Research on Mechanical Engineering with the Design and Implementation of Thermal Power Boiler Soot Blowing Control System

Abstract:

Ash deposition and slagging on boiler heat exchange surfaces is a common phenomenon in fossil fuel fired power plants. In this dissertation, author focuses on the building of soot blowing control system and all of the work is based on a 300MW boiler. This dissertation introduces the endangerment of soot deposition on boiler heat exchange surfaces. In order to reduce the loss due to fouling of the heat exchange surfaces and improve the economic efficiency of the boiler. In this dissertation, author finds the reason about the fouling form and makes analysis on the damage about the soot to thermal power boiler. On the other hand, author make design and implementation of the thermal power boiler soot blowing control system including hardware system design and software system design, and it will be the fundament of soot blowing optimization. The hardware can connect the equipment about the boiler together, and it is the foundation of the control system for thermal power boiler. Based on the data from DAS of power plant and using heating balance theory, this software system puts forwards some graphical user interfaces and that can configure the setting data and monitor the information about thermal power boiler. In this dissertation, author will design and realize the control system about thermal power boiler.
