A superadiabatic burner has a flame holder formed from a porous medium, a fuel inlet coupled to the flame holder, a fuel outlet coupled to the flame holder, a preheater comprising an inlet and an outlet coupled to the fuel inlet, and a radiating rod coupled to the porous medium. The porous medium comprises a first porous section and a second porous section. Methods of using the burner allow preheated air or other mixtures to be provided to the fuel inlet as part of a fuel air mixture for the 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.

A burner for implementing a partial oxidation, having at least two channels, more particularly having one central channel and at least one annular channel surrounding the central channel, through each of which a flow of fluid can be passed to implement the partial oxidation, there being an insulating element arranged on an inner face of a wall of at least one channel of the at least two channels at least along part of an axial length of this at least one channel.

A combustion system includes a fuel and oxidant source, a perforated flame holder, and a support structure that supports the perforated flame holder at a selected distance from the fuel and oxidant source. The fuel and oxidant source outputs fuel and oxidant onto the perforated flame holder. The perforated flame holder receives the fuel and oxidant and sustains a combustion reaction of the fuel and oxidant within the perforated flame holder.

An apparatus for combustion of synthetic gases comprises a burner (75), a combustion chamber (62) cooperating with the burner (75) and having an outlet (64) destined to eject exhaust gases, a fluid supply circuit (65) configured for supplying a comburent gas to the burner (75), wherein the fluid supply circuit (65) is at least partially outside the combustion chamber (62) and has one or more channels (66) in contact with an outer surface (62a) of the combustion chamber (62) for exchanging heat with the combustion chamber itself. A plant and a process using the above combustion apparatus are also described.
