摘　　要：采用生物质成型燃料专用妒灶为燃烧设备,以玉米秸秆成型燃料为试验燃料,研究了过量空气系数、炉膛温度、燃料层厚度、燃料粒径对燃料结渣的影响.结果表明,生物质成型燃料炉灶工作时的最佳工况为过量空气系数α_(lt)为1.5,最佳工况下结渣率为3.5%,具有轻微结渣性.生物质成型燃料在炉灶的燃烧中,结渣率是随着温度的升高、炉膛α_(lt)的增大、燃料层厚度的增加而有不同程度的增加.Using the biomass briquette special-purpose fire pivot as the fuel-burning equipment, and the corn stalk formation fuel as experiment fuel, the influences of the excess air coefficient, furnace-tank temperature, the thickness of fuel layer and the diameter of fuel on the slagging rate are studied. The result shows that, the best working conditions for the biomass briquette combustion stove is alt = 1.5, the slagging rate is about 3.5% under the best working conditions, it has the slight slagging characteristic, forming biomass briquette fuel combustion in the stove, the slagging rate is increasing correspondingly with the raising of temperature, the riging of the excess air coefficient and the increasing of the fuel layer thickness.
