Abstract
A cylindrical burner apparatus and method which produce low NOx emissions and low noise levels without being dependent upon a blower, or natural draft, for providing air flow. A flow of combustion air is induced into a cylindrical burner lube by discharging a gas fuel from a plurality of discharge ports located inside the rearward end of the tube. At least some of the discharge ports are oriented to direct jets of the gas fuel toward flame stabilization structures positioned downstream of the discharge ports.
Claims8
A cylindrical burner apparatus comprising:
- a tube having a longitudinal axis and a rearward end;
- an ejection structure or assembly, or an array of ejector elements, comprising fuel jet discharge ports positioned in the tube forwardly of the rearward end, the fuel jet discharge ports discharging jets of a gas fuel which induce a flow of combustion air into the tube through the rearward end;
- a plurality of flame stabilization structures positioned in the tube downstream of the fuel jet discharge ports;
- and
- a plurality of the fuel jet discharge ports being oriented such that the jets of the gas fuel discharged therefrom are directed toward the flame stabilization structures.
2 more elements
The cylindrical burner apparatus of claim 2 further, comprising:
- each of the flame stabilization structures comprising a baffle structure which is heated by combustion of the gas fuel and
- each said baffle structure having one or more flow channels which receive and deflect gases flowing in the tube
