CORROSION PREVENTING DEVICE FOR CONDENSER

摘要

PURPOSE:To provide a corrosion-proof characteristic at a vapor phase part and a water contact part by a method wherein a spray nozzle capable of performing a uniform spraying of H2O2 not only over the hot well of a condenser, but also over the entire inner part of the condensor is arranged over the vapour phase part. CONSTITUTION:H2O2 fed from a spray nozzle 18 is expanded in a wide range and dropped into a hot well 3 while being mixed with major vapor and two- phase flows under its atomized condition. A part of this H2O2 may wet uniformly a side wall of a condenser 2 and the surface of an inner structure, so that they may be prevented from being corroded. In addition, H2O2 flowed into the hot well 3 is mixed with the condensed water and then the water contact part of the hot well 3 may be prevented from being corroded.
