Parametric Analysis of Fixed Bed Gasifier for Biomass and Urban Solid Wastes: A Review

Abstract

Gasification is the most appropriate technology for converting biomass and other urban wastes into a cleaner gaseous fuels, called producer gas. Producer gas is a mixture of gases consisting of hydrogen, carbon monoxide, methane, carbon dioxide, water vapor, nitrogen, tar and suspended particulate matter. Various parametric aspects of biomass gasification have been discussed in this paper. A brief description of some of the widely used configurations of biomass gasifiers has been done. The effect of various gasifying agents on the quality of producer gas and performance of different types of fixed-bed gasifiers are discussed. The performance of the different fixed-bed biomass gasifier systems is analyzed in terms of reactor temperature, gas calorific value, cold gas efficiency, equivalence ratio, and producer gas composition. Fixed-bed gasifier has been found to produce good quality producer gas for use in chemical industries, power generation or for domestic applications
