Abstract
The object of the invention is to produce a method, for operating a gas turbine installation combustion chamber with liquid fuel, by means of which the NO.sub.X figures obtained when liquid fuel is employed are similar to those for gaseous fuels. The size of the burner is then also reduced. It is also an object of the invention to provide a corresponding appliance for carrying out the method. This is achieved in accordance with the invention in that the liquid fuel (38) is evaporated in at least two steps in a separate evaporative reactor (12). In this arrangement, the liquid fuel (38) is first atomized to a fuel vapor/liquid fuel mixture (61) by direct heat exchange with a first heat exchange medium (21) and is instantaneously evaporated in this process. The evaporation of the remaining residue of the liquid fuel (38) then takes place by indirect heat exchange with a second heat exchange medium (51). For this purpose, an evaporative reactor (12) is arranged vertically upstream of the combustion chamber (2) and is connected to it, which evaporative reactor (12) accommodates, at its inlet end, a dual-fluid nozzle (22) connected both to a liquid fuel line (19) and to a supply line (2…
