Development of laboratory model of fluidized bed gasifier for low density leafy biomass

Abstract

Crops can also be grown for energy could be produced in large quantities, and likely to become the most popular in the future. One of the most widely used renewable energy source for heating is biomass in the form of fuel wood, charcoal, agriculture residues etc. A lab model of Fluidized Bed Gasifier (FBG) for handling low density and leafy biomass materials like rice husk, saw dust, bagasse, tree leaves etc. was developed. The performance study of the gasifier was determined by different parameters such as air factor, gas yield, calorific value and hot gas efficiency. The average gas yield of 2.5 m3/kg and a maximum possible feed rate 10 kg/h with the existing feeding system the capacity of the unit was worked out as 20kW.
