“…This study expands upon previous work in which the effects of fuel type, ,, fuel moisture content, , fuel particle size, ,− primary air flow rate, ,,, ratio of secondary to primary air flow, ,, secondary air inlet area, , chimney sections, and operating mode , on gasifier cookstove performance were investigated experimentally. A comprehensive evaluation of performance, including measurements of CO emissions, PM 2.5 emissions, useful power output, producer gas composition, and fuel bed temperatures, was completed.…”
