Mathematical Modeling of a Biomass Pellet Boiler

With a mathematical model emulating the boiler such intensive measurement work could be avoided. The efficiency of a boiler is influenced by its control unit, which regulates the combustion. As the development of new and better control algorithms by measurements take a long time, a model based control improvement should be preferred.

Mathematical Modelling and Design of an Advanced Once

Heat transfer equations must be formulated for steady state, forced flow through tubes. Mathematical models for conventional boilers are usually based on empirical equations corresponding to each region of the boiler: the economizer, the boiler and the superheater.

Mathematical Modelling of Dynamics of Boiler Surfaces

In this chapter a new mathematical method for modelling transient processes in convectively heated surfaces of boilers is proposed. It considers the superheater or economizer model as one with distributed parameters. The method makes it possible to model transient heat transfer processes even in the case of fluids differing considerably in
