摘要： The invention relates to a burner, comprising a primary air tube guiding a fuel mass flow and having a fuel nozzle formed at the burner-opening-side end, and a secondary air tube that coaxially surrounds the primary air tube, and a core air tube preferably coaxially arranged inside the primary air tube, wherein the fuel nozzle forms an ignition device provided with at least one electric resistance wire (16), and which supplies, in the burner, in the region of the fuel ignition location that is forming, the amount of heat energy required for the initiation and the course of the initial pyrolysis and ignition of the fuel conveyed in the primary air tube. The aim of the invention is to create an alternative and improved fuel nozzle. Said aim is achieved in that the fuel nozzle is integrally formed, in that at least one spirally circulating groove is formed in the surface of a secondary air repellent cone facing the secondary air tube, in which groove the at least one resistance wire (16) is spirally wound in at least one resistance wire winding (17) that comprises a plurality of windings.

摘要： In the case of a burner, in particular coal dust burner (12), comprising a fuel pipe (1), a fuel nozzle (2), at least one ignition and/or heat source (3') and a pipe (7, 10) which conducts an oxygen-containing gas and/or recirculated flue gas, wherein the at least one ignition and/or heat source (3') is arranged in the burner interior and is in the form of or comprises an electric heating and/or ignition device (14') by means of which, exclusively by conversion of electrical current into heat energy, the amount of heat energy required within the burner for the initiation and continuation of the initial pyrolysis and ignition is generated and/or provided in the burner interior, in particular in the region of the fuel ignition site that forms, it is the intention to provide a solution which, dispensing with the use of gaseous, liquid or solid additional fuel, permits frequent start-up and shut-down of the burners of a steam generator of a large-scale thermal power plant in an inexpensive manner with regard to fuel consumption, and provides a burner suitable for this purpose. This is achieved in that a stabilizing ring (9) with toothed ring (15) is a constituent part of the electric heating and/or ignition device (14') arranged in the mouth region (13) of the fuel nozzle (2).

摘要： A method for producing electrical energy in a combined energy generation plant (100, 200) which comprises an air treatment unit (10) and a power station unit (20) is proposed. In a first operating mode, air (AIR) is liquefied to form an air liquefaction product (LAIR) and, in a second operating mode, an air liquefaction product (LAIR) is converted into a gaseous or supercritical state, in which said product is introduced into the power station unit (20) and is used for producing electrical energy. In a third operating mode, air (AIR) is condensed in the air treatment unit (10) and used in the power station unit (20) directly for producing electrical energy. It is envisaged that, in the first operating mode, the air (AIR) is cooled to several temperature levels (T1 - T5) by two liquid coolants and the air liquefaction product (LAIR) is correspondingly heated. In addition, in the first operating mode, the air (AIR) is condensed stepwise over several pressure levels (LP, MP, MP1, HP). In addition, in the second operating mode, the air liquefaction product (LAIR) is heated to a further pressure level (HP1) and introduced into the power station unit (20) at this pressure level in gaseous form. Finally, in the third operating mode, the air (AIR) is introduced into the power station unit (20) in separate batches and at different pressure levels (MP1, HP or HP1). A corresponding energy generation plant (100, 200) is likewise the subject matter of the invention.
