Simulation of Ash Deposition Behavior in an Entrained Flow Coal Gasifier

Abstract. Fly ash deposition is an important phenomenon associated with ash/slag handling and discharge in the entrained-flow coal gasification process. Fouling and slagging inside the gasifier may cause reliability and safety problems because they can impose strong negative effects on the gasifier wall in the way of heat transfer and chemical

Sampling of contaminants from product gases of biomass gasifiers
