In this combustion burner, the air supply pipe has a rectangular constriction section, and after the constriction section, the passage is divided into two for distribution and connection to an inner cylinder for primary air and an outer cylinder for secondary air. A partition wall is provided, and a rectangular distribution valve for distributing the air passing through the constriction section is disposed at the tip of the partition wall, and a primary air supply passage and secondary air are divided into two by the constriction area and the partition wall. A combustion burner characterized in that the passage areas of supply passages are made equal.

Claims

[Scope of utility model registration request]

In a combustion burner, an inner cylinder for primary air and an outer cylinder for secondary air are arranged concentrically around a fuel supply pipe with a nozzle at the tip, and combustion air is supplied from a direction perpendicular to the fuel supply pipe. The tube has a rectangular constriction section, and after the constriction section, a partition wall is provided to divide the passage into two and connect the primary air inner cylinder and the secondary air outer cylinder. A rectangular distribution valve is provided to distribute the air passing through the constriction part, and the area of the constriction part and the passage area of the primary air supply passage and the secondary air supply passage divided into two by the partition wall are made equal. Characteristic combustion burner.
