The main throttle valve on a main propulsion turbine admits steam directly into the __________.
⢠Function of the main throttle valve in a steam turbine propulsion system ⢠Order of steam flow path: from boiler, through valves, into turbine components ⢠Purpose of a steam chest and a nozzle diaphragm in controlling and directing steam
⢠Trace the path of steam starting at the boiler and think stepâbyâstep: after passing through the main throttle valve, where does steam need to go before it can effectively act on the blades? ⢠Which componentâs job is to receive highâpressure steam and distribute it evenly, and which componentâs job is to convert that pressure into highâvelocity jets? ⢠Which option would be too far downstream in the flow path for the throttle valve to feed directly, and which option is more of an intermediate space/volume rather than a moving part?
⢠Be clear on the sequence: boiler stop valve â main throttle valve â next component â nozzles â blades â exhaust path ⢠Identify which choice represents a volume or chamber that collects steam, not a moving part or a small passage ⢠Verify which component is specifically designed to distribute steam uniformly before it expands through nozzles.
