Does body size have any affect on the cremation process?
Yes. Bodies larger than 300 pounds or with a high fat content can create an abnormally high combustion rate, which can cause visible emissions to be emitted from the stack. This can be controlled by starting with a cool cremation chamber, heating the secondary chamber to 1400-1600 F prior to ignition, and then briefly igniting the human remains and container to allow the body to burn down on its own fuel. After approximately one hour, normal operating procedures can be resumed.
