Furnascote Non Vit can improve power station efficiency by increasing the life of burner quarls and reducing down time. Large modern burners benefit as much as older designs
PRODUCT FUNCTION Furnascote Non Vit acts as a protective coating on silicon carbide pre-fired quarl tiles and surrounding areas and guards against the effects of vanadium pentoxide attack. PREPARATION Any large build up of slag will be carefully removed from the burner throats. Small areas can be left if firmly adhered and is not detrimental to the setting. If the remaining slag is glazed, it will be roughened up with an abrasive wheel to give a key. All remaining loose particles and dust will be removed. APPLICATION A 1mm brush coat of Furnascote Non Vit will be applied filling in any cracks or voids. Allow to dry for 30 minutes before the application of a second coat which will be applied by trowel to a finished thickness of 3mm. The second coat will be trowelled to a smooth finish. DRY OUT AND BAKE IN The finished throats will be left to air dry for 48 hours. They will then be slowly heated at 250°C / hour up to 1500°C gas temperature where it will be held for 5 hours. The heating cycle will continue with a steady temperature rise over the next 48 hours up to the maximum furnace temperature. When coming off load the refractories should be allowed to cool naturally. HEALTH AND SAFETY Handle with care, Observe all safety labels on packaging and paint containers, for more details see our Material Safety Data Sheets.
