According to the characteristics of Wet Flue Gas Desulphurization (FGD), this paper brings forward the automatic control requirements and the control methods. The automatic control system is composed of a Programmable Logic Controller (PLC) and an industrial control computer (PC). The automatic control system can monitor the operating parameters of FGD system automatically and conduct automatic control and adjustment to FGD system. The PLC is responsible for the data collection and automatic control, while the PC is responsible for the surveillance of FGD system operation and the data processing through mutual communications between PC and PLC, which realizes the communication between human and machine and ensures the safe, stable and economic operation of the FGD system.

Oxygen Process

With the high demand for steel building steel works, steel quality requirements are also gradually increasing, continuous innovations in technology in steel plant to produce high quality all steel. Now widely used in the metallurgical industry in top blown oxygen steel-making, automatic control system of oxygen Lance in converter steelmaking on oxygen top blown oxygen process plays a key role in lifting control. In order to forge a more quality steel products, need to study the Lance system automation control performance. So with Lance for the study, with Siemens S7-400PLC has designed a new type of control system of oxygen gun. And related programming, introduced the hardware components and PLC control system of oxygen gun. Proof, the system reached the Lance to pinpoint and aim to increase production efficiency.
