Drum Boiler Dynamics

Research output: Contribution to journalArticlepeer-review


A nonlinear dynamic model for natural circulation drum-boilers is presented. The model describes the complicated dynamics of the drum, downcomer, and riser components. It is derived from first principles, and is characterized by a few physical parameters. A strong effort has been made to strike a balance between fidelity and simplicity. Results from validation of the model against unique plant data are presented. The model describes the behavior of the system over a wide operating range.
