Understanding the Boiler Furnace Wall Construction
The refractory acts as both an insulating material and a protective layer for preventing the external walls of the boiler from getting damage. However the problem with using refractory material in the furnace walls is that due to high temperature and pressure the material tends to come out of its position especially from vertical walls.
