本文提出了一种提高燃煤沸腾炉燃烧效率的新方法。该工艺的要旨是:大部分煤的细粉所组成的煤水混合物在投入沸腾炉后能够形成具有一定强度和耐磨性的凝聚团。利用煤水混合物的凝聚结团特性能够增加煤中细粉在沸腾炉内的停留时间,从而大大减少扬析损失,该方法配之以异重流化床技术后,形成了一个完整的工艺。 This paper presents a new method to improve the combustion efficiency of coal-fired boiler. The essence of this process is that the coal-water mixture composed of most of the fine coal powder can form agglomerates with certain strength and abrasion resistance after being put into a boiling furnace. Utilizing the agglomeration characteristics of the coal-water mixture can increase the residence time of the fines in the coal in the boiling furnace and thus greatly reduce the loss of the yanchang. This method, coupled with the heavy-duty fluidized bed technique, forms a complete process.
