Double shaft gas turbine, has bars arranged along circumference of bearing housing and extend via circular intermediate channel into space between outer circumference surface of housing and inner circumference surface of housing wall

摘要

The turbine has a circular intermediate channel (17) connecting a gas passage outlet (15) with a gas passage inlet (16). A bearing (19) supports a rotor (18) of a high pressure turbine (12) and is fit at a bearing housing (20). Bars (23) are arranged along the circumference of the housing and extend via the channel into a space between an outer circumference surface of the housing and an inner circumference surface of a housing wall (21). The channel has a bar covering, via which the bars extend and serve as guide vanes of a stage of a low-pressure turbine (13).
