| 摘 要： | 根据对链条炉的热力特性重要指标即炉排面积热负荷、炉膛容积热负荷的分析,认为链条炉低负荷运行时给煤量随负荷降低而减少。对层燃炉的燃烧特性以及从传热学角度对炉膛辐射热量进行分析,认为链条炉在低负荷运行时应采用薄煤层运行。结合链条炉实验测试,对分析进行验证,认为采用薄煤层、炉排快行进速度适用于链条炉的低负荷运行。

| Abstract: | According to the volume of the furnace heat load analysis of chain grate boiler , the amount of coal will reduce when the load of boiler reduces. According to the analysis of furnace radiant heat and combustion characteristics, the chain grate boiler should work with thin coal seam. Combined the experimental tests , the chain grate boiler should work with thin coal seam and fast travelling speed under low load operation. |
