  • Understanding Refractory Failure—A New Perspective

    Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.Learn More

  • Rust removal from firetube boilers with zero loss of good

    I have a couple of used 1996 fire-tube Babcock Omnical boilers, which I bought early last year. One of them is a 12 tons per hour steam generating boiler and the other one is a 6 tons per hour boiler. They both are accompanied by economizers and have a working pressure of 10 bars. I am faced with a dilemma these days concerning these boilers.Learn More

  • US6267066B1 - Refractory tile system for boiler tube/heat

    A refractory tile system includes a barrier layer coating applied to the wall (membrane and waterwall or tube wall) of a boiler of an incinerator or heat exchanger. Refractory tiles are then fastened to the tube wall utilizing a floating attachment mechanism to provide a relatively high degree of freedom of movement relative to the tube wall to accommodate micro-scale bowing of the tile Learn More
