20130327128 | LEAKAGE INSPECTION METHOD OF HEAT EXCHANGER - When a liquid level is changed even though an inflow of a heat medium into a specific heat transfer tube bundle is stopped, it is determined that there is no abnormality in the heat transfer tube bundle in which the inflow of the heat medium is stopped and then another heat transfer tube bundle is inspected. Next, when the inflow of the heat medium into the specific heat transfer tube bundle is stopped not to cause the change in the liquid level, it is determined that there is an abnormality in the heat transfer tube bundle to which the inflow of the heat medium is stopped. Thus, it is possible to determine that there is an abnormality in the heat transfer tube bundle in which the inflow of the heat medium is stopped. | 12-12-2013 |
20130327510 | HEAT EXCHANGER - A heat exchanger is provided with a heat transfer tube bundle housing duct for housing heat transfer tube bundles, openings provided on a sidewall of the heat transfer tube bundle housing duct, for freely inserting and removing the heat transfer tube bundles, and rails provided in a direction perpendicular to an inflowing direction of a flue gas G within the heat transfer tube bundle housing duct, for freely moving the heat transfer tube bundles. Since the heat exchanger can draw out only a specific heat transfer tube bundle, it is possible to reduce a maintenance period, thereby minimizing a regular inspection period. | 12-12-2013 |
20130340976 | HEAT EXCHANGER AND METHOD FOR ESTIMATING REMAINING LIFE OF HEAT EXCHANGER - Dummy tubes are each provided near a gas inlet side and a gas outlet side of a heat recovery unit and near a gas discharge side of a re-heater via an intubation, and a heat medium is circulated in the dummy tube by a branched path which branches from a medium circulation path. The dummy tube is periodically extracted to check the quantity of thickness reduction of the surface thereof. Thus, it is possible to check the quantity of thickness reduction of the surface of the dummy tube, and determine the state of damage or the like of a heat transfer tube. | 12-26-2013 |
