressure Fluidized Bed Boilers, organized by the Center for Energy Studies : 4/5Fluidized bed combustion - Wikipediahttps://en.wikipedia.org/wiki/Fluidized_bed_combustionFluidized bed combustion. Limestone is used to precipitate out sulfate during combustion, which also allows more efficient heat transfer from the boiler to the apparatus used to capture the heat energy (usually water tubes). The heated precipitate coming in direct contact with the tubes (heating by conduction) increases the efficiency.
