Design & Development of Biomass Gasifier Using Agro-Wasteto Produce Producer Gas

Abstract

Biomass will play an important role in the future global energy infrastructure for the generation of power and
heat, but also for the production of chemicals and fuels. Distributed generation (DG) of power has a great potential for
supplying power to the remote areas. The use of gas engine integrated with biomass gasifier is a technologically and
commercially viable option for the decentralized generation. However, the sustainability in the supply of biomass in remote
villages is an important issue. Biomass gasification means incomplete combustion of biomass resulting in production of
combustible gases consisting of Carbon monoxide (CO), Hydrogen (H2) and traces of Methane (CH4). This mixture is called
producer gas. The production of producer gas called gasification and takes place at temperatures of about 1000ºC. The
reactor is called a gasifier. Various types of waste - namely those resulting from Mediterranean farming (rice husk, olive
bagasse, nut shells, etc.) - have been used for energy purposes in power plants equipped with technologies that range from
well-established direct combustion systems to gasification systems that are currently being developed. This paper contains a
description of processes and technologies related to direct combustion and gasification of agricultural & agro-food waste.
