摘　　要：生物质颗粒燃料是利用机械力将松散的生物质压缩或挤压成为密度较大、热效率较高、便于运输储藏的固体颗粒燃料,是煤的清洁替代能源,已广泛应用于工业和热力发电领域。针对生物质颗粒燃料的燃烧特性,设计了一种适用于农村地区的民用生物质颗粒燃料炊事炉具,并对其性能进行测试。测试结果显示,其热效率30.7%,升温速度24.4~25.7°C/min,炉膛内最高温度709°C,烟囱出口烟气最高温度286°C,烟气成分中O_(2)、CO的浓度范围分别为9.8%~17.4%、23~886 mg/m^(3),满足民用炊事炉具性能要求,可为农村民用生物质颗粒燃料炊事炉具的设计提供理论依据。Biomass pellet fuel is a solid pellet fuel that presses or squeeze biomass into large volume density,high thermal efficiency and easy transportation storage using mechanical force.It is a clean alternative energy of coal,and has been widely used in industrial and thermal power generation.According to combustion characteristics of biomass pellet fuel,a cooking stove for rural areas was designed,and its performance was tested.Test results showed that,thermal efficiency was 30.7%,heating rate was 24.4~25.7°C/min,the highest temperature in the furnace was 709°C,the highest temperature of chimney outlet flue gas was 286°C,and concentration range of O_(2) and CO in flue gas composition was from 9.8%to 17.4%and from 23 to 886 mg/m^(3),meeting performance requirements of civil cooking stoves.It could provide a theoretical basis for design of rural civil biomass pellet fuel cooking stove.
