Abstract
To provide an axial piston motor, comprising at least one main burner, which has at least one main combustion space and at least one main nozzle space, and comprising at least one pre-burner, which has at least one pre-combustion space and at least one pre-nozzle space, wherein the pre-combustion space is connected to the main nozzle space by way of at least one hot gas feed, that has improved operating and control characteristics even under non-steady-state operating conditions, the pre-nozzle space of the pre-burner has at least one auxiliary hot gas feed.
Claims15
An axial piston motor having at least one main burner, which has at least one main combustion space as well as at least one main nozzle space, and having at least one pre-burner that has at least one pre-combustion space as well as at least one pre-nozzle space, wherein the pre-combustion space is connected with the main nozzle space by way of at least one hot gas feed, further comprising an idle and at least one partial load, as well as a main nozzle of the main burner and a pre-nozzle of the pre-burner, wherein the main nozzle and the pre-nozzle are coupled with one another by means of a control unit.
A method for operation of an axial piston motor having at least one main burner and having at least one pre-burner, wherein an exhaust gas stream of the pre-burner is mixed into a main fuel stream of the main burner, comprising an idle and at least one partial load, wherein the main burner is ignited during a load jump from idle to a lowest partial load, using the main fuel stream, and wherein a pre-fuel stream of the pre-burner is reduced during the load jump, by at least half the amount of the main fuel stream.
A method for operation of an axial piston motor having at least one compressor stage, having at least one main burner and having at least one pre-burner, wherein the compressor stage feeds a main air stream to the main burner and a pre-air stream to the pre-burner, and wherein an exhaust gas stream from the pre-burner is mixed into a main fuel stream of the main burner, wherein a combustion air ratio between a pre-fuel stream and the pre-air stream as well as a combustion air ratio between the main fuel stream and the main air stream can be adjusted in one stage.
A method for operation of an axial piston motor having at least one main burner that has at least one main combustion space as well as at least one main nozzle space with a main fuel stream, and having at least one pre-burner that has at least one pre-combustion space as well as at least one pre-nozzle space with a pre-fuel stream, wherein the pre-combustion space is connected with the main nozzle space by way of at least one hot gas feed, and having an air stream that has a main air stream for the main burner as well as a pre-air stream for the pre-burner, wherein during idle and/or a partial load of the axial piston motor, but at least during a load jump from idle to a lowest partial load, at least one secondary air stream is taken from the air stream, and the secondary air stream is fed into an exhaust gas stream downstream from and/or within the main combustion space.
