摘要

PURPOSE: An apparatus for detecting water leaked from a main tube of a heat recovering steam generator is provided to detect an initial water leakage by installing an alarm lamp notifying a worker of the water leakage. CONSTITUTION: A water leakage detection apparatus includes a movable port(9), a pressing plate(16), and a fixing supporter(10). The movable port(9) is installed in a case(50), which is individually installed at lower end of each tube block group. A lower surface of the movable port(9) is supported by an absorber. A cutting section is formed at both sides of the movable port(9). A guide rail(12) is fixedly attached to a center of an outer peripheral portion of the pressing plate(16). A ball installed in a slot of the guide rail(12) is fixedly provided at the fixing supporter(10).
