| 摘 要： | 本文以土耳其SILOPI 2#机电除尘器为工程分析对象,对燃煤电厂电除尘器船型灰斗内的粉尘在停机后的温度变化情况进行分析计算和有限元模拟,通过粉尘随时间的温度变化数据判断粉尘的凝结情况,得出该项目在最低气温-9.3℃环境下,119小时内船型灰斗不会因粉尘凝结而发生严重堵塞情况,模拟结果与实际一致。本文为工程上电除尘器因故停机的检修提供时间参考。

| Abstract: | This paper analyzed the SILOPI 2 ESP in turkey and gave a finite element modelling on the coal ash which is in the coal-fired power plant ESP ship hopper after an outage. It can judge whether the coal ash was congealed from the temperature variation of coal ash over time. For this project, the coal ash will not be congealed seriously in 119 hours after an outage when the local minimum environment temperature is -9.3℃ and it is as well as practical experience. This paper gave a time reference for emergency maintenance of ESP. |
