Performance of Mohini-U, a single pot mud cookstove

Thermal analysis of Mohini-U, a single pot cookstove, at different wood burning rates has been reported in this paper. Heat losses due to radiation, convection and flue gas at different wood burning rates have also been presented. The results indicates that Mohini-U cookstove has a maximum efficiency of 27.56% at wood burning rate of 0.5 kg/h. CO/CO₂ ratio is also minimum (0.04) at this burning rate. The results further show that the efficiency is above 20% at wood burning rates of 0.75 kg/h and 1.0 kg/h. This clearly indicates that the performance of the cookstove is stable over a wide range of wood burning rates so as to satisfy the requirements of a wide spectrum of users in rural areas of the developing countries
