Design, Manufacture, and Optimization of a Micro-Gasifier Biomass Cook Stove

In international development programs on improvement of energy supply for cooking in remote regions, where people are dependent on wood as the sole fuel resource, biomass cook stoves have a remarkable place. The thermal efficiency of such stoves are up to 3 times of those of traditional open fire stoves. In this research, a biomass cook stove was manufactured and evaluated according to the emission and performance test protocol. The fire power of the stove was 1.4 kW, and flaming duration by feeding 400 g of pistachio shell was recorded to be 26 minutes. In order to improve the pyrolysis vapor combustion process, a damper was embedded in the stove, and also the outer wall of the stove was isolated by using a ceramic layer. Results showed that the control index was improved by three folds. Also, burning duration increased up to 57% and the emission of carbon monoxide was found to be in the permissible range.
