Definitions

  • the invention relates to a burner for the combustion of particulate, in particular dust-like, carbon-containing fuel, preferably coal or biomass, comprising a fuel or primary air pipe carrying a fuel mass flow with a fuel nozzle formed at its end of the burner opening, which has a stabilizing ring with teeth pointing radially inwards of a ring gear and on the outside has a conical radially outwardly widening jacket air or secondary air deflection cone, and comprises a jacket air or secondary air pipe coaxially surrounding the fuel or primary air pipe and preferably a core air pipe arranged coaxially within the fuel or primary air pipe, the fuel nozzle having at least one Electric heating or resistance wire heating and / or ignition device that forms within the burner for the emergence and the course of the initial pyrolysis and ignition of the fuel conveyed in the fuel or primary air pipe provides the required amount of thermal energy in the region of the fuel ignition location that is formed.
  • the burner comprises a fuel or primary air pipe, which has a fuel nozzle at its end on the burner mouth, which is formed in one piece and has a toothed ring with teeth pointing radially inwards and, on the outside, a conical radially outwardly widening jacket air or secondary air deflection cone.
  • the fuel or primary air pipe is coaxially surrounded by a jacket air or secondary air pipe, which in turn is coaxially surrounded by a tertiary air pipe.
  • a core air tube equipped with an ignition lance is arranged coaxially to the center of the fuel or primary air tube. Acting at the fuel nozzle it is a component which is produced in one piece, for example by centrifugal casting, and which forms the mouth cross section of the fuel or primary air pipe, also called the dust pipe in the case of combustion of coal dust.
  • the stabilizing ring has in particular the function of detecting the fuel conveyed in the fuel or primary air pipe, in particular coal dust, of decelerating its flow rate and of redirecting the fuel mass flow.
  • the definition of the location and the time of the ignition are of crucial importance, since only in this way can the combustion conditions, in particular the stoichiometry, be influenced. This does not allow an indefinite ignition of the fuel in the combustion chamber, since the fuel-air ratio can only be influenced to a limited extent here.
  • Such burners are also from the DE 42 17 879 A1 , the DE 43 25 643 A1 and the DE 195 27 083 A1 known.
  • particulate, carbon-containing fuel-fired power plants which result from the increased feeding of regenerative electrical energy into the power grid. Since the feeding of electrical energy from renewable energy sources into the power grid does not take place evenly, but depends on the availability of sun or wind, conventional, fossil-fired power plants higher demands on load flexibility.
  • particulate carbonaceous fuel such as coal or biomass boilers in particular dust-like fuel with the aid of suitable for this purpose is, in particular NO x fed-poor burners of the kind described above, together with the necessary quantity of combustion air to the combustion chamber.
  • the burners or burner groups are assigned to a number of grinding plants or mills.
  • the steam generator output currently called up is changed by changing the mill or burner output and by switching on or off individual grinding plants and the burners assigned to them. This means that the steam generator output is usually regulated based on the number of burners or burner groups in operation. This means that if the load changes frequently, the burner must be started and stopped accordingly.
  • the ignition generally consists of ignition lances or similar burners, which are arranged in the burner, and with which by combustion of gaseous or liquid auxiliary fuel, such as natural gas or heating oil, for ignition of the burner necessary pilot flame to be burned fuel is generated.
  • gaseous or liquid auxiliary fuel such as natural gas or heating oil
  • the duration results, among other things, from the time required for the preparation of the transportable fuel / fuel dust and the actual transport process to the burner (s). With a frequent load change and thus frequent start-up and shutdown processes of individual mills or grinding plants, this leads to a considerable increase in the costs and expenses for the pilot fuels such as heating oil or gas required when starting a burner, which has a negative impact on the economy of conventional power generation.
  • the invention is therefore based on the object of providing an alternative or improved solution which makes it possible to use a fuel nozzle of a burner equipped with a jacket air or secondary air repellency cone and a stabilizing ring with ring gear as an electrical heating and / or ignition device for the ignition of in the burner trained fuel.
  • the object is achieved according to the invention in that the fuel nozzle is formed in one piece and, in addition to the stabilizing ring and the jacket air or secondary air deflection cone, comprises a fuel or primary air pipe section and in that surface of the jacket air facing the jacket air or secondary air pipe - or secondary air repellency cone is formed at least one spiral groove, in which the at least one heating or resistance wire is spirally wound in at least one heating or resistance wire winding comprising a plurality of turns.
