Definitions

  • This invention relates to cooling apparatus for a cremator intended to cool a coffin during loading into the cremator and prevent premature ignition thereof.
  • the cremating furnace is normally operated at a high temperature, for example 850° C.
  • a high temperature for example 850° C.
  • such operating temperatures may be governed by environmental considerations and legislation may impose minimum operating temperatures on cremator operators.
  • certain materials will ignite very quickly, for example, the varnish finish on a coffin.
  • the varnish would spontaneously ignite causing flame and smoke to discharge backwardly into the loading room. Such occurrences can be hazardous to the operator and cause a fire risk in the operating room.
  • a preferred aspect of the invention therefore provides cooling apparatus for a cremator comprising means for forming a curtain of water across a cremator's entrance, the means being arranged to operate at least during the period for which a door of the cremator is opened for loading thereof.
  • a curtain of water by way of, for example, a plurality of nozzles such that as a coffin is loaded into the cremator a cooling film of water is formed on the exterior surface.
  • a cooling film of water is formed on the exterior surface.
  • the coffin itself is cooled below the combustion temperature of its varnish or other flammable materials and premature ignition thereof is prevented. Whilst loading is being effected it will be understood that the temperature of the cremator can be maintained at the normal ignition temperature and that ignition of the coffin can take place only when the water spray has been turned off.
  • the water spray is operated automatically by the opening of the door to the cremator such that a curtain of water is formed immediately prior to the insertion of a coffin. Additionally the water spray is automatically stopped on the closing of the door such that the coffin is no longer cooled and ignition can take place normally thereafter.
  • a further advantage of apparatus according to an aspect of the invention is that increased control over the cremators oxygen content is obtained.
  • Environmental emission laws require that a cremator has a minimum oxygen content to sustain combustion, cooling of the cremator reduces the demand for oxygen and hence increases the oxygen present.
  • the apparatus to supply a curtain or spary of water within the cremator whilst it is in use. In this way, smoke emission can be controlled or surpressed when required.
  • the cooling apparatus is provided with override means such that the water spray can be manually or automatically operated via computer when required.
  • the water can be used to cool the cremator furnace either between each loading cycle or at the end of a period of use and when the cremator is desired to be cooled down quickly for an extended period of time or to cool it during the cremation process.
  • a cremator 10 is provided with an entrance 12 and a door 14 disposed so as to be moveable against the entrance 12.
  • the cremator interior 10 is provided with a plurality of gas jets or other similar heating means (not shown) such that objects placed in the interior 16 can be heated to an elevated temperature.
  • a plurality of rollers 18 located outside the furnace and adjacent to the entrance enable large objects to be easily placed within the cremator interior 16. It will be understood that the drawing does not show the full cremator and its furnace and only the entrance or insertion end is shown for simplicity and relevance.
  • the invention therefore provides cooling apparatus 22 in the form of one or more nozzles 24 mounted in the cremator's roof and disposed so as to provide a curtain of water across the entrance 12 to the furnace interior.
  • the nozzles 24 are therefore attached via a pipe 26 or plurality of pipes to a supply of water.
  • Fig. 2 shows the cooling apparatus 22 in more detail, from which it can be seen that the pipe 26 connects to a solenoid valve 28 controlling the flow of water along a pipe 30.
  • the pipe 30 connects to a high pressure pump 32 which draws water from a reservoir tank 34 located relatively thereover.
  • the tank 34 is provided with a non-return valve 36 on its connection to the pump 32, a float valve 38, drain 40 and an overflow pipe 42. Additionally, a re-circulation pump 44 connected to a re-circulation line 46 and return 48 allows for water circulation when necessary.
  • Operation of the cooling apparatus 22 may be either manual or automatic.
  • a control device (not shown) is located, for example, adjacent to the door 14 such that the water spray can be actuated prior to opening of the door 14 and the entrance 12 of the furnace.
  • a control device (not shown) is located, for example, adjacent to the door 14 such that the water spray can be actuated prior to opening of the door 14 and the entrance 12 of the furnace.
  • Such an arrangement however provides a possibility that the door could be opened and a coffin inserted without the water spray being actuated and hence cause premature ignition of the coffin's varnish. Therefore is it preferable to provide automatic control of the cooling apparatus 22 such that the water spray is automatically turned on by the action of opening the door 14. Closing the door 14 will shut the water supply off and hence allow heating of the coffin to take place normally.
  • the cooling apparatus 22 may also be preferable to provide manual override such that the cooling apparatus 22 can be operated in unusual or extreme circumstances.
  • the override may be controlled by way of a computer either by direct operator command or in response to pre-programmed instructions of operating conditons.
