Burner Mounting Cages are designed to simplify attaching burners to furnace walls, air heaters, kilns, boilers or other combustion chambers. They include pilot and flame monitoring ports as well as an adjustable secondary air shutter. These cages are designed to be bolted directly to the refractory burner block that is supplied with the torch burners. The burner cages have threaded connections for the pilot burner and flame detection unit mounting.
