<p>A combustion head comprises a base (10), a primary opening (20) and a fuel nozzle (40), wherein the base (10) is a base structure of the combustion head. The primary opening (20) is an opening located at the rim of the base (10). The fuel nozzle (40) is located at the middle of the base (10) having a fuel distributor hole (42) as a fuel exit for the fuel passing through the base (10). The fuel distributor hole (42) is perforated in an inclined manner of 10-80 degree. The combustion head further comprises an auxiliary opening (30) located at the rim of the base (10). The size of the auxiliary opening (30) is smaller than the primary opening (20). The combustion head decreases an operating cost and ensures a complete combustion.</p>
