Abstract: Electrical generator, for the combustion of a liquid and/or gaseous fuel, comprises a tangential injection of a combustive gas in a chamber of combustive-fuel (6) traversed by a rotative flow of combustive that is excited by mobile electrical discharge of high voltage between a central electrode (3) in the form of a rod and another electrode (2) in the form of divergent tuyere. Electrical generator, for the combustion of a liquid and/or gaseous fuel, comprises a tangential injection of a combustive gas in a chamber of combustive-fuel (6) traversed by a rotative flow of combustive that is excited by mobile electrical discharge of high voltage between a central electrode (3) in the form of a rod and another electrode (2) in the form of divergent tuyere (where: the two electrodes are connected to a source of alternative current; the tuyere (2) delimiting an excitation chamber (2a) is situated upstream of the fuel combustion chamber (8); the tyere is placed at the ground potential; and the other electrode (3) is placed either symmetrically or eccentrically to the axis of (2)), and the device is intended initially to: initiate the combustion of the fuel entering separately through a tube (9) located downstream of (2a) and maintain the complete combustion or to facilitate a partial oxidation of the fuel to produce a gaseous mixture composed mainly of hydrogen and carbon monoxide. Independent claims are also included for: (1) a plasma-catalytic process of liquid or gas fuel conversion into a mixture (termed as: synthesis gas or syngas, or reformat) containing hydrogen and carbon monoxide and accompanied by methane and ethylene, comprising: partial oxidation of a fuel with elementary oxygen contained in a combustive gas added to the matter (where the conversion is characterized if the mixture (termed as reactive) of the fuel and combustive gas travels through the device; and the mixture is subjected to a plasma of mobile electric discharge, in order to first initiate a combustion of the fuel and then maintain the partial oxidation of the fuel into gas of synthesis or reformat; and the partial oxidation take place in a device (termed as reactor or reformer) composed of two sections in series for the flow of reactive and products, where the first section (or zone) is the device and the second section (or post-plasma zone) is: located downstream from the first zone, in direct contact with the first zone by means of a tube, and is filled by a catalytic refractory solid (containing nickel that is dispersed, metallic and/or oxidized) whose melting point exceeds 1250[deg]C); and (2) a plasma-catalytic device, to carry out plasma-catalytic conversion, containing two zones in series (for the flow of reactive entering separately by the tube for combustive-fuel and through the tube for fuel (where the reactive is transformed successively into products (syngas or reformat))), where the first zone has a mobile electric discharge and the second zone is filled by a catalytic refractory solid, which is permeable to the flow of reactive and/or products.
