摘要：Approximately 70-80% of the total energy used in villages is consumed for domestic cooking and 80-90% ofthe domestic energy needs are met through firewood, cow dung and agricultural crop wastes. The bio fuelsare being burned in low efficiency traditional cook stoves. The environment within the house is polluted bythe smoke emitted from the traditional cook stoves causing ill effect on health of women and children. Toalleviate this problem, a number of double pot improved cook stoves (ICSs) have been developed for ruralpeople. Experiments were conducted on different models of cook stoves viz. traditional cook stove, Sukhad,Udairaj and improved Udairaj models to find the thermal efficiency, power rating and specific fuel consumptionby conducting water boiling test. Udairaj cook stove was found to have the highest thermal efficiency of23.4%, whereas traditional cook stove was found to have lowest thermal efficiency of 15.4% among the cookstoves tested. Uadairaj and improved Udairaj cook stoves were found to have similar power rating andlowest specific fuel consumption in the range of 0.811 kw to 0.849 kw and 1.232 kg/kwh to 1.225 kg/kwhrespectively whereas traditional cook stove was found to have lowest power rating of 0.559 kw and highestspecific fuel consumption of 1.799 kg/kwh.
