Crematorium oven

Abstract

The invention relates to a crematorium oven 1 comprising at least one combustion chamber 2 with a ceiling, wall 2.1 and base 3 on which to place the object to be cremated, a heat supply system 4, a combustion air supply 5 and a flue gas outlet 6. Within the ceiling and / or the wall 2.1 and / or the base 3 of the combustion chamber 2 at least one combustion air supply channel 7 and at least one flue gas return channel 8 are provided whereby the flue gas return channel 8 in the ceiling, and / or the wall 2.1 and / or the base 3 has an inlet 8.1 and an outlet 8.2. In the ceiling and / or wall 2.1 and / or in the base 3 of the combustion chamber 2 the at least one combustion air supply channel 7 opens into the at least one flue gas return channel 8, so that with the supplied combustion air a suction effect of the combustion air supply into the combustion chamber 2 is brought about. In this way at least part of the flue gas produced during the combustion process is drawn into the inlet 8.1 of the flue gas return channel 8 and emitted through the outlet 8.2 of the flue gas return channel 8 into the combustion chamber 2 and is thereby supplied to the combustion process again.

Description

TECHNICAL FIELD[0001]The present invention relates to a crematorium oven.PRIOR ART[0002]Crematorium ovens are already known from the prior art. They essential comprise a combustion chamber with a ceiling, wall and base on which to place the object to be cremated, a heat supply system for heating the combustion chamber as well as a combustion air supply and a flue gas outlet.[0003]Crematorium ovens are also known which have a combustion chamber with two combustion chamber sections, whereby in the first combustion chamber section preliminary incineration of the object to be cremated takes place, with subsequent incineration of the remains from the first combustion chamber section taking place in the second combustion chamber section. Here, the cremation remains from a first incineration phase remaining in a first combustion chamber section are transferred to the second combustion chamber section manually or with a removal device, whereby the heat produced in the first combustion secti...

AI Technical Summary

Benefits of technology

The invention is a crematorium oven that increases efficiency and reduces energy requirements. It achieves this by using a flue gas return system and several combustion air supply channels that are strategically placed to target difficult to burn parts of the object being cremated. The flue gas return channels have inlets and outlets, and the outlet of one channel is placed above the inlet of another channel to ensure efficient heat exposure. The combustion chamber has two sections, with the first section designed for preliminary burning and the second section for subsequent incineration and ashes mineralization. The base of the combustion chamber has elevations to allow the object to be cremated to be at a distance from the base, which increases the heat exposure to the slow-burning areas. Overall, the invention achieves efficient and fast cremation with reduced energy requirements.

Problems solved by technology

The disadvantage of the solutions known from the prior art is that crematorium ovens have a low efficiency so that during combustion a high energy supply through the heat supply system is necessary and the fuel consumption is therefore high.

Furthermore the duration of a cremation is very long as it is determined by the difficult and slowly burning parts of the object being cremated.
