Ammonia-hydrogen fusion zero-carbon burner

The invention discloses an ammonia-hydrogen fusion zero-carbon combustor which comprises a combustion chamber, a flue gas circulating pipeline, a graded preheating device, a heat pipe heat exchange device and a combustion-supporting gas rotational flow device. Through a strong rotational flow proportioning method, a combustion-supporting gas rotational flow device is arranged, and air distribution is improved in an arrangement mode of high and low rotational flow numbers and axial and longitudinal rotational flow numbers, so that mixing is enhanced; the heat of high-temperature flue gas is fully and efficiently utilized, the loss of high-quality heat energy is avoided to a certain extent, the effects of energy conservation and emission reduction are achieved, and the requirements of a user for energy conservation, cleanness, safety and stability in combustion of ammonia gas can be met; hydrogen-rich gas is adopted as fuel, H2 diffusion on-duty flames are arranged in the center of the combustion chamber, and t
