Abstract
A turbine installation is adapted for enhancing the level of dissolved gas in water flowing therethrough. The installation comprises a water passageway for containing turbine components including a turbine runner. The water passageway extends from an upper elevation source of water to a lower elevation discharge region. The turbine runner is disposed in the passageway so that water flowing therethrough impinges on the runner. The runner includes a plurality of blades extending from the hub at circumferentially spaced intervals. Each blade is defined by a pressure surface, an oppositely facing suction surface, a leading edge and an spaced apart trailing edge. At least one of the blades has an integrally formed gas passage extending from a gas inlet aperture in the hub to the trailing edge. The installation further comprises an oxygen containing gas source coupled to the gas inlet aperture and a control system for controlling the flow of gas to the gas inlet aperture to regulate the dissolved oxygen level in the water. A method of increasing the dissolved oxygen level in such a turbine installation is also disclosed.
