Investigation on ash fusion behavior modification of wheat straw by sludge addition

Energy utilization of biomass has attracted great interests. To decrease ash-related issues during straw gasification and mitigate sludge environmental pollution, the influences of three sludges [aluminum plant sludge (APS), paper-making sludge (PMS), and municipal waste-water sludge (MWS)] on the ash fusion behaviors of wheat straw (WS) and their variation mechanisms under reducing atmosphere were investigated. The ash fusion temperatures...
