我厂自八七年四月开始采用热介质定向循环养护工艺生产电杆,并实现微机控制以来,收到了显著的经济效益。概括起来有以下几个方面。一、降低煤耗,节约能源我厂以前一直采用“波管直通式养护”,这种方法蒸汽浪费现象十分严重。采用定向循环新工艺后,蒸汽耗量大幅度下降。根据热平衡测定,热效率由原来的5.2％提高到54.2％,每根电扦的耗煤量亦由90kg Since April of 2007, our factory has adopted the hot medium oriented circulation maintenance process to produce poles, and has achieved remarkable economic benefits since it achieved microcomputer control. To sum up, there are the following aspects. First, reduce coal consumption, energy conservation I have been using the “wave tube straight maintenance,” this method of steam waste is very serious. With the new directional circulation process, steam consumption has dropped significantly. According to the heat balance measurement, the thermal efficiency was increased from the original 5.2% to 54.2%, and the coal consumption per electric furnace was also 90kg.
