摘要
固体燃料是农村最主要的能源之一,为研究农村地区典型固体燃料的燃烧特性,选取包含木头、玉米秸秆、木质颗粒和玉米秸秆颗粒在内的四种生物质燃料和包含烟煤块、烟煤煤球、兰炭和兰炭蜂窝煤在内的四种煤炭燃料进行热动力学分析。结果表明:八种燃料主要失重过程均发生在挥发分析出燃烧阶段和焦炭燃烧阶段;生物质燃料在挥发分析出燃烧阶段的活化能大于焦炭燃烧阶段的活化能而煤炭燃料则相反。研究结果可为农村地区固体燃料加工技术和清洁炉具设计提供理论指导。
Solid fuel is one of the most important energy in rural areas, in order to study the combustion characteristics of typical solid fuels in rural China, four types of biomass fuels including wood, corn straw, wood pellets and corn straw pellets and four types of coal fuels including bituminous coal chunk, bituminous coal briquette, semi-coke and semi-coke honeycomb briquette were selected for thermodynamic analysis. The results showed that the main weight loss processes of the eight fuels occurred in the devolatilization and char combustion phases. The activation energy of biomass fuels in the devolatilization phase are greater than that of char combustion phase, while that of coal fuels are the opposite. This study provides useful information for solid fuel processing technology and clean stove design in rural areas.
