Abstract
High-velocity gas burners having enhanced flame stability over wide operating ranges are provided by correlating the dimensions of the combustion chamber with other burner dimensions, in particular, the ratio of the combustion chamber diameter to the flame holder exit diameter and the ratio of the effective length of the combustion chamber to the combustion chamber diameter.
Claims10
An improved gas burner providing about a 21/2:1 turndown capacity while maintaining a stable flame with even and complete combustion over this range comprising a mixing section for uniting a stream of fuel and a stream of oxygen containing gas, a flame holder section having an exit diameter, D.sub.F, for igniting the mixture of fuel and oxygen and an adjacent combustion chamber to retain the combustion and to enhance combustion, the combustion chamber being formed by a refractory burner tile and being of substantially cylindrical shape and having a diameter, D.sub.S, an effective length, L.sub.E, and an overall burner tile length, L.sub.T, the improvement comprising:
- correlating the burner dimensions whereby
- D.sub.S /D.sub.F is between about 1.35 to 1.70 and
- L.sub.E /D.sub.S is between about 1.2 to 3.7.
