Zusammenfassung:The invention refers to the power engineering and may be used in the thermal power equipment.Process for fuel gas burning comprises the fuel gas and fuel blasting air preheating, mixing and ignition thereof and before preheating the fuel blasting air is saturated with oxygen by separation of nitrogen therefrom, before mixing the air saturated with oxygen and fuel gas is ionized with opposite polarity, mixing and ignition is realized by agglomeration of the saturated air and fuel gas ionized particles in the constant electrical field.The installation for fuel gas burning contains a burner with mixing chamber coupled with the furnace embrasure and chambers for fuel blasting air and fuel gas feeding, coupled accordingly to the outlets of preregenerative heaters of fuel blasting air and fuel gas, situated into the burned gas channel of the furnace, and the preheaters inlets are coupled with the high pressure compressors. Into each feed chamber of the burner it is disposed a system of corona electrodes and into the mixing chamber - a system of electrodes for storing the gas ionizing particles, the latter being connected to the high voltage source. The inlets of the two separators containing porous granules strata for nitrogen adsorption are coupled by control valves with a compressor, connected to a nitrogen reservoir. Invenţia se referă la ramura energeticii şi poate fi utilizată în utilaje termoenergetice.Procedeul de ardere a gazelor combustibile include preîncălzirea gazelor combustibile şi a aerului de combustie, amestecarea şi aprinderea lor, iar înainte de încălzire aerul de combustie se îmbogăţeşte cu oxigen prin separarea din el a azotului, înainte de amestecare aerul îmbogăţit cu oxigen şi gazele combustibile se ionizează cu polarităţi opuse, iar amestecarea şi aprinderea se efectuează prin aglomerarea particulelor ionizate de aer îmbogăţit şi de gaze combustibile într-un câmp electric constant.Instalaţia de ardere a gazelor combustibile conţine un arzător cu cameră de amestecare unită cu ambrazura focarului, şi camere de admisie a aerului de combustie şi a gazelor combustibile cuplate, respectiv, la ieşirile preîncălzitoarelor regenerative de aer de combustie şi de gaze combustibile, care sunt amplasate în canalul de gaze arse al focarului, iar la intrările preîncălzitoarelor sunt cuplate compresoare de înaltă presiune. În fiecare cameră de admisie a arzătorului este amplasat câte un sistem de electrozi cu descărcare corona, iar în camera de amesteca
