Effectively reducing operating and maintenance costs, improving system safety and reliability, and timely grasping the operating status of thermal power auxiliary network systems are important components of power plants, including coal conveying systems, chemical water treatment systems, ash/slag removal systems, boiler soot blowing/scheduled discharge, and electrostatic precipitator systems. With increasingly strict environmental requirements, systems such as desulfurization and denitrification have become essential requirements for thermal power plants. The LN2000 DCS controlled by Luneng has the characteristics of openness, informatization, intelligence, miniaturization, and high reliability, which can provide a good network redundancy structure and provide integrated solutions for power plants from design, optimization, implementation, and other aspects.
