MULTI-FUEL TURBINE COMBUSTOR, MULTI-FUEL TURBINE COMPRISING SUCH A COMBUSTOR AND CORRESPONDING METHOD

摘要

Combustor (50) for use in a turbine (100). The combustor (50) comprising a multiple fuel atomizers (10) which has a gas inlet for feeding gaseous fuel as first combustible into an inlet zone of the atomizer, an air inlet for feeding compressed air into the inlet zone, and an orifice for injecting a liquid fuel as second combustible into the inlet zone. The atomizer comprises a diffuser for emitting a gas stream at an exit side. The atomizer (10) is arranged with respect to a combustion chamber of the combustor (50) so that the exit side of the diffuser points in a tangential direction relative to the combustion chamber. The combustor (50) comprises an outlet duct (51) for discharging an exhaust gas produced by a combustion process of the gas stream inside the combustion chamber. The exhaust gas drives a turbine (63).

主权项

1. A reverse flow annular combustor for use in a turbine, said combustor comprising at least one air-blast atomizer operating on a combustible, wherein the air-blast atomizer is a multiple fuel atomizer which has
a gas inlet for feeding gaseous fuel as first combustible into an inlet zone of the atomizer, an air inlet for feeding compressed air into the inlet zone, an orifice for injecting a liquid fuel as second combustible into the inlet zone or into an area close to the inlet zone, and a diffuser for emitting a gas stream at an exit side comprising said gaseous fuel, compressed air and said liquid fuel,
said atomizer being arranged with respect to a combustion chamber of said combustor so that the exit side of said diffuser points in a tangential direction relative to said combustion chamber, and wherein said combustor comprises an outlet duct for discharging an exhaust gas produced by a combustion process of said gas stream inside said combustion chamber.
