Performance Evaluation of Developed Domestic Cook Stove with Jatropha Shell

In this study, SPRERI gasifier stove and double pot improved household cookstove were tested with Jatropha shell. Thermal performance and pollutant emissions during water boiling test were evaluated. Jatropha shell combust properly in SPRERI gasifier stove and thermal efficiency was recorded about 31.10%. In case of double pot improved cookstove mixed fuel (1:1) Jatropha shell and babul wood was used for testing and its thermal efficiency was about 22.88%. Lower pollutant emissions were recorded in double pot improved cookstove as compared to SPRERI gasifier stove. Developed stove have acceptable durability, affordable cost, and meet needs of domestic energy requirement. Results of this study may be useful for improving the design of existing stoves and for developing new stove designs. Implications of better agro residue based cookstoves are improved human health, reduced fuel use, reduced deforestation, and reduced global climate change, apart from recovery energy from such agro residues which are not used as animal feed and are disposed off under non-hygienic conditions.
