The present invention relates to the field of biomass based cooking and heating systems. More specifically the present invention is directed towards a clean combustion for both process heating and cooking applications having emission characteristics and thermal efficiency at par with the LPG stove. We have achieved the emission factors (kg/kg-fuel) of PM2.5 as 1/3rd and carbon monoxide (CO) as 1/11th of LPG stove, when tested using the same testing protocols (BIS). The lowest emission of PM2.5 and CO is the most important criteria for any cooking and heating device and the present model is superior to those (>500 models of improved cookstoves) available, globally.