  • an electrical heating or resistance wire is integrated to one for the initial ignition of the burner, that is in the fuel or primary air tube supported fuel mass flow suitable location in the fuel nozzle of a designed for low NOx combustion burner, without adversely changing the mode of operation of the fuel nozzle for continuous operation even after the fuel has been ignited. Since the heating or resistance wire is wound onto the outside surface of the fuel nozzle, in particular the jacket air or secondary air repellency cone, in one or more grooves, the configuration of the fuel nozzle with its functions as part of the fuel or primary air pipe remains as a secondary air repelling groove (jacket air - or secondary air deflection cone) and received as a stabilizing ring.
  • Shaping of the fuel required by the introduction of the heating or resistance wire in or on the material of the fuel nozzle, while maintaining the x low-carbon for NO combustion can be advantageously a generally electrically heated fuel form, the simple construction and by mechanically Machining the surface of the fuel nozzle is simple and inexpensive to manufacture. Since a fuel nozzle is usually exposed to a high thermal load from the combustion chamber and abrasive wear from the fuel mass flow, it is usually made from a high-alloy steel. The surface of the fuel nozzle made from such steel can be machined well with a technically and economically justifiable effort.
  • the heating or resistance wire is not exposed to the fuel nozzle in the configuration of the fuel nozzle according to the invention, since it is arranged on the outer surface of the fuel nozzle. With this outer surface, it can protrude into the flow area of the jacket air or secondary air tube which promotes jacket air or secondary air and in which no abrasive media or only a small number of abrasive particles are conveyed.
  • the outer surface of the spiral heating or resistance wire winding can be covered with an appropriate insulating material.
  • the heating or resistance wire is according to the invention in the area of the most suitable place for the initial ignition, namely in the immediate vicinity of the stabilization ring of the fuel nozzle, so that the area formed in the fuel or primary air pipe in front of the stabilization ring reaches a possible high temperature with the lowest possible electrical heat absorption and thus the lowest possible electrical energy consumption of the resistance wire.
  • grooves or groove-shaped depressions are incorporated in the oblique, conically widening surface of the jacket air or secondary air repellency cone advantageously creates the possibility of a heating or resistance wire with good heat-transferring connection to the material body of the jacket air on this oblique surface - or secondary air deflection cone and at the same time to achieve a good fixation of the heating or resistance wire on the inclined surface.
  • one or more circumferential grooves are formed over the entire length of the jacket air or secondary air deflection cone on its surface facing the jacket air or secondary air pipe, which are aligned spirally and parallel to one another and adjoining one another over the course of the winding and with a diameter of the width and depth of the at least one heating or resistance wire are formed and into which the at least one heating or resistance wire is spirally wound in the heating or resistance wire winding comprising several turns, which the invention provides in one embodiment.
  • the width and depth of the groove corresponds at least approximately to the diameter of the heating or resistance wire, a particularly deep embedding of the heating or resistance wire in the base material and the material body of the jacket air or secondary air repellency cone is ensured and thus a particularly good heat transfer from the Heating or resistance wire reached to the adjacent material areas.
  • the heating or resistance wire winding has a plurality of spirally wound heating or resistance wires, which also distinguishes the invention.
  • a particularly good fixation of the at least one heating or resistance wire or the plurality of heating or resistance wires in the groove or in the grooves can be achieved in that these are connected to the base material or the body material of the fuel nozzle by brazing, this measure It also enables the heat transfer surface to be made more uniform, since areas where the respective heating or resistance wire does not lie directly on the base material or body material are filled by the molten hard solder initially, thereby creating a heat transfer bridge.
  • the invention is therefore characterized in a further embodiment in that the at least one heating or resistance wire or the plurality of heating or resistance wires is / are integrally connected to the material of the jacket air or secondary air repellency cone and the fuel nozzle by means of a molten hard braze.
  • the heating or resistance wire winding on its Jacket air or secondary air pipe facing surface is covered with a heat insulating material.
  • the invention provides that A circumferential stabilization ring groove is formed in the inside of the fuel nozzle facing away from the casing air or secondary air deflection cone in the immediate foot region of the toothed ring of the stabilization ring facing the casing air or secondary air deflection cone. Because a circumferential stabilizing ring groove is formed in the foot region of the ring gear of the stabilizing ring, more fuel is trapped here and the fuel mass flow is stopped more intensely, so that there is more time for heat transfer and ignition compared to the prior art.
  • the invention also provides that the depth of the stabilizing ring groove is at least 5% of the width of the stabilizing ring 5 or the toothed ring 6.
