Definitions

  • the invention relates to devices or methods for the cremation of organic bodies, in particular cremation ovens such as these come to the cremation of corpses used.
  • a cremation furnace with Nachverbrennungskanälen is known, which is provided with built-in furnace walls electric heaters.
  • an oven with a main combustion chamber formed in the furnace vault and an afterburning chamber is known, wherein the electrical heating elements are arranged in heating channels provided for this purpose in the supporting structure of the furnace vault.
  • the EP 1 002 994 A1 a device for cremation with a cremation chamber is known in which the cremation chamber is heated by means of an electrically or natural gas-powered heater from the outside and where fresh gas as oxygen in a high concentration in the cremation chamber and afterburning is supplied separately.
  • the cremation chamber is preheated before charging.
  • Another disadvantage is the increased heat loss during the often long-lasting heating phase, since the hottest point is located inside the heat-storing lining and not on its process chamber side surface. It is also undesirable in the prior art that heated in the lining heating elements heat up by the process heat and thereby reach temperatures which adversely affect the service life. Heating elements are wear parts. An exchange of defective heating elements requires a cooling of the furnace, which in turn results in a break of several days. Heating elements can be exposed by progressive erosion of the furnace inner wall. Then there is an increased risk to the operating personnel by electric shock. The relatively high electrical conductivity of the chamotte does not allow personal protection by means of residual current circuit breakers. In order to insert the heating elements in the chamotte expensive expensive molded bricks in refractory design.
  • the invention is therefore based on the object to overcome known from the prior art disadvantages and to provide a device or a method available that allows the cremation of organic bodies safely, completely, environmentally friendly and economical.
  • the object is solved by the specified independent claims.

  • embers fall through a grating that limits their size, in an ash channel or Aschenausbrenn Scheme, where these are fully mineralized under controlled addition of, if necessary, also heated fresh air (ash plate air). Alternatively - if there is no rust - the embers remain on the hotplate of the main combustion chamber.
  • the resulting smoldering gases flow into the second section or zone, also known as the afterburner chamber of the combustion chamber, where they are completely burned with further air supply.
  • the exhaust gases leave the device. Combustion is typically batched and completed when a batch is completely cremated.
  • the device Prior to each charge of a batch, at least prior to a first batch or after service interruptions, the device must be heated to the correct operating parameters.
