沸腾燃烧锅炉飞灰的特点是带出量多而且含碳量高。如何回收这部分可燃物使之送入炉膛再燃烧,是提高锅炉燃烧效率的一个重要途径。这里我们研究了两种新的飞灰回收装置——微沸腾床气力输送槽和喷泉床气力输送方式。一、微沸腾床气力输送槽冷态试验装置是一只冷灰斗,其下部的落灰管与气力输送槽相连接。槽内设有多孔 Boiling combustion boiler fly ash is characterized by a large amount of output and high carbon content. How to recover this part of the combustible material into the furnace and then burn, is to improve the combustion efficiency of the boiler is an important way. Here we investigate two new fly ash recovery units - the Micro-Evaporation Bed Pneumatic Conveyor and the Fountain Bed Pneumatic Conveying. First, the micro-boiling bed pneumatic conveying tank cold test device is a cold gray bucket, the lower part of the ash tube and pneumatic conveying groove connected. Slot with porous
