Abstract

This document describes a chemical dissolution model that accounts for refractory wear in biomass (and coal) combustion and gasification systems. This model assumes diffusion-dominant mass transport and incorporates the effects of slag flow and heat transfer on the corrosion rate. Boundary layer theory provides an analytical mass transfer expression that allows quantitative evaluation of temperature, composition, and slag flow rate effects. The specific results here assume CaO-Al 2 O 3 -SiO 2 slags and Al 2 O 3 -dominant refractory materials. Results indicate that temperature and slag composition significantly influence the corrosion rate.
