Design Theory of Circulating Fluidized Bed Boilers

A concept model of material balance for the open system of CFB boiler was developed and later improved as a more comprehensive 1-D model taking ash formation, particle attrition and segregation in bed into account. Some results of the models are discussed. Then the concept of State Specification of a CFB boiler is defined and discussed.

Fluidized bed - Wikipedia

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and

Professional CFB Boilers For Power Plant, Fluidized Bed

But they are quite different. Early circulating fluidized bed boilers had relatively high fluidization speed, so they were called fast circulating bed boilers. The basis theory of fast bed can also be used in circulating fluidized bed boilers. The basic theories of bubbling bed and fast bed have been studied for a long time.

WO2011007618A1 - Combustion method for fluidized bed

Disclosed is a combustion method for a CFB boiler (1) that uses biomass fuel. The combustion method is characterized by adding a ferronickel slag to the biomass fuel which is burned in the fluidized bed boiler. The generation of alkali-silicates is suppressed because oxidized magnesium is contained in the ferronickel slag. Consequently, there is decreased danger of poor fluidity arising in
