Abstract: Millions of people around the world are using biomass fuels to satisfy their energy requirement for cooking. Two pot raised mud Improved Cookstove (ICS) is one of the most promoted cookstoves in Nepal. There is a need to study the effects of different parameters on two pot raised mud ICS for its optimum performance. The goal of this work is to study the effect of variation of different parameters for two pot raised mud ICS and identify parameters for optimum performance. Power test for cookstove, specially focusing thermal efficiency has been performed by changing different parameters. Effect of varying fuel feeding rate, chimney height, opening area of air fuel inlet, inlet area of interconnecting tunnel, combustion chamber height, grate height and insulating material on thermal efficiency has been studied and cookstove has been modified for its optimum performance. The thermal efficiency of optimized cookstove, using 2 cm grate and insulation has shown an increase of 6.70 from 18%.
