Combustion burner

A combustion burner comprising:

• an air supply case connected to an air supply mouth formed at a portion adjacent a rear end thereof to a tip portion thereof and formed in the shape of a pipe, supplying air from an air supply equipment;
• a nozzle body formed in the shape of a pipe and attached so as to cover a tip portion of the air supply case, having a concave portion as a jet nozzle formed in a center part of the nozzle body and formed in the shape of a conical trapezoid;
• a fuel nozzle installed into the nozzle body so as to supply air from the air supply case from the air jet hole, placed between the tip perimeter part of the fuel nozzle and the jet hole, having a fuel supply passage which is formed in the shape of a conical trapezoid and supplies air from a tip portion thereof;
• a plurality of air guide holes air guide holes provided between an outer circumferential portion of the fuel nozzle and the nozzle body so as to supply spiral air from the air jet hole;
• a fuel supply support member installed into the fuel supply passage and supplies fuel from four fuel supply holes at an opposite spiral air current from the tip end of the fuel nozzle compared with the air current supplied from the air jet hole;
• and
• four fuel supply pipes, one end part of the fuel supply pipes connected to the fuel supply holes, another end part thereof connected to a fuel supply which supplies waste oil, heavy oil and the like and water supply which supplies water, dirty water and the like, projecting outwardly from the part adjacent the rear end part of the air supply case.

A combustion burner comprising:

• an air supply case formed in the shape of a cap, having a pipe which supplies air from an air supply equipment;
• a nozzle body formed in the shape of a pipe and attached so as to cover an opening of the air supply case, having a concave portion as a jet nozzle formed in a center part of the nozzle body and formed in the shape of a conical trapezoid;
• a fuel nozzle installed into the nozzle body so as to supply air from the air supply case from the air jet hole, placed between the tip perimeter part of the fuel nozzle and the jet hole, having a fuel supply passage which is formed in the shape of a conical trapezoid and supplies air from a tip portion thereof;
• a plurality of air guide holes air guide holes provided between an outer circumferential portion of the fuel nozzle and the nozzle body so as to supply spiral air from the air jet hole;
• a fuel supply support member installed into the fuel supply passage and supplies fuel from at least two fuel supply holes at an opposite spiral air current from the tip end of the fuel nozzle compared with the air current supplied from the air jet hole;
• and
• at least two fuel supply pipes, one end part of the fuel supply pipes connected to the fuel supply holes, another end part thereof connected to a fuel supply which supplies waste oil, heavy oil and the like and water supply which supplies water, dirty water and the like.
