摘要： PROBLEM TO BE SOLVED: To provide an air assisted simplex fuel nozzle easy in an adjustment.
SOLUTION: An air assisted simplex spray nozzle assembly for a fuel burner has a nozzle body 20 having the upstream end 22 and the downstream end 24, an air inlet 38 and an adapter member 30 engaging with the upstream end of the nozzle body and concentrically arranged for the nozzle assembly, and an air cap 40 arranged by covering the downstream end of the nozzle body. This nozzle assembly includes a fuel circuit and a first air circuit. The fuel circuit introduces fuel toward a fuel outlet of the nozzle body, and extends up to the fuel outlet by passing through the nozzle body from the fuel inlet of the adapter member. The first air circuit introduces assist air toward the fuel. The first air circuit extends by passing through a clearance 42 between an air cap and the nozzle body from the air inlet of the adapter member, and merges with the fuel discharged from the nozzle body. The assist air is supplied to the first air circuit by an auxiliary pump.

摘要： PROBLEM TO BE SOLVED: To provide a lean direct injection atomizer capable of lowering a combustion unstable level, capable of enhancing an atomizing condition, capable of enhancing an air-fuel mixture ratio, capable of reducing generation of a contaminant, capable of restraining smoke emission, and capable of enhancing a margin for interruption of lean combustion.
SOLUTION: This atomizer is provided with a lean direct injection fuel nozzle for a gas turbine, and the fuel nozzle is provided with a radially outside main fuel distributor. The main fuel distributor is provided with a main inside air swirler 58 formed partially of a main inside air passage 66 having a radially inner wall 68 provided with a divergent downstream face, an intermediate air swirler 70 for supplying a cooling air flow along the downstream face of the radially inner wall 68 of the main inside air passage 66 provided in an inside of the main inside air swirler 58, and a radially inside pilot fuel distributor provided in an inside of the intermediate air swirler 70.
