To control pollutant emissions from the combustion of both domestic stoves and small-capacity industrial boilers, an artificial solid fuel called biobriquette has been developed. It is manufactured from a mixture of coal, biomass (sawdust), and desulfurizer under a high compression pressure. In this study, the combustion experiments were performed to elucidate the ignition and combustion characteristics of biobriquette. Comparisons were made between coal briquettes and biobriquettes for their combustion efficiencies and pollutant emissions in existing domestic stoves. Byproduct in the gas welding industry was used as a new desulfurizer in the biobriquette, and its desulfurization characteristics were studied. The experimental result shows that the biobriquette has a lower ignition temperature and a higher combustion efficiency than the coal briquette. The new desulfurizer was found to be more effective in desulfurization than the other two desulfurizers, limestone and scallop shell. It is also found that ...
