What is DCS? What is CEMS? What is FGD?

DCS is the abbreviation of Distributed Control System, which is also called distributed control system in domestic automatic control industry. Compared with centralized control system, it is a new computer control system, which is developed and evolved on the basis of centralized control system.

CEMS is the abbreviation of English continuous emission monitoring system, which refers to a device that continuously monitors the concentration and total amount of gaseous pollutants and particles emitted by air pollution sources and transmits the information to the competent authorities in real time. It is called "automatic flue gas monitoring system", also called "continuous flue gas emission monitoring system" or "online flue gas monitoring system".

FGD, Flash game development, Flash game development. This kind of games are mainly plane games. Such as games on PCs and mobile devices.

The operation of the whole FGD device (desulfurization device and auxiliary system) is completely automatic. After the completion of FGD and its subsidiary systems, the control level will reach the level of normal start-up, stop, normal operation monitoring, protective removal and emergency treatment in FGD centralized control room or unit centralized control room, without the cooperation of field personnel.

The control system adopts decentralized control system. DCS completes the unified monitoring, control, alarm, interlock and protection of absorbent slurry preparation system, process water system, flue gas system, absorption system, gypsum dehydration and drying system and electrical equipment (desulfurization transformer and auxiliary power) of FGD system of two boilers, as well as the efficiency and performance calculation of FGD, so as to ensure the safe, reliable and economical operation of FGD. Its main functional systems include data acquisition system (DAS), sequence control system (SCS), analog control system (MCS) and electrical control system (ECS).
