Claims

[Claims for Utility Model Registration] 1. A flame port 5 is provided that spouts a mixed gas of gas fuel and primary air for combustion upward, and secondary combustion air from an electric fan 12 is provided in a combustion space 6 for the flame port 5. A secondary air supply path 13 is provided to supply a secondary air supply path 13, and the combustion surface forming wall body 3 extending upward from the flame port 5 is placed in an inclined or vertical position where the upper side is further away from the upwardly extending portion A of the flame port 5. The discharge port 14 of the secondary air supply path 13 is provided in the combustion surface forming wall 3 along an imaginary line extending upward from each end of the flame port 5 on the surface of the wall 3. A gas burner formed continuously or intermittently, wherein the combustion surface forming wall 3 is formed in a cylindrical shape, and the flame port 5 and the discharge port 1 for supplying secondary air are formed.
4 are distributed over the entire circumference of the cylindrical combustion surface forming wall 3 to form a combustion surface 3a on the combustion surface forming wall 3 that covers almost the entire circumference. 2. The gas burner according to claim 1, wherein the combustion surface forming wall 3 has a cylindrical shape with a flared tip, and the combustion surface 3a is an inner surface of the wall 3.
