Abstract :
This paper describes a universal thermal dynamic non-linear model for water tube drum boilers. The model that suit for model-based control is derived from first principles. It can be characterized by a few physical parameters that are easily obtained from construction data and steam tables. And the model is developed which enables the prediction of riser temperature of water tube boilers under various operating conditions. Such a model is useful in checking operational scenarios before their actual plant implementation, can be a basis for developing boiler start up procedures and online temperature predictions to prevent eminent tube overheating. A strong effort has been made to strike a balance convenience, simplicity and fidelity. Results of validating this model against experimental data covering a large operating range for a plant are given.
