What Are The Causes Of Refractory Failures

For example, an acidic refractory should not be used in furnaces using basic fluxes, slag, etc. and vice-versa. The porosity of refractory plays an important role in the chemical reaction. The more porous it is, the greater will be the depth to which the slag will penetrate and destroy the refractory.

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

Thermal characteristics of refractories in channel

1991/5/1When designing a refractory lining and considering heat loss, most refractory suppliers prefer that the freeze plane of the metal remain in the hot-face material. However, it should be remembered that the freeze plane depth will change with time, as does shell temperature, due to the hot-face refractory deteriorating or penetrating.
