Cremation Furnace

Navigating the world of funerals and funeral preparations can be challenging, especially when you're dealing with the grief of losing a loved one. One essential element often requiring clarity is the cremation process, and at the heart of this process is the cremation furnace. This post will discuss the cremation furnace in detail, shedding light on its operation, significance, and more.

What is a Cremation Furnace?

A cremation furnace, often referred to as a crematory, cremation chamber, or retort, is an industrial-grade furnace designed specifically for cremating human and animal remains. Constructed with fire-resistant bricks and materials, the high-powered furnace incinerates the body to ashes using extremely high temperatures.

The Functioning of a Cremation Retort

Before cremation, the deceased's body is placed in a casket or a container, which is then positioned into the chamber of the cremation furnace. The furnace typically operates at temperatures between 1400 to 1800 degrees Fahrenheit. The entire cremation process lasts for about two to three hours, depending on the size of the body.

• Preheating: Initially, the furnace is preheated for about an hour.
• Cremation: Once preheated, the body is placed into the furnace and incinerated.
• Cooling Down: After the incineration process, the remains are left to cool down.
• Collection: The cooled ashes are collected, processed, and handed over to the family in an urn or container.

Cremation Furnace Example:

Let’s walk through an example: Imagine you are attending a viewing ceremony with a closed casket. After the ceremony, the staff at the crematorium will place the casket into the cremation chamber. The chamber, pre-heated to about 1600 degrees Fahrenheit, will incinerate the body, reducing it to ashes and small bone fragments.
