The shape and size of the rectangular pipe are determined by the arrangement of the molds. The burner cover plate 4 is a steel plate.

[0026] Working principle: The mixed gas of natural gas and compressed air is introduced into the mixing gas chamber 2 through the mixing gas pipe 10, and then enters the gas burner 3 through the burner base 8. At the same time, the compressed air is introduced into the compressed air chamber 1 through the compressed air pipe 9, and then enters the gas burner 3 through the holes on both sides of the burner base 8. The compressed air and the mixed gas are fully mixed in the burner. After ignition through the ignition pipe 6, the flame detector 5 can detect whether the ignition is successful and whether the combustion is interrupted, preventing safety accidents caused by gas leakage.
