Definitions

  • the present invention relates to a combustion chamber for a hot gas generator of an asphalt production plant, a hot gas generator comprising the combustion chamber, a plant for the production of asphalt comprising the hot gas generator, a use of the plant for drying and heating granular mineral and/or recycled asphalt material for asphalt production, a method for fastening air baffles in a base body of a combustion chamber for a hot gas generator and a method for connecting air baffles following one another in the longitudinal direction of the combustion chamber in a base body of a combustion chamber for a hot gas generator according to the preambles of the independent claims.
  • drum dryers with rotating drying drums are used, in which a material curtain is formed from the granular material, which is permeated by a hot gas stream.
  • the material to be dried and heated passes through the drying drum in the same direction as the hot gas flow (cocurrent drum dryer) or in the opposite direction to the hot gas flow (countercurrent drum dryer).
  • the hot gas flow is provided by a hot gas generator, which is usually fired with fossil fuels such as natural gas, heating oil or coal dust or, for example, also with wood dust, which has a combustion chamber and a burner includes.
  • the combustion chamber in turn includes a fixed base body lined with air baffles that form the radial boundaries of the combustion chamber of the combustion chamber.
  • secondary air is routed between the inside of the base body and the air baffles, which cools the air baffles and is introduced into the combustion chamber at various points through defined openings in order to obtain a hot air flow that is as homogeneous as possible at a specific temperature at the outlet end of the combustion chamber.
  • the air baffles are held axially displaceably on the inside of the base body with retaining plates welded onto radial webs, and the air baffles that follow one another in the longitudinal direction of the combustion chamber are each welded directly to one another or are firmly connected to one another via welded-on connecting profile pieces.
  • the DE202008012971U1 discloses a combustion chamber for a hot gas generator with the features of the preamble of the first claim.
  • the U.S. 5,363,642 discloses a method for connecting air baffles that follow one another in the longitudinal direction of the combustion chamber in a base body of a combustion chamber.
  • a first aspect of the invention relates to a combustion chamber for a hot gas generator of an asphalt production plant.
  • the combustion chamber comprises a drum-like base body with a burner end and a hot gas outlet end. Viewed in the circumferential direction of the combustion chamber, the base body is lined on its inside with several successive air baffles for secondary air, the outsides of which face the inside of the base body and the insides of which form the boundaries of the combustion chamber of the combustion chamber.
  • the secondary air used is mostly hot gas or process air from associated processes, e.g. raw gas from a black material drum or chimney air.
  • the air baffles can each extend in one piece over the entire length of the combustion chamber, viewed in the longitudinal direction of the combustion chamber, or there can be a plurality of air baffles following one another in the longitudinal direction of the combustion chamber, which is preferred.
  • At least part of the air baffle plates is held in the base body by means of latch-bar arrangements. This is achieved in that fastening tabs protruding radially beyond the inner sides of the air baffles into the combustion chamber are interspersed with fastening bars, which create a form fit in the radial direction pointing towards the center of the combustion chamber between the fastening tabs and the inner sides of the air baffles.
  • the invention makes it possible to remove individual air baffles from the combustion chamber interior without destroying components and then reinstall them, be it to replace them or to install them again, with little expenditure of time, material and work Check and/or clean the secondary air area.
  • Retaining plates are preferably arranged between the fastening bars and the inner sides of the air baffle plates, through which the fastening lugs pass.
  • the use of retaining plates results in the advantage that the surface generating the radial form fit with the inside of the respective air baffle can be designed independently of the fastening bar and can thus be optimized for protection against wear.
  • these holding plates preferably rest without play on the inner sides of the respective air baffle plates, while on their other side they border on the respective fastening bars. In this way, a substantially vibration-free attachment of the air baffles can be achieved.
  • the retaining plates have such a radial distance from these stop surfaces that the air baffles are located between these stop surfaces and can move the holding plates radially by a certain amount of play.
  • This amount of play is preferably at least 3 mm, in particular at least 5 mm. With this amount of play it can be achieved that during manufacture of the combustion chamber the air baffle plates can be easily installed by axially pushing them in from the hot gas outlet end of the combustion chamber. This also makes it possible to prevent or at least significantly reduce stresses in the event of manufacturing inaccuracies and thermal expansion.
  • the fastening tabs are located between opposing delimitations of the air baffle plates running in the longitudinal direction of the combustion chamber Combustion chamber inside, the respective fastening bars and / or retaining plates overlap these limitations to form the radial form fit. In this way, free axial displaceability of the air baffle plates can be ensured in a simple and reliable manner.
  • fastening tabs arranged between the boundaries of the air baffle plates running in the longitudinal direction of the combustion chamber are interspersed with the fastening bars in the circumferential direction of the combustion chamber.
  • the tabs can be made very flat in the circumferential direction of the combustion chamber and the distance between the boundaries of the air baffle plates can be chosen to be correspondingly very small.
  • the base body of the combustion chamber is lined on its inside with a plurality of successive air baffles both in the circumferential direction of the combustion chamber and in the longitudinal direction of the combustion chamber.
  • the air baffles therefore do not extend in one piece over the entire length of the combustion chamber, viewed in the longitudinal direction of the combustion chamber, but rather several air baffles follow one another in the longitudinal direction of the combustion chamber. This has the advantage that the installation/dismantling of the air baffle plates is simplified and only certain areas can be removed in a targeted manner for replacement or control purposes.
  • the air baffles following one another in the longitudinal direction of the combustion chamber are connected to one another so that they expand together during heating and cooling and also contract together again without significant gaps occurring between them.
  • This is advantageously done by means of lug-bar arrangements such that connecting lugs are formed on the opposite delimitations of the successive air baffle plates in the longitudinal direction of the combustion chamber, which project radially into the combustion chamber and enforce a common retaining plate, which creates a form fit in the longitudinal direction of the combustion chamber between the connecting straps.
