摘要

A premixer (10) is provided and includes a peripheral wall (20) defining a mixing chamber (21) therein through which a flow path (22) for a fluid (25) is defined, a nozzle including an annular splitter plate (70) disposed in the flow path (22) within the mixing chamber (21), the splitter plate (70) including a trailing edge (91) defined in relation to a predominant direction of fluid flow along the flow path (22) and being formed to define a fuel line (100) therein, which is receptive of oil fuel (101) and an annular array of fuel injectors disposed at the trailing edge (91), which are each fluidly communicative with the fuel line (100) and configured to inject at least the oil fuel (101) into the flow path (22) with the oil fuel (101) being substantially atomized upon injection or substantially immediately after the injection by interaction with the fluid flowing along the flow path.
