Abstract (en)

[origin: WO2022078727A1] The invention relates to a radial turbine (20). The radial turbine (20) comprises: - a turbine housing (21) having a radial gas inflow channel (22); - a nozzle ring (23), which is disposed in the radial gas inflow channel (22); and - an annular cleaning device (10) for cleaning the nozzle ring (23). The annular cleaning device (10) is connected to a cleaning-agent feed (13) by means of an axially insertion-connectable supply line (12) such that, after or during the demounting of the nozzle ring (23), the annular cleaning device (10) can be removed from the turbine housing (21) in the axial direction. The invention also relates to a method for mounting a cleaning device for cleaning a nozzle ring of a radial turbine and to a method for demounting the cleaning device.
