Pengembangan Tungku Briket Batubara Skala Rumah Tangga

Abstract

Improving of a coal briquette stove is required in the context of energy diversification for strengthening national energy security. The policy of kerosene conversion to LPG is a short term policy and needs other source of energy alternative. In idealized sense, all potentials should be used for household cooking, not always depending on a particular energy source. Purpose of this research was to improve a household coal briquette stove to increase stove efficiency and ease in ceasing the ember. Design criteria of the coal briquette stove were based on heat transfer from the burning coal to the heated object, ease in ceasing the ember, and facilitating the exhausting smoke from the kitchen room. Performance test to the designed stove was conducted on analyses of temperature at the bottom of a pan versus time during the firing, heat efficiency, and the time of ceasing ember. The results showed that the cooking temperature (>180 oC) was reached after 35-65 minutes. The cooking temperature lasted for 4 hours, heat efficiency of 25.5 % was about optimum, and the time of ember ceasing was 19-33 minutes
