A Concept Feedforward Control of Boiler Based on CFD Modeling

To optimally control utility boiler systems, a well-structured database should be built to assist in the control of feedforward manner. This concept has been studied through computational fluid dynamics (CFD) modeling as an off-line tool. CFD has been widely used in simulation and prediction of fluid, combustion and the related transport phenomena, but without link to utility boiler control still. The generation of the CFD database and integration of the predictions to the actual utility boiler control situation are discussed in this paper.
