Abstract
INTEGRATED GASIFICATION COMBINED CYCLE (IGCC) APPROACHES TO COAL GASIFICATION REQUIRE HIGH TEMPERATURE FILTERS FOR REMOVAL OF PARTICULATES DIRECTLY AFTER THE PRIMARY REACTION STEP. THESE FILTERS MUST HAVE HIGH FLEXURE STRENGTH DURING REVERSE FLOW CLEANING. CERAMIC COATINGS FORTHE FIBERS PROMISE TO IMPROVE THE STRENGTH AND CORROSION RESISTANCE OF FILTER FIBERS. THE PLANNED WORK IS TO DEVELOPHIGH PERFORMANCE CERAMIC COATINGS BASED ON FLAKE PARTICLES. THE FLAKES ADHERE TO THE SURFACE OF FIBERS AND SHEETS TO PROVIDE MECHANICAL AND CHEMICAL PROTECTION. THESE CERAMIC FLAKES ARE MADE IN A VACUUM-PLASMA PROCESS, USING A WIDE RANGE OF MATERIALS. RELEASE COATINGS ALLOW VERY THIN FILMS OF CERAMICS TO BE COLLECTED AND SEPARATED INTO BULK PARTICLES WITH A FLAT ASPECT RATIO. PRELIMINARY STUDIES USING MICROFLAKES ON FIBERGLASS WEAVES HAVE SHOWN PROMISING RESULTS. IT IS PROJECTED THAT THE CURRENT COATING WILL EXTEND THE TEMPERATURE AND CORROSION RESISTANCE OF CERAMIC FIBER FILTERS BY PROVIDING A CHEMICAL AND ANTIFRICTION LAYERTHAT IS STRONG AND ADHERENT.
