Patent number: 6837910Abstract: A gasifying apparatus comprises a gasifier, a reformer and a heating device. The gasifier produces a thermal decomposed gas with use of a thermal decomposition reaction of a liquid or solid fuel such as waste or coal, and the heating device heats a low-temperature steam and air so as to be a high-temperature steam and air, which have a temperature equal to or higher than 700 deg. C. The gasifying apparatus has feeding means including fluid passages for feeding the high-temperature steam and air to the gasifier and the reformer. In a thermal decomposition area of the gasifier, the liquid or solid fuel is thermally decomposed to produce the thermal decomposed gas with sensible heat of the high-temperature steam and air and with the heat generated by an exothermic oxidation reaction between the high-temperature air and the liquid or solid fuel. In the reformer, the thermal decomposed gas is reformed in the existence of the high-temperature steam so as to be a high-temperature syngas.Type: GrantFiled: September 19, 2000Date of Patent: January 4, 2005Assignees: Japan Science and Technology Agency, Nippon Furnace Kogyo Kaisha, Ltd., Ishikawajima-Harima Heavy Industries Co., Ltd.Inventors: Kunio Yoshikawa, Tsutomu Yasuda, Masaru Sakai, Toru Ishii

Patent number: 5997596Abstract: A process and apparatus for the production of reformed gases. Natural gas and oxygen are combusted in a first stage to produce carbon dioxide and water. The products of combustion are conveyed to a second stage. Reforming gas and oxygen are injected into the second stage and mixed with the products of combustion to react with the carbon dioxide and water to produce carbon monoxide and hydrogen. The process and apparatus are particularly adapted for use in supplementing the reform gases produced in a Direct Reduced Iron plant wherein iron ore is reduced to iron inside a shaft furnace. The process and apparatus may also be used to provide heated enrichment natural gas for use as a source of carbon in the shaft furnace to provide for carburization of the iron. Additionally, the process and apparatus may be used as a process control device for controlling the temperature of the reformed gases flowing to the shaft furnace.Type: GrantFiled: September 5, 1997Date of Patent: December 7, 1999Assignee: Spectrum Design & Consulting International, Inc.Inventors: Mahendra L.
