【摘要】 本文介绍油煤混合燃料(COM)火焰在不同容积热负荷和不同过量空气系数下的辐射热流和黑度的试验研究结果。试验是在浙江大学的COM 燃烧试验炉中进行的。试验结果表明,沿着试验炉的长度方向,COM 火焰具有两个辐射热流峰值。在同样的过量空气系数条件下比较COM 火焰和重油火焰的黑度,发现在COM火焰根部的黑度小于重油火焰,但当火焰长度超过x/L=0.35以后,重油火焰黑度很快下降而小于COM 火焰黑度。更多还原

【Abstract】 The radiation heat flux and the emissivity of the coal-oil mixture(COM) under different volumetric burning intensity and coefficient of excess air are studied in a tunnel furnace.According to the results,it is found that there are two radiation heat flux peaks along the tunnel furnace.When burning with same coefficient of excess air,the emissivity of COM flame is smaller than that of the heavy oil flame,but beyond the section of x/L=0.35,the emissivity of heavy oil flameslips down more rapidly than that of COM flame does.更多还原
