Design and performance test of multi-function stove for biomass fuel

In order to solve these problems, combined with the living habits of the rural residents in the northern region, design a biomass multi-functional stove in accordance with the relevant national standards. This design based on the design principles of biomass fuel stove, corn straw briquette fuel was used. The main structure consists of air duct, components of grate, furnace, Cupping, circumferential water box, water jacket, chimney, feeding device, etc. The chimney cross-sectional area F is 0.0072 m super(2) and white metal chimney of circular cross-section of diameter 10cm was used. Automatic feeder was used and feed rate is maintained at 2.5 to 3.0 kg/h, to be completed all night (12 h) of heating demand (heating and warming kang). The integrated thermal efficiency was 78.55%, thermal efficiency is higher than other stoves, it has good energy saving effect. Flue gas emission indexes were lower than the national standard.
