Performance of cooking stoves with biomass pellet fuel

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.
