摘要

A removable flame heat transfer regulating apparatus having an inner hollow shell surrounded by an outer wall is incorporated with a burner having improved burner ports for a gas stove to increase the flame heating efficiency in cooking. The shell is an ascending wall including air passages of openings therethrough its upper and lower parts, wherein openings are densely distributed to the lower part. The outer wall has air passages of openings therethrough, and extensions spaced apart projecting upwardly including one serving as a heat shield to prevent heating of a utensil handle. The apparatus is positioned to surround an upper section of the burner, wherein each improved burner port of opening includes a smaller section having a smaller inlet connected to a larger expanding section having an ascending interior top surface and a larger outlet.
