Furnace operation includes consecutive cycles of a heating step, a stopping step and a restarting step. The fuel and/or the oxidizing agent is preheated upstream of the furnace by indirect exchange with the discharged fumes through a medium passing through a chamber. A first wall separates the fumes from the medium in the chamber. The fuel and/or oxidizing agent is separated from the medium in the chamber by second wall. During restarting, the medium's flow rate Dm is regulated to limit the heating rate of the first wall until it reaches the operational temperature at an end thereof.

Embodiments of the present invention include high-temperature staged recirculating burners and radiant tube burner assemblies that provide high efficiency, low NOx and CO emissions, and uniform temperature characteristics. One such staged recirculating burner includes a combustion tube having inside and outside helical fins forming opposing spiral pathways for combustion gases and products of combustion, a combustion nozzle coupled to the combustion tube, a gas tube running axially into the combustion tube, and a staging gas nozzle coupled to the gas tube, where the staging gas nozzle includes radial exit holes into the combustion tube and an axial gas staging tube extending into the combustion nozzle to stage combustion.

The present disclosure seeks to provide a method to design a metallic burner component for use in industrial processes such as cracking, reforming and steam generation for which the burner component is exposed to high furnace temperatures. The burner component comprises a series of cooling channels and internal baffling to direct the flow of one or more fuel and oxidant over the portions of the burner exposed to the high furnace temperatures. The present disclosure also provides the resulting burner.

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.

Rotor systems are driven by jet engines arranged at the tip of a rotor that includes a structure that turns on a rotational axis. A jet stream generated by a jet engine produces a thrust force orthogonal to a rotor radius to motivate rotation. Methods presented include those which take advantage of the intrinsic centrifugal forces present in the rotor to convey gaseous fuel to the engine. Liquefied fuel from a source reservoir is evaporated into a gaseous state and made subject to centrifugal force causing it to move radially outward to a detonation type jet engine. These methods further include special process for mixing fuel with oxidizer and treating fuel or/and fuel mixtures to improve their detonation capacity.
