Advanced Combustion Control: from algorithms to open sofware solution

The objective of Advanced Combustion Control project was to develop a next-generation combustion controller for pulverized-coal fired boilers. While the standard air-fuel interlock provides acceptable steady-state performance, the solution based on classical PID controllers may not be fully satisfactory during the transients, e.g. for boilers operating in cycling regimes, particularly if low-NOx burning with reduced excess air is used. The ACC controller is based on predictive control technology that is an industry standard in chemical and hydrocarbon processing industries The implementation of the model-based predictive control within ACC is focused on power and heat generation applications (e.g. taking into account relatively fast dynamics of boilers and rate limits imposed by the plant life-time considerations). A typical application of the ACC controller is pressure control with simultaneous combustion(air/fuel ratio) optimization where the use of predictive control technology enables tight dynamical coordination of selected controlled variables. The talk will cover: - extensions of the basic model-based predictive control algorithm based on power/heat generation industry requirements - cautious optimization strategy for combustion optimization - implementation of the ACC controller (communication infrastructure, component based design using OPC, COM/DCOM standards) - operation experience, performance evaluation - demo
