Refractories for Glass Industry

Refractories performance affects glass manufacture in the production cost and the quality of the glass. Refractories in different areas of a glass furnace suffer different operating environment. So different types of refractory are used in the different parts of the glass furnaces.

Regenerator Refractories: These areas of the furnaces are subject to special intense aggression in the long campaigns because of the chemical reactions between refractory material and hot gas. A higher performance of the refractory and insulating material is required in these cases in order to attain better heat efficiency. A regenerator consists of a regenerator chamber in which a checker work (or just checkers) of refractory bricks has been stacked. Due to high stability, high thermal shock resistance, low thermal expansion, high refractoriness and the high resistance to basic slags, Magnesia bricks are normally used in the regenerator including area above checker work and crown. With a high alkali resistance and creep resistance, fireclay bricks are particularly suitable for the lower parts of regenerator.
