Fluidised bed combustion is one of the most promising methods of the burning coal in steam power plants. Boiler tubes immersed in the fluidized bed combustor take advantage of the high heat transfer characteristics of fluidized beds.
The steam and hot flue gases generated in this manner may be used to drive turbines to generate electrical power.
To desine such systems intelligently, the mechanistic behavior of fluidized beds must be understood.
For this purpose a ten inch (25.4 cm) cylindrical fluidized bed reactor pilot plant (FBRPP) has been designed for operation at atmospheric pressure and in the range of 700-950 C.
The ten inch diameter for the fluidized bed has emerged as a compromise between a laboratory bench scale and large industrial scale fluidized bed reactors.
This facility can be modified for high pressure operation at a later stage and as a continuation of our current program. This modification will involve some structural changes and some addition instrumentations.
Heat transfer was investigated in our experiment.
It is a major objective of this investigation to determine the influence of parameters such as particle size, bed temperature, fluidizing gas velocity on the water-tube heat transfer corfficients and heat release rates.
