自贡轻机厂在七十年代初曾相继生产过 QJP25—4.6/13——Ⅰ型、WGZ12/13——Ⅰ型喷射炉,同期天津轻机厂生产过40——6.5/13型喷射炉。这些炉子经有关用户纸厂运行以来,已陆续超过十万小时的使用寿命.近几年来上述各型喷射炉用户来厂要求大修换管、更换省煤器及其它部件。我厂为用户大修喷射炉的技术服务工作中重视了改造设计。如83年5月,广西贵县糖厂喷射炉大修更换水冷壁管时,我厂对设计图纸进行了修改,在标高
Zigong Light Machinery Factory in the early seventies have been produced QJP25-4.6 / 13 - Ⅰ type, WGZ12 / 13 - Ⅰ-type injection furnace, Tianjin Light Machinery Factory over the same period produced 40 - 6.5 / 13-type injection furnace. These furnaces have already exceeded the service life of one hundred thousand hours in succession by the users of relevant paper mills. In recent years, the users of these types of injection furnaces have come to the factory to require overhaul tubes and replace economizers and other components. I plant for the user overhaul injection furnace technical services in the emphasis on the transformation of the design. As of May 83, Guangxi Guixian sugar factory overhaul spray tube furnace replacement water wall tube, I plant on the design drawings were modified at the elevation
