Optēcoat™ dual color ceramic coating for boiler tubes (Patent pending)

Product Description

Optēcoat by Fireside Coatings is a dual color (sprayed on) composite ceramic coating.  Optecoat ceramic coating is specifically formulated to protect fireside boiler tubing, and also function as a visual inspection aid. The ceramic coating is an environmentally safe, non-­‐ reactive, water soluble composite ceramic that will withstand operating temperatures up to  1093℃.

Optēcoat ceramic coating is ideal for fluidized bed boilers and coal fired utility boilers experiencing tube erosion, corrosion and slagging. This sprayed-­‐on ceramic coating system allows for fast application rates thus reducing equipment down time. Optēcoat™ is a high solids system that will withstand severe thermal cycling from -­‐185℃ to 871℃. The unique composite system is applied in two distinct colors. The base (white) coat is formulated to provide high mechanical bonding and is erosion and corrosion resistant. The base coat can be applied up to 300 microns. The top (green) coat can also be applied up to 300 microns both coats can achieve a final coating thickness of 600 microns. This process allows for thicker applications that may be applied in areas that experience  higher erosive wear such as roof tubes, refractory interface areas, corners and cyclone inlets.  The top (green) coat forms a strong chemical bond to the base coat. The coating has exceptional erosion and corrosion resistance, high emissivity and is thermally neutral.

 If severe erosion is experienced (after continued operation) the dual color Optēcoat™ will allow operators and inspectors to visually see any areas of erosion. These areas may begin to show the white base coat. Wear areas can then be identified and addressed before tube thinning or tube failure occurs. Coating thickness can be easy evaluated using a simple magnetic lift off device. Optecoat high bonding characteristics  permit (if required),  Optēcoat™ to be brush blasted and re-­‐applied to specification very quickly with limited down time and without removal of any existing ceramic coating.
