1. The pelletizing and lime technology based on using burning technology of the low heat value blast furnace gas and the grate-kiln process is on the leading place in China. 公司依靠独创的低热值高炉煤气培烧技术，采用链篦机-回转窑-环冷机工艺设计开发的冶金球团、石灰生产技术，属国内领先水平。
2. Based on the machinery technical improvement on KZL2-7 type automation boiler grate, the trouble ratio in heating period is reduced, the repair time is shorted and benefit is obliouse. 通过对岭北煤矿型号为KZL2—7的自动化锅炉炉排进行机械技术改进，降低了采暖期故障率的发生，缩短了故障维修时间，效益显。
3. Through gasifier calibration, the feed distribution along the cross sections, the falling down of dregs, and the influence of grate structure to the gasification of fuel layer can be understood. 通过煤气炉冷炉测定，了解煤气炉内原料粒径沿床层截面分布情况，炉渣下降情况，炉箅结构对燃料层气化的影响等物料性状。
