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.
