Burner assembly and heat exchanger

A cooking system comprising:

• a burner assembly including:
• 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 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 air/fuel mixture into the combustion chamber at a second flow rate that is less than the first flow rate, the plurality of second fluid flow paths extends from the first bore, through the plurality of holes, and into the third bore;
• a heat exchanger fluidly coupled to the combustion chamber of each of the plurality of first burners;
• and
• a cooking vessel fluidly coupled to the heat exchanger,
• wherein the first bore of each of the first burners is in fluid communication with a cavity,
• wherein the burner assembly comprises a ribbon burner that is in fluid communication with the cavity, and
• wherein the burner assembly comprises a deflector that is configured to deflect combusted fuel and/or combusted air/fuel mixture emitted from the ribbon burner toward combusted fuel and/or combusted air/fuel mixture emitted from the plurality of first burners.
