This application discloses a circularly tangential flat
flame nozzle and its combined array structure, relating to the field of
nozzle structures. It includes a
nozzle body with an inlet end and an outlet end at both ends. Gaseous oxidant enters from the inlet end and exits from the outlet end. The inlet end has a circular cross-section, and the projection of the outlet end along the axis of the nozzle body's inlet end is elliptical. The outlet end is arc-shaped, with its axis perpendicular to the plane containing the major axis of the
ellipse and the inlet end axis, and the arc axis intersects with the inlet end axis. This provides a sufficiently large scattering area, allowing the process gas and oxidant to mix thoroughly at the nozzle outlet, improving the
combustion efficiency of the process gas, and forming a uniform temperature distribution in the reactor
combustion chamber.
