Abstract: Coffee growing areas in Tanzania have abundant coffee husks resources; however these resources are not efficiently utilized in the existing stoves. The main objective of the study was to develop, fabricate and evaluate the performance of gasifier stove that uses coffee husks as source of energy for household cooking purpose. Kalinzi village in Kigoma region was taken as case study for this project. The results for this project were achieved through different methods including visiting Kalinzi village to collect some preliminary data, conceptual design, and design analysis, fabricating and testing the performance of the existing and developed stoves. The result shows that thermal efficiency was improved from 12.8% of the existing stove to 24% for the developed stove. Not only thermal efficiency but also burning rate become lower (5.2 gm/min) for the developed stove than existing stove (14.5 gm/min). Specific fuel consumption has changed from 200 (gram coffee husk/ kg water) to 100 (gram coffee husk/ kg water) of existing stove and developed stove respectively.
