Design, Manufacturing and Performance Evaluation of House Hold Gasifier Stove: A Case Study of Ethiopia

Abstract

Biomass energy accounts for about 11% of the global primary energy supply, and it is estimated that about 2 billion people worldwide depend on biomass for their energy needs. Yet, most of the use of biomass is in an inefficient manner, primarily in developing countries, leading to a host of adverse implications on human health, environment, workplace conditions, and social wellbeing. Therefore, the utilization of biomass in a clean and efficient manner to deliver modern energy services to the world's poor remains an imperative for the development of community. One possible approach to do this is through the use of efficient biomass gasifiers. Although significant efforts have been directed towards developing and deploying biomass gasifiers in many countries, in Ethiopia especially the gasifiers have technical and economic barriers that hinder house hold gasifier dissemination and application. House hold gasifier stove design, manufacture and scaling up their dissemination remains an elusive goal. This article focuses on identification and evaluation of technical and economical limitations of house hold biomass gasifier stoves manufactured and distributed in Ethiopia. Then designing a family size standard gasifier stove and manufacture and evaluate the performance efficiency of the newly designed house hold gasifier stove. Finally device a mechanism that can improve the overall efficiency and applicability of house hold sized gasifier stoves.
