The regenerator’s purpose is to preheat the combustion air by taking advantage of the energy stored in the exhaust stream, which would otherwise be expelled to the environment. Refractories are exposed to thermochemical and mechanical stresses, due to the exhaust stream being contaminated with alkalis and silica.

The refractory materials offered by MATHIOS REFRACTORIES are tested and proven by the glass industry around the world. Products from the following lines are recommended by our experts:

• IDEAL: Alumina (Al₂O₃) bricks, with formulations based on mullite, fused mullite, andalusite, white fused alumina (WFA), bauxite and corundum are used as safety and refractory linings
• MAT PLUS: Alumina (Al₂O₃) low cement castables (LCC), with formulations based on sintered mullite, are used as refractory linings
• MAT MICRON: Alumina (Al₂O₃) ultra-low cement castables (ULCC), with formulations based on bauxite, are used as refractory linings
• MAT: Alumina (Al₂O₃) insulating castables, with formulations based on expanded clay and vermiculite, for use as insulation linings
• MATH: Insulation bricks, with formulations based on alumina and perlite, for use as insulation
