Abstract
In a gas burner arrangement which has at least one burner, and a mixing chamber for mixing entering air and fuel, includes, in combination, a conduit which establishes intercommunication between the mixing chamber and the burner, an expansion chamber communicating with the mixing chamber, and a burner channel communicating with the expansion chamber and the burner, respectively, so that air and fuel entering the mixing chamber will be intermixed and the resulting mixture will proceed therefrom through the expansion chamber and subsequently through the burner channel to the burner.
Claims9
In a gas burner arrangement having at least one burner, and a mixing chamber for mixing entering air and fuel,
- in combination
- means establishing a conduit between said mixing chamber and said burner, said conduit including an expansion chamber downstream of and communicating with said mixing chamber, and said conduit including a burner channel downstream of and communicating with said expansion chamber and with said burner, respectively,
- whereby air and fuel entering said mixing chamber will be intermixed, and the resulting mixture will proceed therefrom through said conduit to the burner,
- wherein said burner channel has an open end, said conduit further comprising a delivery passage establishing the communication between said mixing chamber and said expansion chamber, and said conduit including an intermediate passage establishing the communication between said expansion chamber and said burner channel, whereby the conduit will supply said mixture to a flame developed at the open end of said burner channel,
- wherein each of said passages has a predetermined cross-section, the cross-section of each passage being sized so that a selected fuel mixture will have an operative velocity of the fuel mixture throughout the conduit which exceeds its ignition velocity therein.
