基于DCS系统350MW超临界供热机组吹灰系统设计

Design of Blowing System Based on DCS System in 350MW Supercritical Heating Unit

本文介绍了超临界供热机组锅炉吹灰系统在和利时DCS系统中的设计方法,介绍了长吹、短吹、空预器吹灰器工作流程。给出了整个吹灰系统程序控制的设计思路。归纳了运行中存在的问题并给出处理建议,供有关人员在设计及现场调试逻辑组态时参考。

This paper introduces the design of the boiler blowing system of the supercritical heating unit based on Hollysys DCS system. Work flow of long blowing, short blowing and air pre-heater blowering is introduced. The design ideas of the whole process control are given. Problems in operations are summarized and suggestions are given for reference in design and field debugging logic configuration.
