Atmospheric-pressure superconducting pipe type heating furnace

The utility model relates to an atmospheric-pressure superconducting pipe type heating furnace which has the technical scheme that a fire tube and an explosion-proof port are arranged at the bottom of an inner cavity of a shell body, and a heat exchanger and a chimney are arranged at the upper part; the heat exchanger adopts a snake-shaped oil coil; the space between a straight-flowing section of the snake-shaped oil coil and a superconducting sleeve is full of superconducting heat mediums; one end of the snake-shaped oil coil is provided with an oil and water inlet and outlet opening; a radiation and convection chamber is arranged among the shell body and patterned plates at the two ends of the shell body; and the superconducting sleeve is positioned in the radiation and convection chamber. The atmospheric-pressure superconducting pipe type heating furnace has the beneficial effects that the heat mediums in the superconducting sleeve quickly transfer the heat to the snake-shaped oil coil and mediums to be he
