Title:
燃料／空気の混合が改良されたスワーラ、燃焼器アセンブリおよびガスタービン
Document Type and Number:
Japanese Patent JP6805355
Kind Code:
B2
Abstract:
A swirler for creating a swirling fuel/air mix is presented. The swirler has vanes extending radially around a central axis of the swirler and positioned on an annular base. The swirler has mixing channels for mixing the fuel and the air. At least one mixing channel is defined by opposing walls of two adjacent vanes. At least one of the opposing walls includes a primary side injection opening for ejecting a stream of fuel into the mixing channel; and a secondary side injection opening which corresponds to the primary side injection opening and is for ejecting a jet of fuel into the mixing channel. The secondary side injection opening is positioned on the wall such that the jet from the secondary side injection opening creates turbulence, within the mixing channel, in the stream from the primary side injection opening. The turbulence increases mixing of fuel and air.
