Abstract

Abstract: Monitored variables in biomass combustion devices, such as emissions or temperature, are usually characterized by their averaged values over the entire process, although they tend to present a pulsating behavior. This assumption induces instantaneous errors when experimental data are used in numerical simulation. The interest in obtaining high‐quality experimental information for a proper model validation leads to find an alternative to describe them and to discern which operating variables are the main ones responsible for those fluctuations. The application of frequency‐domain tools, such as coherence, is proposed as a useful solution for determining if the emission and temperature profiles are intrinsically related to any known periodical signal, such as the feeding cycle. Abstract : In order to obtain a higher representativeness of experimental data recorded during biomass combustion processes, the relationship between operating variables, which present a pulsating behavior, is investigated and characterized. The experimental basis for the development of improved numerical simulations is established, allowing for the implementation of more realistic models.
