煤气

This thesis is theoretic and applicable to the gas mixing and pressuring station.

本课题对煤气混合加压站的控制具备一定的理论和应用价值。

The main works of this dissertation are shown as follows:(1) We analyzed the study actuality and the meaning of the control system for pressurizing the mixed coal gas.

本文完成的工作如下：(1)分析了混合煤气中继加压系统控制的国内外现状及其意义。

The system — the first of its kind in the world — does not predict quakes, but officials say it can give people enough time to get away from windows that could shatter, or to turn off ovens and prevent fires from razing homes.

这个系统，在世界上尚属首创，并不预报地震。但官员们说它可以给民众足够的时间将可能在地震中粉碎的动地从窗户上扔出去，或者将煤气关上，从而防止大火将他们的家给烧毁。

The place reeked with coal fumes, sweat and the smoke of cheap cigarettes.

天极冷，小茶馆里的门窗都关得严严的，充满了煤气，汗味，与贱臭的烟卷的干烟。

Combined with investigation results of the furnace body erosion before relining, this paper analyzes the cause of production problems appeared in the first campaign life of the blast furnaces. Because of the existence of design shortcomings in large cooling block and bosh cooling stave, it resulted in poor furnace performance, such as stronger peripheral gas flow and irregular profile. The quick rise of bottom temperature of No.7 BF was caused by the penetration of molten iron into the joint of bottom carbon block, wheresas the quick rise of bottom temperature of No.6 BF was due to gas fleeing through the furnace bottom.

结合大修前炉体破损情况，对这两座高炉第一代炉役生产中出现的问题进行了调查研究。7号高炉大型模块和炉腰冷却壁设计上存在不足，引起高炉边缘气流发展，操作炉型不合理，炉况不顺；7号高炉炉底温度偏高是炉底炭砖渗铁造成的，6号高炉炉底温度偏高是炉底串煤气所致；7号高炉铁口失常的主要原因是铁口组合砖损坏严重和该部位炉壳开裂。
