Fluidized Bed Combustion is the ignition of a solid fuel under the conditions mentioned above.. We, At Thermodyne, Boiler Manufacture in India, We design and manufacture Boilers with Bubbling Fluidized Bed Combustion (BFBC) Circulating Fluidized Bed Combustion (CFBC).; Bubbling FBC is used for Fuels with lower heating values such as Rice Husk.. Under such sort, the main factors leading to

For the design of a fluidized-bed boiler the first step is to calculate the fuel-feed rate according to the required thermal output of the boiler with a targeted efficiency. Then the stoichiometric air supply requirement is calculated, which is further enhanced by the design excess air quantity. It is also essential to estimate the net heat

“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

Considering available short discussions in few papers, data obtained in bubbling FBC conditions are used so far, for CFBC boiler design, due to the very expensive equipment for investigation processes in the circulating fluidized bed conditions.
