摘要：

Ash handling system of Coal-fired power plant is a advanced, economic, environmental science and technology. As the requirements and limitations of environmental protection. water resources and others, positive pressure pneumatic ash handling is widely used as ash handing method in China's coal-fired power plant. In this paper. Changchun High-tech thermal power plant unit 2 25Mw Ash delivery system is taken as object describing the configuration and project delivery process of pneumatic ash handling system, according to the control performance requirements of the ash handling system unit designed to using Siemens S7-200 type PLC for the control core of dual-machine redundant automatic control system to achieve the ash system control requirements and the main function, while in the PC,software Wincc6.2 used to control PLC running to achieve a successful running of equipment data collection, centralized operations, real-time monitoring, data storage, fault alarm functions, improving the system's control and management capabilities. Reduced the labor intensity of running, saving the cost of maintenance.
