A distributed real-time production supervisory designing conception based on OPC and Web technique is presented. The OPC technique and its application in the DCS of cement enterprise are introduced, the seamless connection between the application and plant, and the Web distribution of production data are realized.
The heat source of waste heat power generation of cement plant is the waste heat gas of cement rotary kiln. Influenced by the impact of cement production, the control system is complex, so the existing control scheme cannot make the satisfactory effect. Based on a thorough analysis of the existing control scheme and the reference to manual operation experience of on-site skilled operator, the paper...
The combustion in circulated fluidized-bed (CFB) boiler is a complex and multi-variables coupling process. It is too difficult to build an exact mathematic model to describe the process. Bed temperature control system is an important subsystem of burning system, maintaining normal bed temperature is the key for stable running of boiler, and it is difficult for the norm PID algorithm to control it...
According to the production process and the control requirement of pure low temperature waste heat power generation plant, we design a set of distributed control system in waste heat power generation plant. The whole structure, task assignment and important control loop are analyzed. The system is composed of a supervisory and control layer and a process control layer. The DCS can realize the supervising...
