| 中文摘要: |
| 本文基于多条水泥熟料生产线热工标定数据与运行工况，研究煤矸石作为原料配料、燃料入分解炉及冷却机投料三种方式对烧成系统的影响。结果表明：原料配料可降煤耗但易致 C1 分离效率下降、系统积料；燃料入炉能节约成本，炉容不足时易燃烧不完全；冷却机投料热利用率达 68.6%，可提升风温。 |
| 英文摘要: |
| Based on thermal calibration data and operating conditions from multiple cement clinker production lines, this paper investigates the impact of raw material proportioning, fuel feeding into the decomposing furnace, and cooling machine feeding on the sintering system. The results indicate that raw material proportioning can reduce coal consumption but may lead to a decrease in C1 separation efficiency and system material accumulation; fuel feeding into the furnace can save costs, but incomplete combustion may occur when the furnace capacity is insufficient; cooling machine feeding achieves a heat utilization rate of 68.6%, which can enhance air temperature. |
