Abstract
A turbine installation for regulating the levels of dissolved gas such as oxygen in water flowing therethrough. The turbine installation comprises a runner rotatably mounted within a stationary casing. The runner includes a crown, a band, and a plurality of blades extending between the crown and the band. The stationary casing includes a head cover disposed concentric with and spaced from the crown and a discharge ring concentric with and spaced from the band. At least one annular seal is disposed between the casing the runner to limit water leakage into a mixing chamber formed between the relatively rotating casing and runner. A gas supply is in fluid communication with the mixing chamber for supplying a flow of a gas thereto, and a control system controls the flow of gas into the mixing chamber for regulating the level of dissolved gas in the water discharged from the turbine installation.
