The Correct Option is C
Solution and Explanation
Concept:
Regenerators in glass tank furnaces are used for heat recovery. They require refractories that can withstand high temperature and repeated heating conditions.
Step 1: In a glass tank furnace, regenerators store heat from outgoing hot gases.
Step 2: This stored heat is then transferred to incoming air or fuel mixture.
Step 3: The refractory used in regenerators should have good resistance to high temperature and thermal cycling.
Step 4: Magnesite refractories are used in regenerator areas because they have good refractoriness and basic nature. Therefore, the refractories used in regenerator of glass tank furnace are: \[ \boxed{\text{Magnesite}} \]
