Patent ID: 7846260

Claim:
An on-line automatic flushing and cleaning apparatus for a condenser in a turbine generator comprising: a high speed water jet position in the condenser to reach each copper tube or titanium tube across a tube plate in the condenser; a longitudinal moveable extension support beam positioned in the condenser, the water jet mounted at one end of the support beam; a rotatable movable rotating support beam positioned in the condenser and mounted at the other end of the extension support beam, the extension support beam longitudinally movable from the rotating support beam; a computer programmed polar coordinating unit, positioned outside the condenser, that converts a rectangular coordinate position (x, y) of each tube of the tube plate of the condenser in the turbine generator into a polar coordinate position (R, f) and outputs a control signal in polar coordinates; an angle rotating control motor, positioned outside the condenser, that receives the control signal from the coordinating unit in polar coordinates and rotates the rotating support beam based on the polar coordinates by means of a related transmission and an rotating driving shaft which is connected at one end of the angle rotating control motor and at the other end to the rotating support beam; a radius moving control motor positioned outside the condenser, that receives the control signal from the coordinating unit in polar coordinates, and longitudinally moves, in a radial direction, the extension support beam by means of a related transmission and an extension driving shaft which is connected at one end to the radius moving control motor and at the other end to the extension support beam such that the water jet moves directly from polar coordinates calculated for each tube by the coordinating unit and the apparatus works in turbulent water flow conditions so that the flushing and cleaning occurs while the condenser is on-line.
