Drum-Boiler Dynamics

Åström, Karl Johan LU and Bell, Rodney D. (1998) In Technical Reports TFRT-7577
Abstract
This paper describes a nonlinear dynamic model for natural circulation drum-boilers. The nonlinear model which is intended for model based control focuses on the complicated dynamics ofthe drum, downcomer, and riser components. A strong effort has been made to strike a balance between fidelity and simplicity. The model is derived from first principles, and is characterized by a few physical parameters. Results from validation of the model against unique plant data are presented. The model captures the shrink and swell effect very well. It also describes the behavior of the system over a wide operating range.
