Definitions

  • the invention relates to a device for heating a thermo-technical device, in particular a boiler, with solid, pourable fuel, in particular wood pellets, with a burner containing a arranged above an ashtray, acted upon by the fuel and combustion air combustion chamber containing an upward facing Flammaustrittsö réelle has and a bottom-side Entsorgungsluke, which is associated with a movable, provided with openings for primary air closure member, in the ashtray emptied.
  • the disposal hatch associated closure member is formed as a double-walled, a cavity-containing plate, the upper wall is formed as the passage openings for the primary air containing grate plate.
  • Such a device is off EP 0 945 676 A2 known.
  • the closure member is formed as a solid plate, which is provided with through openings for the primary air, which is sucked in here via the ash space. This results in a cooling, coming into contact with the closure member air flow only in the region of the passage openings. There is therefore a risk that the closure member forming massive plate is thermally stressed so much that the life suffers. The consequence of this is a higher maintenance and upkeep. In addition, it may happen that the said plate warps due to their thermal stress, which may affect the mobility.
  • the known arrangement thus proves to be not reliable and reliable enough.
  • This object is achieved in that the distanced from the upper wall bottom wall is formed as an open, the ashtray opposite the combustion chamber occlusive closure plate, and that formed between the grate plate and the closure plate cavity than with a through a partition wall of the adjacent combustion chamber separate, communicating with air pressure chamber communicating air duct is formed, from which the passage openings for the primary air depart and which communicates with a leading to a secondary air opening flow channel.
  • the combustion chamber facing the grate plate is thereby advantageously not only in the region of their passage openings for the primary air, but rinsed on its entire bottom of the passing air and reliably cooled thereof. This ensures that the temperature of the grate plate can be kept within a permissible range even with a high thermal load, which has an advantageous effect on the prevention of wear and the achievement of a long service life.
  • the reliable cooling of the grate plate and an undesirable heat distortion effectively prevented, which has an advantageous effect on the reliability.
  • the air flowing through the cavity absorbs heat, which advantageously results in a preheating of the air flowing to an associated secondary air outlet, which has an advantageous effect on the achievement of good afterburning and thus good economic efficiency.
  • Another advantage of the measures according to the invention is the fact that here an overpressure air supply is possible and an air duct over the ashtray is unnecessary, whereby false air can be largely suppressed.
  • the plate forming the closure member may expediently be designed as a slide displaceably mounted in the region of its side edges. Due to the good cooling a smooth arrangement is guaranteed. The slider can therefore be moved with relatively little force substantially noiseless. During the reciprocating movement of the slide this can be easily stripped off. The slide is therefore assigned a stationary stripping appropriate expediently.
  • the burner housing is designed to be double-walled, at least in the disposal hatch, lower area, wherein the clear distance corresponds to each of the walls provided for forming the Entsorgungsluke window thickness of the closure member forming slide.
  • a further advantageous measure may consist in that the burner housing has a front double-walled region adjoining the lower double-walled region, the interior of which is adjacent to that in the region of the flame outlet opening provided secondary air opening leading flow channel forms.
  • the secondary air duct is integrated into the housing structure in an advantageous manner, which results in a simple construction. At the same time a reliable cooling of the front wall portion of the burner housing is achieved in this case.
  • the burner housing can also be double-walled in its upper region, wherein the interior of this double-walled region communicates with the pressure chamber and leads to a further secondary air opening provided in the region of the flame outlet opening. This results in the upper wall portion of the burner housing reliable cooling.
  • the upper, double-walled region can be penetrated by a feed shaft for the fuel, which is provided with air inlet openings in the region of the intermediate space of the double-walled region.
  • the effluent via these air inlet openings air advantageously forms a barrier air against high-rising heat and dust particles, which increases the reliability.
  • the burner housing is formed as a box-shaped steel component, which is provided with an outer mounting flange and hereby attachable to an associated mounting flange of the heat engineering device.
  • the use of steel provides high strength and results in a self-supporting arrangement which can be attached to any suitable mounting flange, providing high versatility and easy interchangeability.

  • actuable cleaning slide 6 are arranged by means of a pivot lever.
  • the burner 7 In the furnace chamber 3 projects into a burner 7, which is flanged to an associated insertion opening mounting flange 8 of the boiler 1.
  • the burner 7 has a housing 9 made of interconnected steel plates, which is provided with an outer, engageable on the mounting flange 8 retaining flange 10.
  • the boiler 1 may be provided with a plurality of insertion openings associated with the furnace chamber 3. In the example shown are two provided mutually opposite insertion openings, so that the burner 7 is selectively attachable to different sides of the boiler 1.

  • the back and forth movable slide 22 is associated with a stationary stripping device 56, which is the top clears the slide 22, if this is moved under it.
  • the lower end of the partition wall 16, which here forms the rear edge of the window-shaped recess 40 of the upper wall 39 of the housing-side bottom portion acts as the slide 22 associated, stationary scraper.
  • the slide 22 In the FIG. 2 underlying operating position, in which the disposal hatch 21 is closed, the slide 22 is located with its front end on a housing-side front wall. The rear region of the slide 22 projects slightly into the pressure chamber 18, which receives the slide 22 in the retracted state and accordingly has a clear width corresponding to at least the sliding distance in the direction of the slider movement.
