Problems solved by technology
However, the LPP combustion method has certain limitations: cold start is difficult, easy to temper, easy to spontaneous combustion, and combustion is unstable
Multi-point oil supply can effectively ensure the uniform distribution of the oil mist field and local low equivalence ratio, and can ensure the combustion and emission performance of the engine at full power, but the disadvantages are complex structure, increased weight, increased control difficulty, and poor reliability

A lean oil portion pre-mixing pre-evaporation homogenizing oil feeding device comprises a straight section evaporation chamber, a bluff body evaporation chamber connected with the straight section evaporation chamber, fuel oil nozzles arranged in the straight section evaporation chamber and oil pipes connected with the fuel oil nozzles. The lean oil portion pre-mixing pre-evaporation homogenizing oil feeding device is of a circle structure, the fuel oil nozzles are evenly arranged in the circumferential direction, are located in the straight section evaporation chamber and jet fuel oil downstream in the axial direction, and the oil pipes are of a lobe shape in a circumferential direction. According to the lean oil portion pre-mixing pre-evaporation homogenizing oil feeding device, fuel oil mixing gas is fed in the circumferential direction and the height direction of a combustion chamber, lean oil combustion is formed in a main combustion, and the target of low emission is achieved.
Description
Technical field: [0001] The invention relates to a premixed pre-evaporation homogeneous oil supply device for lean oil parts, in particular to a premixed pre-evaporation homogeneous fuel supply device for lean oil parts used in civil aviation engine combustion chambers and ground gas turbine combustion chambers, belonging to Gas turbine low emission technology field. Background technique: [0002] In the field of civil aviation, the International Civil Aviation Organization (International Civil Aviation Organization, ICAO) has successively formulated CAEP1 (1986), CAEP2 (1996), CAEP4 (2004), CAEP6 (2008) and CAEP8 (2010). regulations on emission standards. In order to make the emissions of aero-engines comply with the regulations of the International Civil Aviation Organization (ICAO) on pollutant emissions, the requirements for the emission performance of the combustion chamber are becoming increasingly stringent, especially for the limitation of NOX. [0003] During the ...
