An alcohol group boiloff fuel-reforming burner belongs to the industrial burning device technical art. A crust (2) has an inlet branch(1), and the inlet branch(1) is provided with a screw thread and a transverse fuel gas spout one (6); a spinning disc(5) and a direct current disc(4) are arranged on the position of the screw thread, which divide the crust into a First Mixed Room(11) and a Second Mixed Room(12); a main fuel gas nozzle is arranged on the top of the inlet branch(1), and the main fuel gas nozzle has a transverse fuel gas spout two(7) and a portrait fuel gas nozzle three(8); an electric igniter(3) is arranged in the crust(2); the burning gas enters from the inlet branch(1), and the air enters from the hot-air inlet(14), and the spinning disc spout(17) supplies the air in conjunction with the direct current disc(16), premixing part of the fuel gas and the air; the utility model adopts that the screw thread adjusts the size of the mix room, and the fuel gas spout is collocated along both the transverse and portrait direction, thus realizing the sufficient mixing of the fuel and the combustion air and the adjusting of the length of flame; the burning is high in efficiency with little burning pollutant discharge.
