Development and testing of improved double skirt rocket stove for reducing the emission level of carbon monoxide

Abstract

Carbon monoxide is very poisonous and spreading rapidly in air, while using three stone open fire food cooking utmost in all parts of rural area. However, the carbon monoxide is very harmful to human being that resulted the severe diseases, like chronic obstructive pulmonary disease (COPD), lung cancer etc. By considering this fact a clean burning and fuel-efficient cooking stove, is designed and develop at Bahir Dar Institute of Technology (BiT), Bahir Dar, which uses mainly eucalyptus and other wood as a fuel. The present paper aims to reduce the requirement of firewood consumption and emission of carbon monoxide of the traditional three stone open fire stove (TSOFS) by replacing an improved double skirt rocket stove (IDSRS) at institutional cooking kitchen. Each part of the stove is designed based on Aprovecho research center design criteria. The emission of carbon monoxide and particulate matters are recorded by digital indoor air pollution (IAP) meter and results are presented. However; insulation material like Pumice; Loam soil; Synthetic asbestos are used for construction of double skirt rocket stove to reduce the value of firewood consumption and also to increase an efficiency of the rocket stove by 41% than the traditional three-stones cooking method and fabricating double skirt IRS to reduce the loss of heat makes the stove differ from previous single skirt stoves.
