干排渣机负压输送系统的优化及应用

Optimization and application of negative pressure conveying system of dry-type slag extractor

针对干排渣机后续输送系统中的负压输渣系统运行成本高、输渣管道磨损严重等问题,分析了产生问题的原因,提出了优化方案。对比了优化前、后的负压输渣系统在2台相同火电机组上的使用情况,结果表明,优化后,负压输渣系统能有效降低运行成本,减少系统的维护量,提高输送效率。

Aiming at the problems of the high operation cost,the serious abrasion of the slag conveying tubes and others of the negative pressure slag conveying system existed in the follow-up conveying system of dry-type slag extractor,the reasons of the problems were analyzed,and the optimization scheme was proposed.The operation situation of the optimized negative pressure conveying system was compared with that of original negative pressure conveying system used in similar fossil fuel power unit,and the result shows that the optimization of the negative pressure conveying system can reduce the operation cost effectively,decrease the system maintenance working load and improve the conveying efficiency.
