摘要： A gas turbine combustor comprises an inner cylinder provided with louvers in an outer periphery thereof, defines a head combustion chamber and a main combustion chamber located downstream of and greater in diameter than the head combustion. An outer cylinder surrounds the inner cylinder and defines an air passage therebetween. A first burner communicates with the head combustion chamber and supplies air with gaseous fuel, and a second burner being disposed in the air passage near the head combustion chamber and supplying air and gaseous fuel into the main combustion chamber. The second burner is formed with a plurality of air inlets by a plurality of vanes which are disposed in an annular passage and which swirl the air, and with gaseous fuel jet ports near the inner peripheries of the air inlets. When the flow rate of the supplied fuel is small, the fuel flows along an inner-peripheral surface of the second burner, and when the flow rate is large, the fuel from the air inlets moves from the inner-peripheral surface toward the outer-peripheral surface of the second burner so as to be mixed well with the air supplied into the main combustion chamber. Thus, the production of NO.sub.x, CO, HC etc. can be decreased over the whole operating range of the turbine.

摘要： 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.
