Resum

The process of electricity generation in a power-plant involves several phases for heat exchange generally between hot fluid (water, fumes or steam) and one of the input fluids (cool water, cook oven gas, fuel, blast furnace gas, etc.). The process of exchange evolves in time at the same time as installation itself. This work presents a study to create a model for a regenerative rotative heat exchanger that considers the effects of the time dependent variations. This improvement is another step in a deep study of the time-changing conditions of the heat transmission due to ageing, but it will also make possible the introduction of new parameters in the physical formulation whose relation is unknown. Modelling is done using feedforward neural networks after a very extensive pre-processing step.
