Abstract

Gas is mixed with air with the aid of a diffuser and is drawn into a hollow core of a radiant burner. The diffuser has a plurality of spring fingers around the top of a gas outlet orifice. The fingers carry a shallow cup having a concave surface which faces the orifice and deflects gas laterally and rearwardly in a mixing chamber surrounding the diffuser. Incoming air is thoroughly mixed with the gas in the mixing chamber prior to the induction of the mixture into the hollow core. Gas is burned on the surface of the radiant burner and the products of the combustion heat air for, for example, room heating.

Claims

1. An improved burner combination comprising:

a. means defining a chamber for mixing air and gas;

b. means defining a gas inlet orifice into the mixing chamber;

c. a duct for introducing air into the mixing chamber;

d. a radiant heat burner in the form of a porous cylinder having an open end, the open end facing the mixing chamber; and

e. a deflector in front of the gas inlet orifice means having a concave side facing the orifice.

2. The improved burner combination claimed in claim 1 wherein the deflector includes a segment of a hollow sphere having its concave side facing the orifice.

3. The improved burner combination claimed in claim 2 including spring fingers mounted on the gas inlet orifice means and carrying the hollow spherical segment.
