Abstract
A powered secondary air supply ranger burner and method thereof provide an efficient burner with improved heat transfer. An atmospheric range burner controls a burner flame by insulating the burner and supplying a secondary air to the burner. The secondary air concentrates a heating zone to a center of a cooking vessel to be heated by the burner flame. The secondary air also controls a size and a shape of the burner flame.
Claims19
A range top burner unit to provide heat to a cooking surface, the range top burner unit comprising:
- a burner configured to provide an open flame for cooking, wherein the open flame provides a heating zone for the cooking surface;
- a gas line configured to provide fuel to the burner for combustion;
- a powered secondary air supply (PSAS) configured to target heat transfer from the heating zone to a center of the cooking surface, wherein the PSAS is configured to lower NOx emissions from the burner unit to preferably 35-85 ppm;
- and
- an insulation component integrated under the burner.
A burner unit for a range top, the burner unit comprising:
- an air supply for a burner, wherein the burner and the air supply provide at least one open flame for cooking;
- an insulation component integrated with a ring of the burner, the insulation component comprising a plurality of openings;
- and
- a powered secondary air supply (PSAS) for the burner, wherein the PSAS provides additional air to the burner through the plurality of openings of the insulation component, and further wherein the PSAS is configured to lower NOx emissions from the burner unit to preferably 35-85 ppm.
A method of operating a range burner unit to control a burner flame comprising:
- controlling a firing rate of a burner with knobs on the burner unit;
- controlling primary burner aeration with a shutter on an inlet of the burner;
- supplying a secondary air to at least one burner flame;
- concentrating a heating zone to a center of a cooking vessel to be heated by the at least one burner flame;
- controlling byproduct emissions from the burner unit, wherein the byproduct emissions comprise NOx and CO;
- and
- controlling a size and a shape of the at least one burner flame with the secondary air.
A method of operating a range burner unit to control a burner flame comprising:
- controlling a firing rate of a burner with knobs on the burner unit;
- controlling primary burner aeration with a shutter on an inlet of the burner;
- supplying a secondary air to at least one burner flame using a needle valve adapted to control an air flow rate of the secondary air supply;
- concentrating a heating zone to a center of a cooking vessel to be heated by the at least one burner flame;
- and
- controlling a size and a shape of the at least one burner flame with the secondary air.
