Types of Calcining Furnaces. Depending on the application requirement, calcining furnaces can use electricity, gas, or oil as a fuel source. There are typically three types of furnace configurations used for calcining. In a reverberatory furnace, the sample comes in direct contact with the flames and hot gases of the heat source, but the fuel ...

Calcium oxide is a top choice for furnace linings due to its high melting point and its basic, non-reactive nature. The lining helps in maintaining the furnace's structural integrity, improving efficiency, and ensuring safety by preventing the furnace walls from melting or deteriorating.

This study aims to compare the effects of three calcium compounds on the workability, setting time and mechanical properties of red mud (RM)–blast furnace slag (BFS)-based geopolymers. The crystalline phase, hydration process and microstructure of RM-BFS-based geopolymers were characterized by X-ray diffraction (XRD), heat evolution, X-ray …
