我厂原有两座建厂初期自行设计的马弗型燃煤搪烧炉(窑),由于其结构不够合理,运行中热效率低、烧成烘干温度不稳定、烘干与烧成能力不配套,导致了持续多年的低产低质高能耗生产。为此,1990～1991年我们结合大修对两座马弗炉分两期实施了技术改造。 一、改造措施 1.改革燃烧方式。设计制造螺旋加煤机一套,改原来的间断手工投煤为连续机械加煤,促进了煤炭的燃烧完全。
The two original coal-fired burners (muffles) designed by our factory in the early days of their establishment, due to their improper structure, low thermal efficiency during operation, unstable baking and drying temperature, poor drying and firing capacity Supporting, leading to many years of low-yielding low-quality high-energy production. To this end, 1990 ~ 1991 we combine the overhaul of the two muffle furnace in two phases of the implementation of technological transformation. First, the reform measures 1. Reform burning method. Design and manufacture of a set of spiral stoker machine, change the original intermittent manual coal injection for continuous mechanical coal, and promote the combustion of coal completely.
