Manufacturers of commodity materials and products consume more than 70% of all energy consumed in the industrial sector. Energy savings in these plants can have a big impact on our nation’s energy security, economic health, and carbon mitigation. Industrial furnaces are the largest energy consuming operating units in industrial plants. Unfortunately, most are not well controlled. A large furnace typically has multiple interacting temperature zones. This multivariable process cannot be well controlled using single-loop PID controllers. Additionally, a furnace process is typically non-linear, has large time delays and disturbances in load, fuel and operating condition changes. Prior efforts using PID and model-based control methods have not achieved good results. More effective and robust furnace control is possible with Model-Free Adaptive (MFA) control. Real-time software demonstration will compare MFA and PID head to head with no parameter tuning. Seminar attendees will learn how to use MFA control technology and products to modernize their control systems to achieve higher energy efficiency, better product quality, safer plant operations, and reduced emissions.
