A film evaporator burner arrangement (1) is provided, having: a combustion chamber arrangement comprising a combustion chamber (2) for the conversion of a fuel-air mixture with the release of heat, which extends in the axial direction along a longitudinal axis (Z); a combustion air supply (5) for the supply of combustion air, which is configured such that the combustion air is supplied with a tangential flow component to at least one combustion air inlet (8) of the combustion chamber arrangement; a film evaporator surface (4) for evaporating liquid fuel originating from a fuel film (10), which is arranged at a rear wall (3) axially rearward of the combustion air inlet (8); and a fuel supply (9) for the supply of liquid fuel to the film evaporator surface (4).

A combustor assembly for a turbomachine includes a combustor housing defining a combustion chamber. The combustor housing includes an inlet portion, an outlet portion, and an axial axis extending between the inlet portion and the outlet portion. A first annular plenum is arranged at the inlet portion. The first annular plenum includes a first inlet and a first outlet. A second annular plenum radially spaced from the first annular plenum is arranged at the inlet portion. The second annular plenum includes a second inlet, a second outlet, a vortex inducing member arranged between the second inlet and the second outlet, and a fuel outlet. The second outlet includes a pre-filming surface that forms an annular ring of fuel that enters the second annular plenum through the fuel outlet and passes from the second annular plenum into a swirling fluid passing through the first outlet and the second outlet.
