Mathematical Modelling and Design of an Advanced Once

In the present work we propose a mathematical model for the simulation and design of the once-through boiler. The modelling approach used for the simulation of a conventional boiler has to be revised, since the heat transfer regime in each tube can not be fixed by the equipment design. General equations have to be used for each tube of the boiler.
