| 中文摘要: |
| 分解炉内分级燃烧自脱硝技术是水泥生产线降低NOx排放和脱硝氨水用量的重要手段。本文介绍了分解炉内深度自脱硝的技术优势，并将该技术应用于一条7 000 t/d的熟料生产线。结果表明，在线分解炉内燃料的分级燃烧，可通过创造较大的还原区域，大幅度降低分解炉出口的NOx浓度，分解炉出口72 h NOx浓度（标况下）均值为247.2 mg/m3（@10%O2），此外，分解炉出口NOx浓度降低有效减少脱硝总氨水用量，节省了企业的运行成本。 |
| 英文摘要: |
| In-furnace staged combustion self-denitration technology is a crucial method for reducing NOx emissions and decreasing the usage of denitration ammonia water in cement production lines. This article highlights the technical advantages of deep in-furnace self-denitration and applies this technology to a 7 000 t/d clinker production line. Practical application results demonstrate that staged combustion of fuel within the online calciner creates a substantial reduction zone, significantly lowering the NOx concentration at the calciner outlet. According to data measured by the flue gas analyzer at the calciner outlet, the 72 h average NOx concentration (under standard conditions) was 247.2 mg/m³ (@10% O2). Additionally, the reduction in NOx concentration at the calciner outlet effectively decreases the total consumption of denitration ammonia water, thereby reducing the operational costs for the enterprise. |
