The invention relates to the technical field of combustion chamber structures, in particular to a low-nitrogen-hydrogen combustion chamber structure. The burner comprises a flame tube, an ignition structure is arranged in the center of the head of the flame tube, a premixing gas inlet structure is arranged on the side face of the flame tube, the premixing gas inlet structure is communicated with an inner cavity of the flame tube, and the premixing gas inlet structure can introduce premixed combustible gas into the inner cavity of the flame tube. Combustion is organized by means of rotational flow flame stabilization and staged combustion of combustible premixed gas in the axial direction of the combustion chamber, a safe and stable head flame source is provided by an ignition structure, and the combustion equivalence ratio of the head of a flame tube is reduced; meanwhile, the equivalence ratio of combustible premixed gas entering along the axis of the flame tube can be accurately controlled, and hydrogen fue
