液态排渣炉在运行中,经常碰到的问题之一是炉底排出铁水,通称析铁。析铁对人身及设备的危害很大。从1958年以来电力部西安热工研究所、青岛发电厂、豆坝电厂等单位对防止炉底析铁做了不少工作。本文是在过去工作的基础上做的总结和分析,供今后改进运行和深入研究作参考。一、析铁的危害 1.由于析铁,大量铁水从渣口流入渣井。高温的铁水与水反应,释放出氢气,易引起爆炸。国内早期在一台35吨/时炉上,曾发生过氢气爆炸造成人身伤亡事故。
Liquid slag furnace in operation, often encountered one of the problems is the discharge of molten iron bottom, known as the analysis of iron. Analysis of iron on the human body and equipment is very harmful. Since 1958, Xi’an Institute of Thermal Power, Ministry of Power, Qingdao Power Plant, Bean Dam Power Plant and other units to prevent the bottom of iron precipitation done a lot of work. This article is based on past work done summary and analysis for future improvements in operation and in-depth study for reference. First, the dangers of the analysis of iron 1. As a result of iron, a large number of hot metal from the slag mouth into the slag well. High temperature hot metal and water reaction, release of hydrogen, easy to cause an explosion. Domestic early in a 35 tons / hour furnace, there had been a hydrogen explosion caused personal injury.
