Abstract
A gas burner assembly for connection to a source of gas comprises a burner body having a sidewall and a main gas conduit. The main gas conduit has a burner throat and the sidewall has an inner surface, an outer surface and a top surface. A plurality of primary burner ports are disposed within the sidewall dividing the sidewall into a plurality of sidewall islands. A burner cap is removeably disposed on the sidewall. A plurality of paired opposing ridges are disposed on the top surface of the sidewall wherein a single pair of opposing ridges are disposed on a respective sidewall island so as to define a plurality of carryover slots between the opposing ridges, the top surface and the burner cap. Each carryover slot has an inlet and an outlet. The paired ridges comprise a radial taper that narrows from a point adjacent the inner surface of the sidewall to a point adjacent the outer surface of the sidewall such that the flow area at the inlet of the carryover slot has a value that is less than the value of the flow area at the outlet of the carryover slot so as to reduce fuel-air mixture velocity and produce a low velocity, stable carryover flame that reduces the tendency of the main flame to lift.
