The removable apparatus includes an outer wall and improved inner hollow shell which are both positioned on the cooktop of a gas stove to surround an upper section of a burner, where the outer wall surrounds the hollow shell. The improved inner hollow shell is a closed preferably circular hollow member having a larger section connected to a smaller section thereby forming a valley of space to retain dripping liquid substance in cooking. A plurality of openings penetrate through the larger section, wherein more openings are located to its low part. The outer wall has multiple openings which evenly penetrate therethrough. Many extensions projecting upwardly are spaced apart onto a top edge of the outer wall to support a cooking utensil. The apparatus is served as a flame heat transfer regulator for achieving high heating efficiency in cooking and a liquid substance retainer for easily maintaining the cooktop clean.
