Abstract
An exhaust pipe (A) of a turbine has a housing (1). The walls of the housing (1) define a flow duct (2) accommodating therein a baffle (5) whose housing baffle (5) has a side surface (6) which is the surface of a body of revolution about an axis coinciding with the axis (7) of the turbine. The surface (6) has an inlet portion (8) having to a radius shorter than the outer radius R of the blades (3) of the runner (4) of the turbine. Mounted within the flow duct (2) are guides (10) supporting the baffle (5) which is adjustable along the guides (10) relative to the housing (1) of the exhaust pipe (A) axially and/or transversely of the axis (7) of the turbine.
Claims19
An exhaust pipe for a turbine having a given axial thermal expansion and a last stage including a runner terminating outwardly in blades, comprising:
- a housing having walls defining a flow duct;
- a baffle in said duct;
- said baffle having a side surface in the form of a surface of revolution and an inlet portion having a radius shorter than the outer radius of said blades of said runner;
- said baffle having the longitudinal axis thereof substantially coincident with the axis of said turbine;
- and
- guide means mounted in said duct for adjustably supporting said baffle relative to said housing in a direction axial and transversal of said axis of said turbine.
An exhaust pipe for a turbine having a given axial thermal expansion and a last stage including a runner terminating outwardly in blades, comprising:
- a housing having walls defining a flow duct;
- a movable baffle in said duct;
- said baffle having a side surface in the form of a surface of revolution and an inlet portion having a radius shorter than the outer radius of said blades of said runner;
- said baffle having the longitudinal axis thereof substantially coincident with the axis of said turbine;
- and
- movable guide means mounted in said duct for adjustably supporting said baffle relative to said housing for moving said baffle in a direction relative to said axis of said turbine.
In an exhaust pipe for a turbine having a given axis and a housing with walls defining a flow duct accommodating therein a baffle;
- said baffle having a side surface in the shape of a surface of a body of revolution and a longitudinal axis coinciding with the axis of said turbine,
- said baffle having an inlet portion of a radius shorter than the outer radius of the blades of the runner of the last stage of the turbine, the improvement wherein
- said flow duct of said exhaust pipe accommodates therein guides adjustably supporting thereon said baffle relative to said housing of said exhaust pipe, said guides being movable in at least one direction axially and transversely of said axis of said turbine.
