生物质颗粒燃料炊事炉的性能

Performance of cooking stoves with biomass pellet fuel

生物质颗粒燃料作为一种清洁燃料,需要设计能使其高效、清洁燃烧的特殊炉具。该文介绍了3种生物质颗粒燃料炊事炉原始样炉的热效率、燃烧特性、烟气中污染物浓度等测量结果。试验过程中以玉米秸秆颗粒为生物质颗粒燃料,并参照国家标准GB4363-1984《民用柴炉、柴灶热性能测试方法》,采用烧水试验方法。试验结果显示:这3种炊事炉都可以清洁地燃烧用农业、林业固体剩余物制成的颗粒燃料;其中带有微型风机供风的炊事炉根据试验结果改进后的产品炉的热性能和大气污染物排放水平均满足北京市地方标准DB11/T540-2008《户用生物质炉具通用技术条件》规定的指标和限值。

Biomass pellet fuel as a clean fuel,it needs to design special stoves to make them burning more efficient and cleanly. It will present three kinds of pellets-fired original stoves for cooking of farmer households in this paper.Performances of the stoves,such as thermal efficiency,combustion characteristics,and pollutants in flue gas are experimentally studied.The biomass pellet fuel is corn stalks in the course of the trial.The test procedure is according to the national standard GB4363-1984 which method is water heating test.The experimental results show that these stoves can use the pellet fuel which is made from the agricultural and forest residues more efficiently and clearly.Then,the thermal efficiency and pollutants in flue gas of the new cooking stove,which is improved in accordance with the results of the cooking stove that with a mini-fan for the wind,satisfy the level and limits of the local standard in Beijing DB11/T 540-2008.
