Abstract

A burner having a primary nozzle, a secondary nozzle and a tertiary nozzle, a partition wall partitioning the secondary nozzle and the tertiary nozzle and a flow path change member provided thereon. The partition wall is formed so as to be movable in parallel to the burner axis to control jetting speeds and flow rates of secondary air and tertiary air whereby it is possible to cool the burner constituent members while reducing NOx. The partition wall is composed of a fixed wall and a movable wall. A bypass passage is formed through which tertiary air in the tertiary nozzle bypasses the tertiary nozzle to flow into the secondary nozzle or the primary nozzle.
