【摘要】 为满足燃烧脱硫研究的需要,该文探讨了链条炉内温度及气氛分布的规律。研究发现:在链条炉排中部的火床煤层和燃烧烟气空间内,温度分布沿高度方向均先升高后降低,整体呈现双峰规律。煤层上部烟气中的SO2浓度沿炉排移动方向亦先升高后降低,在炉排中部剧烈燃烧区达到最大。将添加剂喷射至炉膛烟气空间比掺混在火床煤层内部具有更好的脱硫效果。更多还原

【Abstract】 To meet the demand of research ondesulfuriza-tion during coal combustion, the characteristics of tempera-ture and gas composition distribution in the traveling grate furnaces are discussed in this paper. It is found that both temperatures of the coal bed and the combustion gas firstly rise and then decline in the height direction, forming twotemperature peaks on the whole. The SO2 concentration in the combustion gas above the coal bed also firstly rises, thendeclines along the traveling grate and reaches maximum near the midpoint of the grate. Injecting the sorbents into thecombustion gas can achieve higher sulfur removal efficiency than blending the sorbents with the coal.更多还原
