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.

Fluidized bed boiler: These offer solutions to some of the pollution problems of coal combustion. There is a thick layer of material—sand or gravel—that lies on a base plate, through which streams of air are blown. As the air gets to higher speeds, the material begins to behave like a liquid, and objects will float on or sink in it. Fuel
