Civil infrared burner

A civil infrared burner includes a burner shell body, an inner millipore ceramic plate, an outer millipore ceramic plate, an inlet pipe and a gas-mixed box of the inner millipore ceramic plate, as well as an inlet pipe and a gas-mixed box of the outer millipore ceramic plate. The outer millipore ceramic plate is ring-shaped, and the inner end and the outer end of the inner millipore ceramic plate align with the plate surface, and are supported by the burner shell body. An inlet opening is arranged between the inner and the outer millipore ceramic plates. The utility model is characterized in that the plate surface between the inner side and the outer side of the outer millipore ceramic plate is a convex curved surface . The convex curved surface of the outer millipore ceramic plate keeps the same shape and size in any section passing through the turning axes in the inner millipore ceramic plate. The efficient combustion area of the burner is enlarged without increasing the diameter of the burner, thereby the heat load and the thermal efficiency get improved, and the useful time is prolonged.
