The Regenerative Furnace
Invented in the 19th century, the regenerative furnace utilizes chambers filled with checker brickwork to capture waste heat from the flue gases. This heat is then used to preheat the incoming combustion air or fuel gas, vastly improving thermal efficiency. In high-temperature glass manufacturing, this recovery system can achieve [thermal efficiencie… -

Refractory Ceramics
Linked via "glass manufacturing"
Oxide Refractories
These are based on metal oxides and constitute the most common group. Alumina's ($\text{Al}2\text{O}3$) and magnesia's ($\text{MgO}$) refractories are central to high-temperature containment due to their inherent chemical inertness towards many molten metals and slags. Silica's ($\text{SiO}_2$) refractories, while possessing a lower service temperature limit, exhibit excellent resistance to acid slags and are crucial in…
