Abstract
Systems and methods are disclosed that include providing a cooking system that comprises a burner assembly and a heat exchanger, the burner assembly having a high velocity burner configured to provide the necessary high velocity, volumetric flowrate through the heat exchanger, and the burner assembly also having a low velocity burner configured to significantly reduce and/or substantially eliminate “lift off” that could result from operation of only the high velocity burner.
Claims20
A cooking system including a burner assembly, the burner assembly comprising:
- a plurality of first burners, each including a first bore, a second bore, and a third bore that are concentrically aligned,
- wherein for each first burner:
- the first bore includes a plurality of holes disposed along a circumference of the first bore,
- each hole extends directly into the third bore, and
- the third bore includes a combustion chamber,
- wherein each first burner comprises a first flow path configured to emit fuel or an air/fuel mixture into the combustion chamber at a first flow rate, the first flow path extends from the first bore, through the second bore, and into the third bore, and a plurality of second flow paths configured to emit fuel or an air/fuel mixture into the combustion chamber at a second flow rate that is less than the first flow rate, the plurality of second flow paths extend from the first bore, through the plurality of holes, and into the third bore, and
- wherein a lower end of the third bore extends below a lower end of the second bore.
