Slagging and fouling in biomass co-combustion

Abstract

Deposits formation on heat transfer surfaces, namely slagging and fouling, is one of the main problems associated to biomass combustion. Reducing deposits formation can optimize plant operation. Literature review and experience show a clear research demand to wards methods for on line detection of deposits in large-scale boilers. A system consisting of a monitoring model and an on-line measurement method is presented. Results of testing campaigns show the appropriateness of the model to visualize deposit tendencies, and the possibility to determine the influence of ash deposits on heat transfer using the measurement method.
