The Design of Coal Blending System Based on Plc
|Title||The Design of Coal Blending System Based on Plc|
Through the application of the PLC, the traditional mode of the coal blending system is optimized and improved, from the manual blending to the auto control. The main goal of this project is to change the past blending system of traditional manual coal run, in order to enhance productivity, from the amount of coal on the coal source control, the solution to the problem of coal power plants, improving the efficiency of coal-fired power plant and economic benefits. The use of coal power plant now not singletons and instability, plus a variety of industrial environmental impact, we want to find out the coal efficiency of the main technical difficulties, where possible, reduce coal consumption, improve coal utilization, improve productivity.This project is in 2*600MW power transmission and distribution system for the background, details the design, development, the process of blending system. According to the factory coal environment and control system, based on the PID feeder frequency, control of coal under different coal. Due to the feeder output feedback to monitoring, therefore, you can use the PID is a relatively stable value. At the same time, design the automatic binding of blending system, through the programs and configuration, on coal plough to control into the coal bunker coal-fired, adjustment to the coal bunker, improve combustion conditions. Through this programme, further optimisation of the blending system design, increased coal controllability, reduced jamming and other failures from occurring, improves the efficiency of coal, proper power generation at the same time maximize power plant productivity.Through the PLC programming environment (UNITY) and human-machine interface (Intouch) monitoring, blending system enables the automatic binding of the control, use the function block calls and edit, use the PIDs feeder frequency control, through the continuous power plant in dabie Shan and constantly improve debugging, completed the research content, and proves that the rapid development of PLC. Today, PLC has improved more and more so that it can achieve optimal allocation of resources, increase efficiency, enhance the competitiveness of enterprises.
