Definitions

  • the invention relates to a heating and cooling machine, in particular Vuilleumier heat pump or Stirting machine, in which a gas-air mixture burns in a combustion chamber and the exhaust gas gives off the thermal energy to a heater head as a housing for the hot piston of the machine, which with forms part of its outer surface part of the combustion chamber.
  • a heating and cooling machine of this type is known from DE 195 16 499 A1 and US 5 214 923.
  • the gas-air mixture is introduced directly into the combustion chamber, ignited and burned.
  • the heat transfer takes place by convection of the exhaust gas on the wall of the combustion chamber and thus directly to the heater head. Therefore, only a corresponding efficiency in energy transmission can be achieved.
  • a burner for a heating and cooling machine in which a gas-air mixture burns in a combustion chamber and the exhaust gas emits the thermal energy to a heater head, which acts as a housing for a hot piston of the heating and cooling machine serves and which forms part of the combustion chamber with part of its outer surface.
  • the heater head is cylindrical and enclosed by a hollow cylindrical pore burner to which the gas-air mixture is fed at the end. The heat transfer to the heater head takes place through Convection.
  • the material of the pore burner contains catalytically active particles that cause an exothermic reaction.
  • the heater head itself has a concave receptacle as a combustion chamber for a pore burner, which encloses the majority of the outside of the pore burner with the exception of the inflow surface for the gas-air mixture and that the heat transfer by means of convection and radiation to the heater head.
  • the machine can be compactly constructed and optimally adapted to the spatial conditions.
  • a large modulation range in performance is achieved.
  • the pore burner is arranged at a distance from the heater head or lies against it over a large area in order to achieve an optimal setting with regard to efficiency, pollutant emissions and modulation range.
  • the pore burner can completely fill the concave receptacle in the heater head.
  • the combustion of the gas-air mixture in the pore burner can be stabilized in that the gas-air mixture can be fed to the pore burner via a porous non-return fuse body, which has the inflow surface of the same covered. A uniform firing process is thereby achieved within the pore burner.
  • non-return safety body is preceded by a distribution chamber, the output cross section of which corresponds to the input cross section of the non-return safety body.
  • the removal of the exhaust gas is ensured in one case in that the combustion chamber in the area of the inflow surface of the pore body and the non-return fuse body is covered by a housing with an exhaust gas outlet or in the other case by the pore burner by means of a housing part with an exhaust gas outlet is covered, which is designed in the area of the inflow surface of the pore burner as a non-return fuse body.
  • At least part of the housing part is designed as a heat exchanger for a liquid flowing through, which can be used as process water.
  • the heater head 20 has a concave receptacle 21 in the end face, into which a pore burner 10 is inserted.
  • the pore burner 10 is cylindrical and can be designed as a wire mesh, porous ceramic body and the like. It has the advantage that a stable combustion process with low pollutant values can be achieved over a large modulation range of the power.
  • the receptacle 21 surrounds at a distance the most important part of the outer surface of the pore burner 10 with the exception of the inflow surface for the gas-air mixture, which is covered by a plate-shaped, porous non-return valve body 11.
  • a non-return fuse body 11 may be preceded by a distribution chamber, the output cross section of which is the input cross section corresponds to the non-return fuse body 11.
  • a fan 12 promotes air L and mixes it with gas G. As a gas-air mixture, this fuel enters the pore burner 10 and burns there after ignition (not shown).
  • a housing part 15 completes the cover of the combustion chamber, which is provided with the exhaust gas outlet AG.
  • the heat transfer takes place from the pore burner 10 to the heater head 20 by means of convection and radiation, the proportion of which is particularly high when a pore burner 10 is used.
  • the pore burner 10 completely fills the concave receptacle 21 in the heater head 20 and bears against it.
  • a pot-like, porous non-return safety body 11 is inserted, via which the gas-air mixture is supplied.
  • the exemplary embodiment according to FIG. 2 does not differ from the exemplary embodiment according to FIG. 1.
  • the configuration can also vary between the two exemplary embodiments and can be adapted in the distance or filled volume of the pore burner 10.
