Experimental Studies of Spreri Design Fluidized Bed Gasifier

Abstract

Fluidized beds are used for a broad variety of fuels; this flexibility with respect to different fuels is actually another stronghold of fluidized beds. In terms of the utilized fuels, coal has been most often applied so far, but also waste and biomass have been utilized and are forecast to play a more important role in the future. The fluidization principle is straight forward: passing a fluid upward through a packed bed of solids produce a pressure drop due to fluid drag. Several researchers had worked on bubbling fluidized bed gasifier and use sized biomass like sawdust, rise husk, coir pitch, pomace and olive pits, and coconut shell. But with biomass used as fuel in fluidized bed gasifier with good quality of producer gas can be achieve by changing equivalence ratio and fluidization velocity. In this project work we had tried to use sawdust and pigeon pea (size: 0.4 to 0.841 mm) material as a feed material and sand (size: 0.4 to 0.595 mm) as a bed material for its easiness of fluidization and local availability.
