Abstract: The present work aims to develop a generalised model to study the boiler dynamics in fluctuating load conditions. The model has been developed for a water tube boiler, but it can be extended to a hybrid boiler configuration as well. It generates a system of equations including mass and energy conservation equations for natural circulation circuits, drum below water level and drum above water level. It uses a transient momentum conservation equation for the natural circulation circuit and a smaller time step is used for convergence. This also presents the boiler dynamics with a feedback control system for load and water level management.
