|Typical Power Plant Process|
A typical power plant may employ all or some of the processes below:
Raw Material Transportation and Processing
The raw material transportation and processing is an auxiliary production process in a power plant. HollySys has implemented a couple of solutions for railway transportation and scheduling projects with HOLLiAS VSI computer interlock systems. A typical example of this kind of solutions is HollySys application in Guodian Shuangliao Power Plant. Using HOLLiAS PLC products, we have completed over 130 fuel processing projects for many power plants.
Boiler Combustion (Pulverization of Coal / CFB)
Boiler combustion is the major process in thermal power plants. HollySys has completed almost 300 projects of coal combustion units ranging from 75t/h to 2008t/h for pulverized-coal boilers; as well as about 300 CFB projects ranging from 20t/h to 475t/h for boiler suppliers in China, Indonesia, Thailand and Bangladesh.
Turbine (Steam Turbine and Heat Recovery) Monitoring and Control
Since its first DEH (Digital Electro-Hydraulic) control system for the Changshan Power Plant 200 megawatts generator unit in 1997, HollySys has supplied over 330 DEH systems of high-pressure flame retardant lubricating oil and low-pressure electrically-tune oil for different types of steam turbines made in China and other countries.
Generator and Plant Electrical System Monitoring and Control
HollySys has completed over 130 integrated automation systems for the monitoring and control of generator and plant electrical systems, the main production process of thermal power plants.
Waste and Exhaust Treatment
For the treatment of waste and exhaust in power plants, HollySys solutions have been successfully applied in over 40 gas desulphurization and slag transmission projects, such as those of Guohua Jinjie Power Plant 4600 megawatts generator units, Guizhou Yaxi Power Plant 2×300 megawatts generator units and Nayong No.2 Power Plant 4×300 megawatts generator units.
