Fuel/air premixer for gas turbine combustor |
摘要 |
A fuel/air premixer for use in a gas turbine improves the atomization performance and mixing performance of the fuel by guiding an air so as to flow in an outward radial direction. A flow-deflecting tubular body having an annular cross section is disposed on the inside of and coaxially with a liquid film-forming body of an airbiast atomizer nozzle disposed at the inlet portion of a premixing tube. The outer peripheral surface of the flow-deflecting tubular body has a wall surface which increases in outer diameter toward the tip end of a first annular passage. The inner peripheral surface of the flow-deflecting tubular body has a form in which the inner diameter has a minimum to form a contracted portion, and then increases dramatically toward the tip end.
