Fuel atomizing device and flame tube head structure having the same

Abstract

The invention discloses a fuel atomization device and a flame tube head structure having the same, comprising: a vortexer fixing component, a vortexer component is arranged in an inner channel of the vortexer fixing component, and a vortexer component is arranged between the vortexer component and the vortexer fixing component An installation limit ring is installed, and the installation limit ring is used for floating installation of the vortex generator assembly relative to the vortex generator fixing assembly, and a fuel nozzle is inserted into the inflow end of the channel in the vortex generator assembly. A first swirl hole group is arranged on the wall surface of the vortexer assembly, and the first swirl hole group is used to introduce the external airflow into the inner channel of the vortexer assembly, and form a high-speed swirling airflow that rotates at a high speed along the circumferential direction, and then The high-speed rotating airflow cuts the fuel injected by the fuel nozzle into tiny oil droplets. A second swirl hole group is arranged in the wall surface of the vortex device fixing assembly, and the second swirl hole group is used to introduce the external air flow into the channel of the flame tube head, and form a circumferential rotation and close to the flame tube head. The rotating covering gas film flowing on the inner wall surface.

Description

technical field [0001] The present invention relates to the technical field of gas turbine engine combustion chambers, and in particular, to a fuel atomization device. In addition, the invention also relates to a flame tube head structure with the fuel atomizing device. Background technique [0002] The fuel atomization device is an important component of the combustion chamber of the gas turbine engine. Each turbo power machine has at least one nozzle to provide fuel, and under the action of the atomization device, an oil mist field is formed to burn, and the working performance of the fuel atomization device is good or bad. It directly affects the ignition performance, combustion performance and pollution emission performance of the combustion chamber. [0003] figure 1 It is a fuel atomization device currently in use. The fuel atomization device consists of a nozzle and a stabilizer. The stabilizer and the flame tube are fixed by welding. The stabilizer is a bowl-shaped...
