Abstract: In order to solve the energy shortage problem in rural area of China, biomass briquette stove was designed according to the general cooking habits of the current rural life and the strict computation. The results indicate that the thermal efficiency was 40.6%, it was 15 minutes form fire point to the combustion, and intense combustion sustained 62 minutes. The stove can conform the current rural life. The combustion of the biomass briquette stove was stable, fewer pollutants, which would provide stable energy in cooling system.
