Two-third of the world population and Indian population depends on biomass as their primary source of energy for cooking. It is worrying that, majority of those people still use the traditional cook stoves which have low thermal efficiency, high CO and particulate matter emission. Few innovations have happened in biomass cook stove in light of the experience of the user and the thermal efficiency has improved to some extent. However the harmful emissions and health hazards are still remaining. The decreasing reliability on fossil fuels, increase in cost of LPG and high GHG emission is setting an alarm to go for efficient biomass cook stoves. Indian government has setup an initiative through National Biomass Cook stove Program promoting the vendors who manufactures improved cook stoves as per the norms. This research is aimed at identifying an improved cook stove available in market and evaluating it with two different fuels conducting performance evaluation of an advanced micro gasifier cook stove which would cater to the requirements of the society and environment. TERI SPT-060 was the cook stove selected based on MNRE criteria for the evaluation. Juliflora wood and Coconut shell are the two fuels shortlisted for the evaluation. WBT 4.2.3 testing protocol was used for the evaluation. The evaluation results clearly states that coconut shell has got better thermal efficiency and Fire power. However juliflora loses marginally only and due to its abundance could easily match with coconut shell as fuel. © 2015 Journal of Chemical and Pharmaceutical Sciences.
