上燃均衡供氧式生物质成型燃料炊事炉的设计与性能测试
|
摘要
为提高农村用能效率,依据生物质燃烧特性和热工计算标准,设计上燃均衡供氧式生物质成型燃料炊事炉。确定炊事炉的主要设计参数,构建相互独立的螺旋式分级配风系统及灰仓与风管相结合的自然进风系统,并对炊事炉的性能进行测试。结果显示炊事炉热效率为40.25%,炊事火力强度为3.32 kW,烟尘、CO、SO_2、NO_x等烟气污染物排放均符合国家相关标准,可保证成型颗粒燃料的充分燃烧,提高燃烧性能。
In order to improve the energy efficiency in rural area,a top combustion and balanced supply of oxygen cooking stove using biomass briquette fuels was designed based on combustion characteristics of biomass and thermal calculation standards. The main parameters of the cooking stove were designed,and the independent spiral grading air distribution system and the natural ventilation system combining ash silo and air duct were built. The performance of cooking stove was tested. The results show that the thermal efficiency of cooking stove is 40.25%,and the fire intensity for cooking is 3.32 kW and emission indexes of flue gas,such as CO,SO_2,NO_x etc. are in compliance with relevant national standards. The cooking stoves ensure the full combustion of the formed pellet fuel and improve the combustion performance.
