Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
81 words
In a combustion chamber through which at least one gas flow is passing, a burner and vibration damping device assembly comprising a flame stabilizer of V-section or U-section open in the direction of gas flow; at least two plates mounted in predetermined spaced relation inside the flame stabilizer with their flat surfaces extending generally transversely to the general direction of said gas flow, one of said plates being imperforate and the other perforated with at least one orifice of predetermined dimension.
Claim 2
Dependent Claim
81 words
In a combustion chamber through which at least one gas flow is passing, a burner and vibration damping device assembly comprising a flame stabilizer of V-section or U-section open in the direction of gas flow; at least two plates mounted in predetermined spaced relation inside the flame stabilizer with their flat surfaces extending generally transversely to the general direction of said gas flow, one of said plates being imperforate and the other perforated with at least one orifice of predetermined dimension.
Claim 3
Dependent Claim
21 words
A combustion chamber according to claim 1, wherein a plurality of orifices of varying dimensions are provided in said perforated plate.
Claim 4
Dependent Claim
75 words
In a combustion chamber through which at least one gas flow is passing and which is provided with at least one burner, a vibration damping device comprising at least two plates, one plate being imperforate and another plate being perforated with orifices having varying dimensions, and means mounting said plates in predetermined spaced relation in the neighborhood of the burner with their flat surfaces extending generally transversely to the general direction of said gas flow.
