Definitions

  • the liquid may be a liquid fuel and/or water.
  • fuel port 216 may be defined by interior wall 217 at shoulder 219.
  • fuel may be distributed or injected into mixing chamber 224 where the fluid velocity in the chamber is relatively low (e.g., the fluid velocity in an upstream portion of mixing chamber 224 may be lower than the fluid velocity in mixing chamber 224 near transition zone 224').
  • the fuel distribution G' demonstrates greater fuel penetration as compared to fuel distribution G, as shown in FIG. IB. In this regard, fuel distribution G' illustrates that the fuel propagates across the entire volume of mixing chamber 224. This greater penetration provides for lower fuel density, a more suitable fuel-air mixture, and better ignition efficiency.

Abstract

Dans divers modes de réalisation, l'invention concerne une buse à deux combustibles (200) destinée à être utilisée dans une turbine à gaz. La buse peut être configurée pour fournir un gaz et un liquide. La buse à deux combustibles (200) peut comprendre une paroi intérieure (217). La paroi intérieure (217) peut comprendre un épaulement (219). L'épaulement (219) peut comprendre un ou plusieurs orifices de gaz (216). Un gaz peut être distribué à travers les orifices de gaz (216) et pénétrer dans une zone de mélange.
