A regenerative furnace without flue gas circulation to the regenerator beds is heated by combusting synthesis gas with an oxidant. The synthesis gas is produced from steam and methane in a first regenerator bed, heated in the previous cycle while a second regenerator bed, cooled in the previous cycle, is heated by passing through it a hot flue gas from a source other than the furnace. Once the first regenerator bed is cooled through the endothermic chemical reaction of the steam and methane, it is heated by hot flue gas, while steam and methane are reacted in the second, now hot, bed thereby cooling it.
