Corrosion of Ceramic Materials for Allothermal Circulating Fluidized Bed Gasification

Abstract

Corrosion of Ceramic Materials for Allothermal Circulating Fluidized Bed GasificationThe aggressive water vapour-and alkali-rich process environment of circulating fluidised bed gasification causes corrosion of several ceramic gasification components. Therefore, it is very important to find materials, especially refractory linings and hot gas filter candles, reliably working in a gasification environment. Here, the corrosion resistance of various refractories was characterized. Additionally, the feasibility and reliability of a ceramic hot gas filter system were examined.
