| 摘 要： | 煤粉浓度对煤粉气流着火及燃烧稳定性的影响较大。结合具体的燃烧器，建立了稳焰船回流区热平衡模型，由此可近似求出加装稳焰船燃烧器后，在一定工况下煤粉气流燃烧稳定所需的最低煤粉浓度。利用本模型对某电厂１０２５ｔ／ｈ炉进行实例计算，与实验结果基本一致。

| Abstract: | Pulverized coal concentration in primary air stream has an important effect on ignition and combustion stability. The heat balance model in recirculation region of flame-stabled boat is established with a specific combustion device. The minimal pulverized coal concentration for combustion stability under certain conditions is approximately obtained. Based on this model, a practical calculation on 1025t/h utility boiler is implemented and its prediction is consistent with the experiment result. |
