Frequently Asked Questions Cremation

  • What is a cremation?

    What is a cremation? And why do we perform cremations? Well let’s start with some history about cremations. Those have first evidence at least dating from 20,000 years ago in our archaeological records. The Mungo Lady, the remains of a partly cremated body found at Lake Mungo in Australia. Alternative death rituals emphasizing one method of disposal of a body-inhumation (burial), or exposure-have gone through periods of preference throughout history. In the Middle East and Europe, both burial and cremation are evident in the archaeological record in the Neolithic era.

    What is a cremation today?

    In the modern day a cremation of a human or pet is a hygienic and fast way to have “ashes to ashes, dust till dust”. A cremation is to cremate a human or pet in a fire combustion, vaporization and oxidation of dead bodies to basic chemical compounds, such as gases, ashes and mineral fragments retaining the appearance of dry bones in a cremation furnace. And is a alternative way for a funeral or post-funeral rite as an great green alternative to the interment of an intact dead body in a coffin, casket or shroud. Cremated remains aka “cremains” or simply, “ashes” which do not constitute a health risk, may be buried or interred in memorial sites or cemeteries, or they may be retained by relatives and dispersed in various ways.

  • What is a cremation furnace?

    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.

    How is a body cremated in a cremation furnace?

    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.

    A cremation furnace is environmental friendly

    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.

  • What about the cremation process?

    How the cremation process is preformed by a professional crematorium. A cremation is preformed when all legal paperwork issued, everything is approved to carry out the cremation.

    Start cremation process

    The start of the cremation process is first to heat the second combustion chamber to a minimum of 820 degrees Celsius. The main combustion chamber will be heated to a 650 degrees Celsius. Before the coffin is inserted into the cremation furnace. After the coffin has been entered and the funeral coffin flames, the temperature in the combustion camber will increase during the process to approximately 1100 degrees Celsius. The cremation process is fully automated nowadays. Special cremation software has been developed to control this process. As a computer keeps tracks of what is happening in the cremation oven and can, if necessary, ensure that the right temperatures that achieve an optimal cremation process.

  • What is a technical cremation?

    What is a technical cremation? A technical cremation is a normal cremation but without any funeral services for families in a crematory. When a technical cremation is performed in a crematory, a small group of the family can be present to give there last respects. When the small group leaves the crematory, the deceased with coffin is transported to the human cremator.

    Growing interest for technical cremation

    Last years more and more people choose for the technical cremation. Important reason is the price, which is cheaper. Of course the final costs depend on the funeral home or crematory who will lead the funeral service.

  • What is the delivery time of a cremation furnace?

    What is the delivery time of a cremation furnace? This answer depends on the requirements from the crematory. Normally spoken the delivery time of a human cremation furnace is, approximately three months.

Our human cremators are the best in the world. What means that we build the heaviest available human cremator on the market these days. This 17 tons human cremator has a long life time cycle of ten years or more.

  • What is the difference between cold and hot start cremators?

    What is the difference between cold and hot start cremator? Here in Europe we know the difference between hot and cold start human cremators. A cold start cremation furnace is a cremator that start it’s first cremation of the day with a cold primary cremation chamber. For the following cremations the temperature is cooled down till 450 degrees Celsius. Before the next cremation can be done. This is because a cold start cremator could have (and is optional) a automatic charging bier. And therefore it’s to hot to insert a coffin manually. Cold start cremators are a good investment for crematories that do maximal 750 cremations per year. The environmental chamber is standard for every cremator 820 degrees Celsius.

    Difference between cold and hot start cremators

    The hot start cremator is one a crematory should choose when the crematorium is performing 750 cremation or more per year. This kind of cremation furnace is made for 6 cremations per day, based on a 8 hour shift. You could perform more when you have longer working hours. These hot start cremators are standard performing a cremation with as start the main cremation chamber has a 650 degrees Celsius. These hot start cremators come with a automatic charging bier. Therefore a hot insert of the coffin is possible. The maximum temperature of a human cremator lies between 1100 and 1250 degrees Celsius. Both are innovative cremators: the cold start cremator and the hot start cremator are a good investment for crematories around the world. Even the pet cremation furnace the DFW 100 is a cold start pet cremator.
