Flameless combustion burner for an endothermic reaction process
The present invention relates to a combustion heater (100) for providing controlled heat (H) to an endothermic reaction process. The combustion heater comprises an integrated burner (20) to yield a hot burner exhaust gas (35) flow from burning a first fuel. The burner exhaust gas mixed with oxidant flows to a flue gas outlet along a flue gas flow path (FGP). Provided to the combustion chamber at a position outside a direct reach of flames from the burner is a secondary fuel conduit (30) with a plurality of nozzles (31) from which a second fuel (32) is transferred into a flow along the said flue gas flow path (FGP). The resulting combustion of the second fuel can be used to provide controlled heat to the to endothermic reaction operated in a reaction conduit (40) that is in thermal heat exchange with the combustion chamber.

Industrial furnace
PendingEP4675171A4Liquid fuel feeder/distributionCombustion using multiple fuels
OBJECT To provide an industrial furnace that burns ammonia efficiently while decreasing nitrogen oxides. MEANS OF REALIZING THE OBJECT An industrial furnace 1 burns ammonia using flame F, emitted by a burner 10. Ammonia is supplied to the burner 10 alongside of combustion air and fuel gas. Injection nozzles 21, 22, 23, 24 for ammonia each have a shape of a tube. The injection nozzles 21, 22, 23, 24 for ammonia are provided on a wall surface of a furnace body 2 and pierce the wall surface. The injection nozzles 21, 22, 23, 24 for ammonia each have a top end that protrudes toward the interior of the furnace body 2 from the wall surface. The injection nozzles 21, 22, 23, 24 for ammonia are used to inject ammonia exclusively. In addition, the injection nozzles 21, 22, 23, 24 for ammonia are entirely formed from a catalyst C that decomposes ammonia into hydrogen and nitrogen.

Dual-fuel burner and method of operation
The invention relates to particular burners, and e.g. to a burner comprising a central main fuel lance, a pilot fuel conduit, a main oxidant conduit, an auxiliary oxidant conduit, and optionally a secondary fuel conduit, which are arranged in a particular and advantageous way to surround each other at least in their downstream sections. The invention further relates to furnaces including the burners and methods of operating the burners. Among others, the burners of the present invention allow a particularly advantageous way of including a pilot burner as an integral part of the main burner to ignite liquid fuel flame in a cold furnace. If required, the pilot flame can assist in extending the flammability limit or operating range of the liquid fuel burner.

Fuel-air mixing and flame stabilization device for a low emission burner with internal flue gas recirculation
A flame stabilization apparatus with fuel injection upstream of a torpedo, includes a flame stabilization plate that incorporates spokes that stabilize a flame over a range of operations of a burner. The spokes surround a fuel plenum with respect to the burner. A first group of fuel ports can be located in a fuel tube upstream of the torpedo and a second group of fuel ports can be located in the flame stabilization plate. A discharge cone includes a discharge zone for the burner, wherein the flame with respect to the flue gas is stabilized at an end of the burner in the discharge zone.

Heater with remote combustion air addition
A heater includes a radiant section with a bottom wall and a side wall. A burner is provided on the bottom wall and a primary fuel stream and a primary combustion air stream are provided through the burner to support a primary combustion reaction local to the burner. The primary combustion air stream may be less than the air needed to burn all of the primary fuel stream, resulting in the primary combustion reaction being sub-stochiometric and reducing NOx formation. A remote air pipe injects remote air into the radiant section distal to the burner, and in some cases, spaced from the burner by at least two meters. The remote air addition supports a lean secondary combustion reaction that further minimizes NOx emissions concentration. The heater is suitable for use with high H2 fuel or preheated air, or both, to lower CO2 emissions while meeting NOx emission targets.
