왕겨의 HEAT FLUX별 연소특성에 관한 연구

초록

Biomass burning is a source of greenhouse gases, carbon dioxide, methane, and nitrous oxide. Under the ideal conditions of complete combustion, the burning of biomass produces carbon dioxide and water vapor. Since complete combustion is not achieved under any conditions of biomass burning, other carbon species, including carbon monoxide, methane, non-methane hydrocarbons and particulate carbon are produced. In this study, we analyzed the combustion characteristics of rice-husk, such as heat release rate, smoke production rate, the percentage variation of CO and CO2, oxygen consumption rate, and mass loss under different heat fluxes(5, 10, 15, 20, 25, 30, 40 and 50kW/m2). As a result, under 20kW, non-flaming combustion is occurred so that the productions of CO, CO2 and total smoke release are higher than the others(25, 30, 40, 50kW/m2). The production of CO2 in the range of 1.57～3.61kg/kg is 10 times higher than compared to the results of another cereal waste burning conducted by Ortiz de Zarate et al(2000). It means that open burning of rice-husk could promote the emission of CO and CO2 to the atmosphere and effect to the global warming and global climate change.
