A combustion method in which heated flue gas heats a regenerator through which a mixture of fuel and flue gas is then passed to undergo endothermic reactions that produce syngas which is fed into a furnace together with a motive gas stream, wherein fuel is combusted with the motive gas stream to provide heat in alternate cycles.

Enhancement of thermochemical regeneration operation

A pressurized cavity is provided around at least a portion or all of a regenerator, within which gas such as flue gas is maintained at a pressure in excess of the pressure within the regenerator, to protect against leakage of gas through the walls of the regenerator.

Regenerators with pressurized cavity in partition walls

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.

Flue gas recycle method for thermochemical regeneration

Employing furnace combustion gases for both thermochemical regeneration and heating of regenerators to preheat oxidant for the furnace provides synergistic efficiencies and other advantages.

Thermochemical regeneration with oxidant preheating

A thermochemical regenerator system is operated without encountering accumulation of unwanted solids on the interior surfaces of the passages through which flue gas passes.

Reduction of regenerator clogging

Operation of a thermochemical regenerator at a controlled ratio of recycled flue gas to reforming fuel provides formation of fuel species that permit a higher flame temperature upon combustion of the resulting combustible mixture.

Thermochemical regeneration with superadiabatic flame temperature

Efficiency of a thermochemical regeneration combustion system is enhanced by incorporation of gaseous products from pyrolysis of fuel such as biomass.

Efficient use of biomass in regenerative furnace firing

Operation of a thermochemical regenerator to generate soot or to increase the amount of soot generated improves the performance of a furnace with which the thermochemical regenerator is operated.

Thermochemical regeneration with soot formation

A combustion method in which heated flue gas heats a regenerator through which a mixture of fuel and flue gas is then passed to undergo endothermic reactions that produce syngas which is fed into a furnace together with a motive gas stream.

Combustion method for low velocity reactant streams

A glassmelting furnace is provided in which the burners are elevated above the glassmelt surface and are oriented at an angle upwards relative to the glassmelt surface.

Upwardly angled burners in glass furnaces

Disclosed is a combustion method in which heated flue gas heats a regenerator through which a mixture of fuel and flue gas containing NOx is passed to undergo endothermic reactions that produce syngas and destroy NOx.

Low-NOx combustion method

Operation of a thermochemical regenerator combustion system in which fuel is fed with furnace flue gas into the regenerators to reduce the oxygen content and optionally to establish a reducing atmosphere in both cycles in which the regenerators operate.

Thermochemical regeneration with fuel additions

Gaseous combustion products from a glassmelting furnace after being passed through a regenerator are used to heat glassmaking feed material and pyrolyze organic material on the feed material. Gaseous pyrolysis products and the combustion products are combined with reforming fuel and passed through a regenerator heated in a previous cycle to form syngas which is fed into the furnace and combusted.
