| 摘要 |
Apparatus and method for a combustion turbine engine are provided. The apparatus includes a fuel-injecting lance (12) to convey a liquid fuel to a downstream end (16) ofthe lance. At least onejet in cross- flow injector (18) may be disposed at the downstream end ofthe lance, and includes an ejection orifice (20) responsive to eject a liquid jet (22) of the fuel. A plurality of surface irregularities (28, 29, 30, 50, 52, 54) is disposed at least on a portion of a wall (32) of the fuel-injecting lance exposed to the flow of air and proximate to the ejection orifice (20). The plurality of surface irregularities be arranged to interact (e.g., turbulent interaction) with the flow of air to promote breakage of the ejected liquid jet of fuel compared to an injector lacking such surface irregularities. |
