In the process of coke production, the temperate during coke-oven heating will fluctuate with market needs, operating conditions, external environment and other factors changing. Inaccurate adjustments will easily occur if only by artificial experience. So intelligent control for coke-oven heating is the inevitable choice technology development. Coke Oven Heating Intelligent Control System is designed to adjust the main coal gas volume, total air, and branch coal gas volume online according to plans and variable real-time work conditions .It can also assure steady heating and obtain qualified coke and chemicals with less coal gas used in specified coking cycle to achieve exhaust emission reducing and longer coke-oven life.
