In a method for the operation of a power station installation which essentially comprises a compressor (4), a combustion unit and a turbine (12), the combustion unit comprising a conditioning stage for at least part of the combustion air and a combustion chamber, a portion (13a) of the compressed air (13) from the compressor (4) is passed through the conditioning stage and there first of all mixed with a quantity of fuel (14a). This mixture then passes into a generator (8), in which at least hydrogen is fractionated, this hydrogen then being used in the combustion chamber. The combustion chamber comprises a start-up burner (1), a catalytic stage (2) and a downstream second combustion stage (3). Both the air/fuel mixture (16a) fractionated in the generator (8) and the further compressor air (13) enter the combustion chamber, in which interdependent combustion occurs between the combustion units acting there, relative to the running up of the installation, for the purpose of minimizing pollutant emissions.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.] A method of operating a power station installation, the power station comprising at least one compressor, at least one combustion unit and at least one turbine, the combustion unit comprising a combustion chamber and a conditioning stage, connected upstream of the combustion chamber, for at least part of the combustion air, the method comprising the steps of:directing a portion of the compressed air through the conditioning stage,mixing a quantity of fuel with the portion of compressed air andreforming the fuel and air mixture in a hydrogen generator,directing the reformed gases into the combustion chamber, wherein the remaining compressed air likewise flows into the combustion chamber, andoperating a start-up burner of the combustion chamber on an individual basis using part of this air, and operating a catalytic stage acting upstream of the start-up burner and likewise belonging to the combustion chamber with a remaining part in conjunction with the reformed mixture from the conditioning stage, wherein the total combustion air heated by the catalytic stage and the start-up burner flows into a downstream second combustion stage, in which a further combustion is carried out to generate hot gases.
