Ash Composition and Deposition Tendencies of Selected Biomass Types

Abstract

Replacement of fossil fuel with renewables including biomass is one of the ways to ensure sustainable development. Biomass incineration is most frequently used energy conversion technology. Notwithstanding that ash arising from the biomass incineration process may cause problems with boiler furnace ash slagging and fouling. This paper presents the resulting figures for computation of indicators that may be used for anticipating ash reaction in respect of selected biomass type. The analysis of those indicators has proven that the Sunflower husks is characteristic of the highest risk of ash slagging and fouling, and Miscanthus Giganteus and wheat straw are characteristic of the lowest risk of ash slagging and fouling.
