Abstract

A fire hole part structure of a gas burner, which is constructed to be manufactured at a low cost, can improve flame stability, and can prevent incomplete combustion due to the length of flame. The structure is provided to a premixing ignition burner, which is installed to apply heat to a heat exchanger of a boiler, and includes fire hole pieces which are installed parallel to one another in mounting openings of a burner body, and each of which is defined with fire holes at regular intervals. An upper wall of at least one of the fire hole pieces is bent or curved to extend in at least two directions, and the fire holes are defined through respective surface portions of the upper wall, which extend in different directions, to face different directions.
