Utility
Flue gas recycle method for thermochemical regeneration
3 Jan 23
In a thermochemical regenerator wherein gaseous combustion products that are formed by combustion in a furnace are passed from the furnace into and through a first regenerator, the combustion products are combined with gaseous fuel, and the resulting mixture is passed into and through a second regenerator wherein the mixture undergoes an endothermic reaction to form syngas, the thermochemical regeneration is enhanced by injecting fuel gas into a recycle stream comprising the combustion products from the first regenerator to entrain recycled flue gas that passes out of the first regenerator and to impel the mixture into the other regenerator.
