  • Patent number: 6397764
    Abstract: An animal carcass incinerator designed to subject the entire external surface of the biomass material simultaneously to flame. The flame front burns inward toward the core of the material, greatly accelerating the burning process. Complete flame coverage of the biomass material is achieved by carefully shaping the internal surfaces of the incinerator. Burning gases are injected into a lower flame chamber. This lower flame chamber is bounded on its upper side by a grate, and on its remaining sides by the walls of the incinerator. Above the grate is a biomass chamber, where the animal carcasses or similar waste are deposited for incineration. The incinerator walls are lined with refractory insulating materials which incorporate a series of vertical flame channels. Likewise, the grate incorporates a series of vertical open channels. These channels are separated by raised ribs, which prevent the biomass materials from closing off the channels.

The liner is seamless for collection of cremains upon its top surface, which may exhibit a shallow central depression. The liner may include guide structures formed upon its top surface, which are interoperative with complementary structures formed on cleaning tools, particularly with wheels on powered breaking/vacuuming cleaning tools, for positionally guiding such cleaning tools along the length of the liner. By such guidance cremains may be thoroughly cleaned from the entire floor area of the crematory chamber even while the chamber is still at an elevated temperature following a cremation. Alternatively, the floor liner may be extracted from the crematory chamber, and cremains may be thoroughly cleaned from its upper surface.

  • Patent number: 4685403
    Abstract: An auxiliary incinerator apparatus for a crematory includes a main incinerator having primary and secondary chambers formed with a plurality of refractory walls and a main door into the primary chamber. The main incinerator has an outer framework with wall attached thereto and spaced from the refractory walls. The refractory passageway extends from the primary chamber refractory wall to the outer wall. An auxiliary incinerator is attached to the side of the main incinerator outer wall and framework, adjacent to the opening from the refractory passageway through the wall. The auxiliary incinerator has an incineration chamber formed therein with a top opening thereinto. An auxiliary door simultaneously opens and closes over the opening from the refractory passageway through the outer wall and over the opening into the auxiliary incinerator, so that partially incinerated materials can be moved from the main incinerator to the auxiliary incinerator for further combustion.

  • Patent number: 4603644
    Abstract: The cremator disclosed is of the kind in which reduction burning takes place in a coffin chamber, followed by oxidation burning in an afterburner chamber. It is also of the kind in which partly cremated embers can be moved to an ember-reducing location to make room for another coffin to be admitted to the coffin chamber. The disclosure shows the ash removal port in the side of the cremator, which allows the afterburner chamber to occupy space behind and underneath the coffin chamber; an arrangement which makes for a very compact, fuel efficient, easy-to-construct unit. The hearth includes an ash-trough for ember reduction. The hearth can be thin because it is supported on the central wall that divides the ducts of the afterburner chamber, which makes for good heat transfer, and quick warm-up.

  • Patent number: 4473012
    Abstract: This invention provides a system for breaking and removing cremated remains from a crematory furnace. The system includes means for breaking cremated remains into fragments for transmission through a vacuum line into a grinder which reduces the fragments into fine particles. A filter collects fine particles output from the vacuum line; and after completion of the grinding process, the output of the grinder and the particles collected in the filter are collected in a receptacle for removal from the system.

  • Patent number: 4401038
    Abstract: A cremator having a pivotable hearth and a secondary moveable hearth displaceable along a primary chamber and a secondary chamber is disclosed. The pivotable hearth is rotated by means of an exterior hydraulic cylinder coupled to a pivotable hearth. The primary and secondary chamber are separated by an interior wall having a lower portion in close contact with the secondary moveable hearth. Means are provided for moving the secondary hearth from an initial position to sequentially a downward position, a sideways position, an upward position and a final sideways position corresponding to the initial position.

  • Patent number: 4321878
    Abstract: A cremator is provided with a primary cremation chamber and a secondary cremation chamber adjacent to and in communication with the first chamber. A method of cremating bodies utilizing the apparatus disclosed wherein a body is eighty percent consumed in the primary chamber and is then moved to the secondary chamber wherein it is consumed together with the by-products of the cremation of a second body in the primary chamber. Cremation in the secondary chamber utilizes the heat of combustion of the second body in the primary chamber to increase the efficiency of the system.

  • Patent number: 4257335
    Abstract: The invention relates to an incinerator for crematories, including a combustion chamber provided with charge inlet, flue gas outlet, supply means for combustion air, heat supply means and ash outlet. The novelty resides in the fact that the combustion chamber is placed in a unit which is movable, between two positions, relative to at least one stationary end wall in which the charge inlet and the flue gas outlet are provided, and is divided into at least two compartments which communicate with each other at some distance from the flue gas outlet and are adapted to be positioned, one at a time, at respectively the charge inlet and the flue gas outlet. The heat supply means works in the compartment present at the charge inlet at just that moment, and the combustion gases from said compartment will pass the other compartment on their way towards the flue gas outlet.

  • Patent number: RE39442
    Abstract: An animal carcass incinerator designed to subject the entire external surface of the biomass material simultaneously to flame. The flame front burns inward toward the core of the material, greatly accelerating the burning process. Complete flame coverage of the biomass material is achieved by carefully shaping the internal surfaces of the incinerator. Burning gases are injected into a lower flame chamber. This lower flame chamber is bounded on its upper side by a grate, and on its remaining sides by the walls of the incinerator. Above the grate is a biomass chamber, where the animal carcasses or similar waste are deposited for incineration. The incinerator walls are lined with refractory insulating materials which incorporate a series of vertical flame channels. Likewise, the grate incorporates a series of vertical open channels. These channels are separated by raised ribs, which prevent the biomass materials from closing off the channels.
