Biomass is used for cooking purpose from several centuries. In India, simple rice husk stoves are in use from a long time which is cheap but it emits tiny, rich in silica ash particles in the flue gas. It causes health problems to the user. In this project, an attempt has made to design and fabricate a user-friendly, eco-friendly and economical rice husk gasifier stove. New rice husk gasifier stove generates luminous blue flame having thermal efficiency around 29% similar to LPG stove. This stove will be helpful for people in rice growing rural areas where abundant quantity of rice husk is available. The main objective of this work is to help rural families for whom LPG stove is not affordable and where indoor air pollution is common due to traditional cooking methods. This gasifier has ability to consume 3.5 kg of rice husk per batch and it operates 60 minutes to 80 minutes. By using this stove, one time meal for a family of 6-7 peoples can be cooked.
