  • Multi-valve arc inlet for steam turbine
    Patent number: 6386829
    Abstract: A steam turbine has multiple valves for introducing steam into a steam turbine. Each of the input valves introduce steam flow around the entire the 360 degree arc. The set of nozzles are each divided into a plurality of chambers. Each set of chambers extends around the full arc of the turbine. Each set has a valve. The chambers are designed so that all valves are open when the turbine is running at maximum output. The chambers are sized such that valve throttling losses are minimized when the turbine is at its normal operating condition.
