Abstract
At a low part load, and at idling of a vehicle machinery it is difficult to obtain a good fuel economy and acceptable emission rates. The amount of work for driving the compressor and the auxiliary apparatuses is considerable in a gas turbine, and in view of the conditions mentioned the combustor of the gas turbine is provided with two burners, of which one is dimensioned for a fuel quantity which merely corresponds to 'spare-flame' operation. An auxiliary motor means is included in the machinery and keeps, together with the 'spare-flame' operation. An auxiliary motor means is included in the machinery and keeps, together with the 'spare-flame' burner, the main rotor of the gas turbine running at idling and part-load. The auxiliary motor may be an electric motor, a pressure fluid motor, or a combustion engine. The compressor is provided with means for throttling the flow of air, and a control device operates this throttling means so it is effective during 'spare-flame' operation.
