华电淄博热电机组扩建工程除灰渣系统设计

Design of Ash Handling System for Huadian Zibo Thermoelectricity Project

对华电淄博热电机组扩建工程2×330 MW抽凝式燃煤供热发电机组的除灰渣系统进行了设计总结,简要介绍了此工程除渣系统和除灰系统的设计特点,并对安装和运行过程中暴露出来的设计问题进行了剖析。本工程除渣系统采用风冷干式除渣机一步上仓方案,取消了斗式提升机,降低了设备造价,运行更加稳定,也相应降低了检修维护费用;除灰系统采用传统的正压浓相气力输送系统,同步设置分选系统,对粗细灰进行分离,更有利于综合利用。

The design of the ash handling system for Huadian Zibo thermoelectricity 2 ×300 MW project was Summarized, the ash handling system was introduced, and the problem in the installation and operation phase was analyzed. The air cooled bottom ash handling system was used for this project, cancelled the bucket elevator, the cost of the equipment was reduced and more stable operation, also reduced maintenance casts. Positive pressure pneumatic conveying system was used for fly ash handling system, sorting system was set simultaneously, the crude ash and the fine ash was separated and was better use for comprehensive utilization.
