20130156673 | AIR POLLUTION CONTROL SYSTEM AND METHOD - An air pollution control system comprises a SOx removal equipment for reducing sulfur oxides from flue gas from a boiler, a cooler for reducing the sulfur oxides that remain in the flue gas and for decreasing a gas temperature, CO | 06-20-2013 |
20130248121 | SPRAY-DRYING DEVICE FOR DEHYDRATED FILTRATE FROM DESULFURIZATION WASTEWATER, AIR POLLUTION CONTROL SYSTEM AND FLUE GAS TREATMENT METHOD - A spray-drying device includes a spray nozzle that sprays the dehydrated filtrate from the desulfurization wastewater, in a spray-drying device body, an inlet that is provided in the spray-drying device body and introduces flue gas for drying spray liquid, a dry area that is provided in the spray-drying device body and dries the dehydrated filtrate by the flue gas, an outlet that discharged the flue gas contributing to the drying, a plurality of thermometers that are provided in the dry area and measure temperatures of the inside, a determination unit that determines whether or not a spray-drying state of the dehydrated filtrate is satisfactory on the basis of the measurement results of the thermometers, and a control unit that adjusts the flue gas or the dehydrated filtrate when it is determined that the spray-drying is not satisfactory as a result of the determination of the determination unit. | 09-26-2013 |
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 |
20140045131 | SPRAY DRYING APPARATUS FOR DEHYDRATED FILTRATE FROM DESULFURIZATION WASTE WATER, AND AIR POLLUTION CONTROL SYSTEM - A spray drying apparatus includes: a gas inlet provided in a side wall in the vicinity of a top (lid) portion of the spray drying apparatus, for introducing a flue gas for drying a spray of dehydrated filtrate; flow-adjusting plates provided in a body of the spray drying apparatus, for decelerating the introduced flue gas so as to change the flow of the flue gas to a laminar flow; a spray nozzle for spraying the dehydrated filtrate from the desulfurization waste water into the flue gas having been changed to the laminar flow; and a joining unit for joining a bottom portion of the body of the spray drying apparatus to a gas supply line that is a main flue gas duct for the flue gas so as to discharge spray-dried solids to the main flue gas duct. | 02-13-2014 |
20140083629 | SPRAY DRYING APPARATUS OF DEHYDRATION FILTRATE FROM DESULFURIZATION WASTE WATER, AND AIR POLLUTION CONTROL SYSTEM - A spray drying apparatus includes a gas inlet provided on a side wall in the vicinity of a top portion of the spray drying apparatus, for introducing a flue gas for drying a spray liquid of a dehydration filtrate; a rectifying plate provided in a spray drying apparatus main body, for decelerating the introduced flue gas so as to alter the flue gas flow to a laminar flow; a spray nozzle for spraying the dehydration filtrate emitted from the desulfurization waste water into the flue gas altered to the laminar flow; a gas outlet provided in the vicinity of a bottom portion of the spray drying apparatus main body, for discharging the flue gas contributed to drying of the dehydration filtrate; and a discharge hopper provided on the bottom portion side of the spray drying apparatus main body, for discharging an ash as a spray-dried solid. | 03-27-2014 |
