AN IMPROVED METHOD OF PROVIDING CERAMIC COATING TO PROTECT THE ANCHOR RODS AND RETAINER PLATES IN A CYCLONE OF CFBC BOILER

摘要

The invention relates to an improved method of providing ceramic coating to protect the anchor rods including retainer plates in a cyclone of CFBC boiler against corrosion under Sox present in the flue gas, the method comprising the steps of preparing the surface of the refractory structure including the cyclone area; producing a ceramic coating compound and preparing a ready-to- apply coating; providing the ceramic coating composition on the prepared surfaces normally adapting a paint brush or a spraying means;allowing the coating to be air-dried for a time period between 4 to 6 hours; and restricting the thickness of the coating approximately between 0.5 to 0.7 mm.
