MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202617069449 A) filed by Midrex Technologies, Inc. on June 03, 2026, for Electric Gas Heating System And Method In A Direct Reduction Plant Utilizing Hydrogen Or Natural Gas.
Inventors include Michishita, Haruyasu; and Hatakeyama, Taiji.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: Direct reduction systems and methods utilize a direct reduction shaft furnace to reduce the iron oxide with a reduction gas received from a reduction/recycle gas loop. An electric gas heating system disposed in the reduction/recycle gas loop heats up the reduction gas with make-up hydrogen and/or natural gas before introducing to the shaft furnace. The gas heating system includes, in sequence, a primary gas heating unit utilizing a direct or indirect heating mechanism to first heat the reduction gas to a temperature below 600°C or above 700°C to avoid carbon deposition in the gas heating system and a secondary gas heating unit utilizing a direct heating mechanism to second heat the reduction gas to the temperature between 900°C and 1100°C.
