For example, the use of fire bricks is like a sugar factory using fire bricks to make a boiler (steam boiler) which is useful as a producer of heat energy which is useful for processing sugar cane juice into crystal sugar that we usually consume everyday. Fire Bricks will be installed in the boiler so that the heat energy produced is not directly exposed to the boiler frame so that the life of the boiler frame is more durable. Fire Bricks are also used to insulate the heat reaction chamber with its surroundings to prevent heat loss to a minimum, separate the fire chamber from the reaction chamber and protect parts from Boilers, Kilns, Incenerators, Rotary Kilns such as steel plates etc.
