Stainless steel wire mesh,, thermal efficiency,, vertical port cooking stove,, pollutant emission.Abstract
The objective of this research is to improve the thermal efficiency of vertical port gas stove, which consumes the highest amount of Liquefied Petroleum Gas (LPG) not excess 5.78 kW, in accordance with Thai Industrial Standard 2312-2549 (TIS. 2312-2549). In this study, effect of porous media made from stainless steel wire mesh installed on stove head on the thermal efficiency of the stove was investigated. The thermal efficiency and pollutant emission of the gas stove were investigated by boiling test based upon TIS 2312-2549. Moreover, effect of firing rate and container sizes on thermal efficiency and pollutant emission was also studied. From the experimental results, it was found that mesh size of 16 mpi was the most suitable caused the highest thermal efficiency. The firing rate increased, the thermal efficiency decreased. However, the thermal efficiency increased when the container size increased. The maximum thermal efficiency of 77.06 % was obtained from the wire mesh of 16 mpi, the pot of 32 cm and the firing rate of 0.89 kW. The CO and NOx emission were not more than 600 ppm and 80 ppm, respectively, in all cases.
