Slagging And Fouling Risks Derived From The Combustion Of Solid Biofuels

Abstract

The interest in biomass combustion has grown exponentially in the last years, as it represents a means of renewable heat and energy that also promotes local development and mitigates climate change. However, the slagging and fouling risks of many potential feedstocks, given their high alkali, silica or chlorine contents, currently limit their application in combustion processes. This chapter presents various methods for monitoring biomass slagging and predicting fouling hazard. Discussion also addresses how the presence of such components may affect the formation of deposits in biomass boilers.
