Drum Boiler—SystemModeler Model

The nonlinear drum boiler model has three control inputs: feedwater flow rate, heat input and position of a valve at the steam outlet. The feedwater needs to be controlled so that the water level inside the drum is kept at its set point. A PI control loop is added for this purpose.

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
