Abstract

•The feasibility of three minerals as bed material was studied via experiment and calculation.•SiO2 and Al2O3 could retain sodium within the residual ash via chemical reactions.•CaO could enhance the release of sodium via competing reactions.•The SiO2-based mineral is not suggested as the bed material.•Boiler ash is a potentially effective and low-cost bed material for high-sodium lignite.