  • the free ends of the tabs, which emerge from the side of the retaining plate facing the combustion chamber, are penetrated by a connecting bar which secures the retaining plate.
  • the connecting lugs which pass through a common retaining plate, lie on top of one another, as seen in the direction in which the connecting bar is pushed through.
  • the connecting lugs which pass through a common retaining plate, lie next to one another as seen in the direction of the connecting bar.
  • the common retaining plate can be secured with exactly one connecting bar, which passes through each of the connecting straps penetrating the retaining plate, or with several connecting bars, which each pass through each of the connecting straps penetrating the holding plate, or only some of them. Depending on the installation situation, one or the other variant may be more preferable.
  • connecting lugs which pass through a common retaining plate, are next to one another as seen in the direction of the connecting bar, it is provided, for example, that they together form a passage opening for a connecting bar. In this way, the desired connection can also be produced with such arrangements of the connecting straps with a single connecting bar.
  • the connecting tabs are advantageously penetrated by the connecting bars in the longitudinal direction of the combustion chamber or in the circumferential direction of the combustion chamber. Depending on the installation situation, one or the other variant may be more preferable.
  • the fastening bars and/or connecting bars are preferably designed in such a way that they strike at least one of the fastening straps or connecting straps with a stop face in a form-fitting manner in the direction of penetration. In this way, assembly is made easier and a precisely defined installation position can be ensured. In addition, any securing of the bolts is only necessary at one end of the bolts as a result of this configuration.
  • Such a securing of the fastening bolts and/or connecting bolts is advantageously carried out with a material application after the assembly of the bolt exclusively on its surface by welding, in particular by means of one or by means of several welding points, which positively secure the bolt against removal from the intended position.
  • Such a securing method has the advantage over welding with the tabs and/or retaining plates that the material applied to remove the bolt can be simply ground away with a grinding machine and without material removal on other components and the bolt can then be used again.
  • the air baffle plates preferably have a profile running in the longitudinal direction of the combustion chamber, so that on their outsides they form flow channels for the secondary air that extend in the longitudinal direction of the combustion chamber.
  • At least some of the air baffles that follow one another, viewed in the longitudinal direction of the combustion chamber, are designed in such a way, for example by means of a stepped profile, that their facing one another Limitations to the end of the hot air outlet pointing out outlet openings form for secondary air from the respective flow channel extending behind it.
  • the air baffles that follow one another as seen in the longitudinal direction of the combustion chamber, the boundaries of which face one another form the air outlet openings pointing towards the hot air outlet end, are preferably connected to one another by means of latch-bar arrangements in such a way that at the opposite boundaries of the air baffles in the longitudinal direction of the combustion chamber each connection tabs are formed, which protrude into the combustion chamber.
  • These connecting shackles each pass through a common holding plate, which creates a form fit in the longitudinal direction of the combustion chamber between the connecting shackles passing through it and is each secured by means of a connecting bar which passes through the connecting shackles on the side of the holding plate facing the combustion chamber.
  • the connecting lugs which each pass through the common retaining plate, lie next to each other as seen in the direction of penetration of the connecting bar and together form a passage opening for a single common connecting bar which passes through the connecting lugs in the circumferential direction of the combustion chamber. Realizing the connection of the air baffles in this way requires particularly little space in the circumferential direction of the combustion chamber and therefore offers maximum design freedom for the formation of the air outlet openings.
  • At least a part of the combustor longitudinal direction on top of each other following air baffles is profiled in such a way that their mutually facing boundaries adjoin each other essentially steplessly.
  • at least some of these air baffles have air outlet openings pointing toward the combustion chamber for secondary air from a flow channel extending behind them.
  • These air baffles which have air outlet openings pointing towards the combustion chamber, are preferably arranged between the hot gas outlet end and the air outlet openings pointing towards the hot air outlet end, viewed in the longitudinal direction of the combustion chamber. It has been shown that a particularly uniform temperature of the hot gas stream exiting the combustion chamber can be achieved in this way.
  • the air baffles following one another seen in the longitudinal direction of the combustion chamber which are profiled in such a way that their mutually facing boundaries adjoin one another in an essentially stepless manner, are preferably connected to one another by means of latch-bar arrangements.
  • the connection is designed in such a way that connecting lugs are formed in the central areas on the opposite delimitations of the air baffle plates in the longitudinal direction of the combustion chamber, which protrude into the combustion chamber.
  • These connecting lugs each pass through a common retaining plate, which creates a form fit in the longitudinal direction of the combustion chamber between the respective connecting lugs.
  • the retaining plate is secured by means of a connecting bar, which passes through the connecting lugs on the side of the retaining plate facing the combustion chamber.
  • the connecting tabs which each pass through the common retaining plate, are preferably located one above the other as seen in the direction of penetration of the connecting bar and are passed through by a common connecting bar in the longitudinal direction of the combustion chamber.
  • This type of connection of the air baffles that follow one another in the longitudinal direction of the combustion chamber is special easy to manufacture and is preferably realized in the middle of the opposite borders of the same. This results in the advantage that a single tongue-and-bar connection is sufficient for connecting two air baffles that follow one another in the longitudinal direction of the combustion chamber.
  • a second aspect of the invention relates to a hot gas generator for an asphalt production plant, which has a combustion chamber according to the first aspect of the invention and a burner for generating a hot gas flow through the combustion chamber.
  • a third aspect of the invention relates to a plant for the production of asphalt, comprising a hot gas generator according to the second aspect of the invention and a drum dryer, preferably a countercurrent drum dryer, which is or can be charged with hot gas by the hot gas generator.
