What is a cremation furnace? A cremation furnace is also called a: “incinerator“, “cremator” and “cremation oven”. A human cremation furnace is used in a crematorium. The cremation or incineration of a dead body is carried out in a cremation furnace at a temperature ranging between 1000 to 1300 degrees Celsius. The intense heat helps reduce the body to its basic elements and dried bone fragments. The cremation process takes place in a cremation chamber, also known as a retort, of a crematory. The chamber is preheated at a set point 800 degrees Celsius and then the coffin with body is placed into the main cremation camber from the cremation furnace. This happens quickly through a mechanized charging bier to avoid heat loss. The cremation furnaces of DFW Europe are very innovative and are high-tech cremation solutions. The cremation furnaces of DFW Europe are the best a crematorium can buy, due to it’s energy efficiency and it’s cremation filtration system.
During incineration, the body is exposed to a column of flames produced by a furnace burner that is fueled by natural gas, bio-oils, electricity or hybrid. As a corpse is placed in a casket or container (preferably made from combustible materials), the coffin burns down. Next, the heat dries the body, burns the skin and hair, contracts and chars the muscles, vaporizes the soft tissues, and calcifies the bones so that they eventually crumble. The gases released during the cremation process are discharged through an exhaust system. The bodies are always cremated one at a time. Exeptions are made with mother and child or baby twins. There is no smell because the emissions are processed thru an cremation filter system to destroy the smoke and vaporize the gases that would smell.
Some crematoria have a secondary afterburner to help burn the body completely. Otherwise, the cremation technician may have to assist. It is then collected in a tray or so called ash pan and allowed to cool for some time in a ash pan refrigerator. These remains, however, also contain non-consumed metal objects such as screws, nails, hinges, and other parts of the casket or container. In addition, the mixture may contain dental remains, dental gold, surgical screws, prosthesis, implants, etc. These objects are removed with the help of strong magnets and/or forceps after manual inspection. All these metals are later disposed. Mechanical devices, pacemakers, in particular, are removed beforehand because they may explode due to the intense heat and can damage the cremation camber floor and crematory staff.
It is suggested to remove jewellery items like rings, wrist washes, and other similar objects, too, as they are likely to break down during the process. Moreover, the metal pieces are removed before the next process because they may damage the equipment used for pulverization. Finally, the dried bone fragments are further ground into a finer sand-like consistency. The machine used for this pulverization is called cremulator. On an average, it takes about one to three hours to cremate a human body, thereby reducing it to 3-7 pounds of cremains. The cremation remains are usually pasty white in colour. These remains are transferred in a cremation urn and given to the relative or representative of the deceased. If you do not have an urn, the crematorium may return the ashes in a plastic box or temporary default ash container.
