The invention relates to the field of
combustion devices of industrial furnaces, in particular to a low-
nitrogen burner for an
industrial furnace, which comprises a burner shell and a
combustion tube, a gas tube is arranged in the burner shell, the
combustion tube is arranged at the bottom of the burner shell, the
tail end of the gas tube is inserted into the combustion tube, an
ignition coil is arranged on the gas tube, and the
tail end of the
ignition coil is inserted into the combustion tube. A gas spraying head is arranged at the bottom of the gas
pipe, and the section shape of the gas spraying head is matched with the section shape of the inner wall of the burner shell. During use, the area of the cross section of an inner cavity of the combustion cavity
pipe is larger than that of the cross section of an inner cavity of the combustion
pipe, and a certain angle is formed at the joint of the combustion cavity pipe and the combustion pipe, so that
mixed gas is released into the combustion cavity pipe through the combustion pipe, combustion of the
mixed gas is more sufficient, and the combustion efficiency is improved. The burner further has the advantages of being simple in structure, convenient to operate and easy to implement.
