“…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.…”

Development of biomass cookstoves that reduce emissions of CO and PM2.5 by more than 50% and 95%, respectively, compared to a three-stone fire has been promoted as part of efforts to reduce exposure to household air pollution (HAP) among people that cook with solid fuels. Gasifier cookstoves have attracted interest because some have been shown to emit less CO and PM2.5 than other designs. A laboratory test bed and new test procedure were used to investigate the influence of air flow rates, stove geometry, fuel type, and operating mode on gasifier cookstove performance. Power output, CO emissions, PM2.5 emissions, fuel consumption rates, producer gas composition, and fuel bed temperatures were measured. The test bed emitted <41 mg·MJd–1 PM2.5 and <8 g·MJd–1 CO when operating normally with certain prepared fuels, but order of magnitude increases in emission factors were observed for other fuels and during refueling. Changes in operating mode and fuel type also affected the composition of the producer gas entering the secondary combustion zone. Overall, the results suggest that the effects of fuel type and operator behavior on emissions need to be considered, in addition to cookstove design, as part of efforts to reduce exposure to HAP.

“…Thus, gasifiers are equipment that enables the thermochemical conversion of solid fuel to gaseous fuel. Drying at a temperature greater than 100°C, Pyrolysis at a temperature greater than 300°C, and combustion of wood gas are all steps in this process [2]. When fossil fuels were hard to come by in Europe during the Second World War, the concept of gasification became particularly important.…”

This study aims to adapt and evaluate an updraft biomass gasifier stove using sawdust biomass. It was a cylindrical gasifier having a diameter of 32.5cm*40cm height and a rectangular box-like base that served as a set and had a primary air hole of 20cm*6cm sliding type door. Fuels made from renewable biomass might easily take the place of fossil fuels in a variety of energy-using applications with favorable environmental effects. Gasification is a method of converting biomass energy into a fuel that potentially replace fossil fuels in the production of high-efficiency electricity. The future of energy is looking promising for biomass energy as one of the most important renewable energy sources. This work has been carried out to adapt, construct, and test an applicable biomass gasifier stove. This is for producing producer gas from locally available biomass fuel. The gasifier was constructed and tested on Water Boiling Test (WBT). The test was run using sawdust as feeding fuel. Various factors, including primary and secondary air inlets, operation, fuel type, and manufacturing materials and techniques, were presented and assessed. The updraft gasifier stove was evaluated at a biomass feeding rate of 0.5kg per batch. The results obtained from this study show a combustion efficiency of 84.2% and a thermal efficiency of 30.6% respectively. Therefore, the outcome could offer contemporary energy services for necessities and useful uses.

“…Globally, more than 2.5 million deaths are attributed to smoke released from cooking related activities while meeting the cooking energy demand (IEA, 2020). Currently, many researchers are working to develop a reliable, highly efficient cookstove with low emissions of airborne pollutants (Birzer et al, 2013, Tryner et al, 2016, Tryner et al, 2018, Tyagi 2022.…”
