PURPOSE:To unnecessitate impact plates, uniformly distribute a bypass steam and contrive to efficiently treat the steam, by a method wherein orifice holes provided in turbine bypass steam introducing pipes are skewly provided in symmetry on upper and lower sides, and jet of the steam ejected are caused to collide against each other in the exterior of the pipes. CONSTITUTION:The turbine bypass steam 3 entering steam-introducing pipes 5 are ejected through the orifice holes 6 to constitute the jets 4 of the steam, which are diffused by colliding against each other in the exterior of the pipes 5. Steam jets 4' reduced in energy due to diffusion pass through both side passages 17 and a central passage 18, and the steam is condensed at a cooling pipe group 13. Since the jets 4 of the steam ejected is converted into the steam jets 4' low in energy through the collision, effects on the internal structures of the condenser such as cooling pipe group 13 are reducd, and reliability is enhanced. In addition, impact plates are unnecessitated, the height of the condenser is prevented from being increased as the size of the steam-introducing pipes 5 is increased, the condenser can be made to be compact, so that it is made to be advantageous from an economical point of view, a flow of turbine exhaust 1 is hindered, and efficiency of the condenser is prevented from being lowered. |
