20140069306 | COAL FIRED BOILER PLANT AND COAL DRYING METHOD FOR COAL FIRED BOILER PLANT - Coal is properly dried and the efficiency of a boiler is increased while suppressing any reduction in efficiency of the boiler and the generation of hydrocarbon gas components. Employed are a coal dryer that dries coal, a boiler in which the coal that is dried in the coal dryer is mixed with air for combustion and burned, an air heater that heats the air for combustion that is supplied to the boiler using combustion exhaust gas discharged from the boiler, a precipitator that collects dust included in the combustion exhaust gas, a desulfurization plant that performs a desulfurization process on the combustion exhaust gas, and heat recovery equipment that heats a heating medium using the combustion exhaust gas. The coal dryer dries the coal using the heat energy of the heating medium that has been heated in the heat recovery equipment. | 03-13-2014 |
20140072483 | DESULFURIZATION DEVICE AND PARTICULATE COLLECTION SYSTEM - A desulfurization apparatus includes: a desulfurization section ( | 03-13-2014 |
20140075920 | METHOD AND APPARATUS FOR TREATING EXHAUST GAS - A method for treating exhaust gas is provided, which includes measuring SO3 concentration in the exhaust gas which contains at least SO2 and SO3 by using an SO3 gas analyzer; injecting fine particles into the exhaust gas after the step of measuring; cooling the exhaust gas after the step of injection, by recovering heat from the exhaust gas; collecting fly ash from the cooled exhaust gas; and removing at least SO2 from the exhaust gas after the step of collecting by absorbing the SO2 with an absorbing solution. In addition, an apparatus for treating exhaust gas is provided, which includes an SO3 gas analyzer; a fine particles injector; a heat exchanger; an electrostatic precipitator; an absorption tower; and a fine particle feed controller. | 03-20-2014 |
20140079615 | EXHAUST GAS TREATMENT SYSTEM AND A METHOD OF TREATING EXHAUST GAS - A flue gas treatment system and a flue gas treatment method capable of drastically reducing operating cost and an amount of waste water and capable of controlling an amount of a NOx reducing agent and a mercury oxidation agent to be supplied are provided. The flue gas treatment system sprays an aqueous solution containing ammonium halide into a flue, reduces NOx and oxidizes mercury in a deNOx section, and removes SOx and the mercury in a desulfurization section. The flue gas treatment system adds at least one of ammonium sulfate and ammonium carbonate to waste water which is discharged from the desulfurization section and from which CaSO | 03-20-2014 |
20150139881 | WET TYPE FLUE-GAS DESULFUIZATION APPARATUS AND METHOD FOR ADJUSTING OXIDATION REDUCTION POTENTIAL OF ABSORBENT THEREFOR - A wet type flue-gas desulfurization apparatus includes a desulfurization apparatus main body; a gas introducing unit that is disposed on a side wall of the desulfurization apparatus main body and that introduces a flue gas; an absorbent accumulating unit that accumulates an absorbent which has absorbed the sulfur oxide present in the flue gas; a circulation line that circulates the absorbent from the absorbent circulating unit; a spray pipe that is disposed in the vicinity of the middle portion of the desulfurization apparatus main body and that sprays the absorbent, which is circulated in the circulation line, as a spray liquid from a nozzle; an ORP meter that measures the oxidation reduction potential of the absorbent; and an oxidation resistant pipe group that, in the vicinity of the interface of the absorbent present in the absorbent accumulating unit, cushions a falling liquid falling from an absorber of the absorbent. | 05-21-2015 |
