Definitions

  • the invention is directed to a method for heating a high-temperature Winkler gasifier during the start-up of the gasifier with the use of at least one burner which serves for heating purposes, wherein the gasifier head is assigned a cyclone with a return conduit for returning the particles separated off in the cyclone into the fluidized bed in the lower region of the gasifier, and to a correspondingly equipped high-temperature Winkler gasifier.
  • the system comprising gasifier/cyclone/return conduit must initially be heated.
  • the fire-resistant masonry is heated to the operating temperature corresponding to the admissible temperature gradient, wherein the stored heat introduced into the masonry serves to bring a fluidized bed material to the temperature required for the ignition process.
  • the gas burners being fitted in the lower region of the gasifier for heating purposes.
  • the gas burners it is necessary for the gas burners to be mounted when the gasifier is in a shut-down state, and to be dismounted again after the completion of the heating process and before the actual start-up of the gasifier, wherein the required gasifier connectors must be closed before start-up.
  • a particular disadvantage of this procedure is that the gasifier, once fully heated, cannot be immediately ignited. Therefore, during the dismounting of the burners, which may take, for example, at least one hour, considerable heat losses are incurred. Furthermore, the personnel involved in the dismounting process are exposed to a corresponding level of heat, such that protective equipment must be provided for the personnel.
  • gasifier diameters of 3.5 to 4 m, with a gasifier height of approximately 30 m, are necessary.
  • a gasifier of said type would require at least four heating burners; these theoretically required four heating burners would have to be fitted in the cone of the gasifier. Such a requirement however cannot be met in practice.
  • EP 0 500 517 A1 describes a method for setting in operation a plant for the production of raw iron, wherein, in said method, it is likewise the case that parts of the plant are preheated.
  • HMW Winkler gasifier
  • FIG. 1 is a schematic sectional illustration of a high-temperature Winkler gasifier according to one embodiment of the invention.
  • the burner is operated stoichiometrically or substoichiometrically.
  • a further refinement consists in that, during substoichiometric operation of the burner, combustion air required in the lower region of the gasifier may be additionally injected through different nozzle planes.
  • This method implementation described herein makes use of the fact that various nozzle planes are provided in gasifiers in any case, which nozzle planes perform different functions during the normal operation of the gasifier and, in this case, can be used for the introduction of required combustion air.
  • a further refinement of the invention consists in that a flap may be operated in temperature-regulated fashion in the feed conduit from the gasifier to the separation cyclone. That is to say in particular that, during the starting process, the feed conduit to the separation cyclone can be closed in order to make it possible to realize a correspondingly reversed flow.
  • the one (or more) burner provided in the head of the gasifier is (or are) retracted into a region of relatively low particle concentration.
  • the burners are supplied with coolant for preventing the formation of particle melt phases, either by virtue of the coolant being conducted directly through the burner head, or indirect cooling being performed.
  • the invention also provides a high-temperature Winkler gasifier having a cyclone or centrifugal separator which is assigned to the gasifier head and having a solids return conduit from the cyclone into the lower region of the gasifier. Additionally, in the high-temperature Winkler gasifier head there may be at least one burner which acts into the interior of the gasifier.
  • the cyclone it is expedient for the cyclone to be functionally separated from the gasifier head during start-up.
  • the invention provides that a shut-off or throttle flap is provided in the connecting conduit between gasifier head and cyclone.
  • the burner for the purposes of positioning the burner into regions of relatively low particle concentrations during gasifier operation, the burner (or burners) is (or are) axially movable. It may also be expedient here for coolant to be conducted through the burner for the purposes of preventing the formation of particle melt phases.
  • the invention is not restricted to a particular fuel type.
  • the one or more burners required for the start-up process may be operable with gaseous, liquid or solid fuels, for example with natural gas, or oil or with corresponding carbonaceous powdered material, to name but a few examples.
  • the high-temperature gasifier which is denoted generally by 1 , is illustrated in section and in simplified form.
  • the gasifier body composed of fire-resistant masonry and denoted by 2 has, in the lower conical region 2 a, the means required for the formation of the fluidized bed.
  • a cyclone 3 which, during operation, is provided above a feed conduit 5 which can be controlled by way of a closure flap 4 , wherein the solids that are separated off are supplied via a return conduit 6 back to the lower fluidized bed in the region 2 a of the gasifier.
  • the high-temperature Winkler gasifier is equipped with at least one heating burner 7 in the head denoted by 2 b, wherein said burner 7 can, by way of corresponding means which are not illustrated in any more detail and as per the double arrow 8 , be moved into the gasifier chamber and, during normal operation, retracted out of said gasifier chamber to such an extent that the burner nozzle is not exposed to fouling or additives.
  • the hot combustion products are conducted through the reactor as per the arrows 9 . After the required start temperature is reached, the gas flow runs substantially in the opposite direction, which is the case when starting takes place and the high-temperature flap 4 is opened.
  • air inlet nozzles are provided in the conical region 2 a and in the transition region of the fluidized bed; said nozzles are denoted by 10 .
  • the arrow 11 indicates the supply of fuel
  • the arrow 12 indicates the supply of air.
