Double-head strong-rotational-flow low-nitrogen combustion head

The invention discloses a double-head strong-rotational-flow low-nitrogen combustion head which comprises two premixing cylinders arranged in parallel, an air inlet pipe is arranged in the air inlet end of each premixing cylinder, one or more mixing pieces are arranged outside each air inlet pipe, the air inlet pipes are installed in the premixing cylinders through the mixing pieces, flame stabilizing cylinders are arranged in the air outlet ends of the premixing cylinders, and the flame stabilizing cylinders are arranged in the air outlet ends of the premixing cylinders. A spinning disk is arranged outside the flame stabilizing cylinder, the flame stabilizing cylinder is installed in the premixing cylinder through the spinning disk, and a flame stabilizing disc is arranged at the gas outlet end of the flame stabilizing cylinder. The combustion head is compact in structure, flames can deflect downwards under the action of the forward and reverse rotational flow pieces, and by means of the structure, on one ha
