ABSTRACT:
A premixing swirling burner including a burner body having a swirling member at one end for causing fuel introduced into the burner body to flow in vortical form through the swirling member, a burner outer frame mounting the burner body and communicated with an air line for introducing air into the burner body, and a cylindrical member located in the burner outer frame for enclosing the burner body, with an air passage being defined between the inner periphery of the cylindrical member and an outer periphery of a portion of the burner body. A premixing chamber is defined between an outer periphery of a central portion of the burner body and an inner periphery of the cylindrical member for providing a fuel-air premix flowing toward the swirling member. A fuel chamber introduces fuel into the interior of the burner body, and a fuel ejection nozzle is located along an outer surface of the central portion of the burner body. A channel defined between the inner periphery of an end portion of the cylindrical member and an outer peripheral portion of the burner body formed an inlet for the premixing chamber has a cross-sectional area smaller than a cross-sectional area of the air passage.
