本文介绍了MPY型煤粉平焰烧咀在可锻铸铁退火炉上的工业性试验应用情况。二台MPY—100煤粉平焰咀安装在炉顶、使整个退火炉内供热均匀、大大提高了退火质量。文章详细介绍了煤粉平焰烧咀的使用情况。结果表明:MPY型煤粉平焰烧咀点火性能良好、火焰稳定、燃烧充分、节能效果较好、每吨铸件煤耗已从原来的450公斤标煤/吨铸件降低到262公斤标煤吨铸件以下。马鞍山钢铁学院试验组和昊县马铁厂合作在该(?)十吨可锻铸铁煤粉退火炉上进行MPY型煤粉平焰烧咀的工业性试验、取得了较为满意的结果。
This article describes the application of MPY pulverized coal burner in malleable iron annealing furnace industrial test. Two sets of MPY-100 coal flat flame Tsui installed in the roof, so that the entire annealing furnace heating evenly, greatly improving the quality of annealing. The article details the use of coal powder flame burner. The results show that the MPY coal-fired flame burner has good ignition performance, stable flame, full combustion and good energy-saving effect. The coal consumption per tonne of castings has been reduced from 450 kg / ton of standard coal to 262 kg / . The Maanshan Iron and Steel Institute pilot group and the Haoxian Iron Works cooperated to carry out MPY pulverized coal co-firing pilot tests on the (?) Ten-ton malleable cast iron pulverized coal annealing furnace with satisfactory results.
