本文介绍了５４室敞开式焙烧炉的设计技术性能和工艺特点．结合生产实践经验对该炉的热平衡进行了计算和分析．对采用煤气焙烧技术也进行了探讨，提出增开第四火焰系统可使焙烧炉增产近１００００ｔ／ａ．火焰移动周期从设计的３７ｈ延长为４０～４８ｈ，进入净化设备的烟气温度从过去的４０～６０℃提高到７０～１００℃．烟气中的沥青焦油含量经测定低于国家排放标准，湿法三级净化设备的洗涤塔和电收尘器的运转率提高５０％．焙烧温度的提高，使焙烧后的阳极炭块质量明显提高．第四火焰系统的点火试验成功，解决了我厂由于焙烧炭块不足而直接影响年产铝锭５万吨的问题；初步解决了由于烟气温度低而使净化设备长期运转不正常的难题；初步计算年增效益达２００万元，同时也为我国同类型的敞开式焙烧炉的增产节资闯出了一条新路．
This article describes the design of 54 chamber open roaster technical performance and process characteristics. The heat balance of the furnace was calculated and analyzed with practical experience. The use of gas roasting technology is also discussed, proposed to increase the fourth flame system can increase the roaster firing nearly 10000t / a. The flame movement period is extended from 37h to 40 ~ 48h from the design, and the flue gas temperature entering the purification equipment is increased from 40-60 ℃ to 70-100 ℃. Asphalt tar content in the flue gas is lower than the national emission standards, and the operation rate of the scrubber and the electrostatic precipitator of the wet-type tertiary purification equipment is increased by 50%. The roasting temperature is raised, so that the quality of the fired anode carbon block is obviously improved. The successful ignition test of the fourth flame system solved the problem that our factory directly affected the annual output of 50,000 tons of aluminum ingots due to the shortage of roasting carbon blocks. The preliminary solution to the problem of long-term operation of purification equipment due to the low temperature of flue gas was not solved. Preliminary calculation of the annual benefit of 2000000 yuan, but also for the same type of open roasting furnace to increase production and expenditure to break a new road.
