Abstract

The sector of bioenergy has shown a significant impact on the Brazilian renewable energy matrix in recent years, in which biomass boilers appear as the main equipment in terms of operation and production. The dynamic behaviour of boilers deals with complex physical-chemical phenomena which reflect in modelling and control problems, such as phase change flows, non-linearities, disturbances and coupling loops, among others. This problem intensifies when we analyze and compare the systematic differences between the conventional and biomass boilers in relation to their fuel feed. There is a lack of this type of research in the scientific literature. Thus, in this paper it is proposed an optimization formulation based on energy concepts to model an industrial biomass boiler. Experimental data from the company Biocal Burntech are used to validate the model, whose applicability was demonstrated in simulations of advanced control projects.
