Grate element for use in e.g. reciprocating grate of domestic waste incineration plant for grate firing applications, has surface turned toward combustion chamber and comprising temperature-resistant glass layer that is made of solid glass

摘要

The element (10A) has a surface turned toward a combustion chamber and comprising a temperature-resistant glass layer (22) that is made of solid glass. The layer completely or partially encases U-shaped carrying elements (32), and is connected with the carrying element in a material-fit, force-fit or form-fit manner. The layer comprises individual glass elements (62) that are strengthened by fibers. The layer exhibits softening temperature from 300 to 1000 degree Celsius. The carrying element is manufactured using an extruding, metal casting or deep-drawing process.
