20080295480 | Integrated gasification combined cycle power generation plant - A gasifying agent supply path A from an axial flow compressor | 12-04-2008 |
20100175364 | INTEGRATED COAL GASIFICATION COMBINED CYCLE FACILITY - An integrated coal gasification combined cycle facility is provided that can prevent a reduction in power generation efficiency even when low-grade coal having a relatively-high moisture content is used. Included are: a gasification section that gasifies supplied coal; a gas power generation section that generates power by using gas supplied from the gasification section; a steam power generation section that generates power by using the heat of exhaust gas discharged from the gas power generation section; and a coal drying unit that dries the coal by using exhaust heat discharged from the steam power generation section and that supplies the dried coal to the gasification section. | 07-15-2010 |
20110116979 | COAL GASIFIER - Provided is a coal gasifier enabling a reduction in size of a shift reactor by generating hydrogen-rich gasified coal gas. In a coal gasifier generating gasified coal gas by a gasification reaction proceeding in a furnace fed with a gasifiable raw material, such as coal, and a gasifying agent, at least one of water and steam is fed to the furnace as a material accelerating a hydrogen-generating reaction that proceeds simultaneously with the gasification reaction. | 05-19-2011 |
20110126743 | GASIFICATION FURNACE APPARATUS - Provided is a gasification furnace apparatus equipped with a supply source of low-oxygen-concentration drying gas that does not require fuel. A coal pulverizer that produces pulverized coal by pulverizing coal, an air separator that separates air into oxygen gas and nitrogen gas, and a gasification furnace that produces product gas by introducing thereinto the pulverized coal and the oxygen gas, are included. By receiving a supply of excess nitrogen gas from the air separator, the air diluted with nitrogen is used as a source of low-oxygen-concentration gas for drying the pulverized coal, and an air heater that heats the source of low-oxygen-concentration gas to a temperature at which drying can be performed is provided. | 06-02-2011 |
20110139047 | INTEGRATED COAL GASIFICATION COMBINED CYCLE POWER GENERATION SYSTEM - Provided is an air-blown integrated coal gasification combined cycle power generation system equipped with a carbon-dioxide capturing device, in which the integrated coal gasification combined cycle power generation system eliminates the need for an air separator by obtaining a new carrier source that replaces nitrogen gas serving as a carrier gas for pressurizing and carrying pulverized coal and char. In an integrated coal gasification combined cycle power generation system that employs an air combustion method of using air as an oxidizing agent to generate coal gas in a gasification furnace and that supplies the coal gas to a gas turbine after separating and capturing carbon dioxide from the coal gas in a carbon-dioxide capturing device, a portion of the carbon dioxide separated and captured by the carbon-dioxide capturing device is used as a carrier gas for pulverized coal and char. | 06-16-2011 |
20110308230 | INTEGRATED COAL GASIFICATION COMBINED CYCLE PLANT - Provided is an integrated coal gasification combined cycle apparatus that can operate a coal pulverizer using gas turbine exhaust gas as drying gas even when the concentration of oxygen in the gas turbine exhaust gas to be used as the drying gas is temporarily increased. In the integrated coal gasification combined cycle plant using combustion exhaust gas from a gas turbine as the drying gas for a coal pulverizer and adjusting the temperature of the drying gas by mixing outlet gas from a denitration device installed inside an exhaust gas boiler and outlet gas from the exhaust gas boiler, an auxiliary burner is started when the concentration of oxygen in the drying gas is increased to a predetermined value or more and is installed so as to adjust the concentration of oxygen in the drying gas using the combustion exhaust gas generated thereby. | 12-22-2011 |
20110314814 | HYDROGEN PRODUCTION SYSTEM AND POWER GENERATION SYSTEM - The amount of high-temperature steam supplied from external equipment is reduced. Provided is a hydrogen production system ( | 12-29-2011 |
20120137689 | HYDROGEN PRODUCTION APPARATUS AND POWER GENERATION PLANT - A hydrogen production apparatus ( | 06-07-2012 |
20130247465 | HYDROCARBON FEEDSTOCK GASIFIER - A hydrocarbon feedstock gasifier (gasifier) is provided with: a heat transmission surface disposed within a gasification region of a gasifier configured from a pressure vessel for generating produced gas by partially oxidizing coal which is a hydrocarbon feedstock; a heat exchanger disposed on the path of a circulation line for a circulation medium circulating within the heat transmission surface and for exchanging the heat of the circulation medium; and a circulation pump for circulating the circulation medium. | 09-26-2013 |
