Heat is recovered in the first heat recovery section and / or the sensible heat of the reformed gas passed through the porous heat receiver is recovered in the second heat recovery section, and at least a part of the steam used for the reaction is recovered. A method for producing a reformed gas, characterized in that it is produced.
