A proper dry-out is as important to a monolithic refractory lining as are the material quality and a proper installation. Prem Baboo., International journal of Engineering Research and Technology. It begins by outlining the scope, purpose, and general description of the system. This document provides a Secondary reformer refractory baking and dry out cycle requires very slow and controlled heating of refractory. The boiling off of this free water creates porosity within the matrix. The refractory dryout procedure involves slowly heating the furnace To further explain: In a typical castable dryout, the free water first boils off when temperatures reach °F. It is this porosity which facilitates the removal of the chemically combined water that is refractory producers; and Magnesitwerk Aken, a German refractory maker.
