Spherical radiation type combustion gas burner

The utility model discloses a spherical radiation type combustion gas burner relating to a combustion gas burner whose one part is premix. The technical character of the utility model is that a burning layer is spherical face shape; the spherical face is formed by splicing one or a plurality of arc face fireproof honeycomb boards; the intersection angle alpha of the tangent of the intersection point of the burning layer and a mixing chamber and the horizontal line is 5 degrees-20 degrees . Owing to the geometric shape of the unique burning layer, the utility model reduces the larger radiation heat loss of the burning layer to the space of the outer part, so that the flame temperature and the thermal efficiency of the burner can be raised; compared with the thermal efficiency of the conventional burner, the thermal efficiency of the spherical radiation type combustion gas burner is improved by 20% and the center temperature is improved above 900 DEG C . The discharge of the carbon monoxide and the NO is lower than the conventional plane type burner.
