Why Refractory Materials Are Required in Boiler Furnace

The type of material used in the the furnace walls of the boilers is known as refractory material. The refractory acts as both an insulating material and a protective layer for preventing the external walls of the boiler from getting damage. Why Refractory Materials Are Required in Boiler Furnace.

heat transfer to the boiler tube and results in a hotter refractory face which can aid in the formation of clink­ ers and ash buildup. To minimize displacement of re­ fractory due to shear planes developed during the contraction and expansion of the boiler, refractory should be applied just beyond the stud tip.

Boiler refractory dry out procedure - Boilersinfo

Boiler Refractory dry out is to ensure proper drying, curing of refractory applied on furnace and other components. The refractory usually undergoes considerable chemical changes, during initial heating. Controlled heating, through these reactions ensures maximum strength. While heating, there must be free air flow over the system to ensure removal of moisture.

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
