Study Questions and Answers
Combustion - Ans:✔✔-Described by CANA as the act or instance of burning, and involves a chemical
reaction in which oxygen is rapidly combined with fuel, giving off heat
Perfect Combustion - Ans:✔✔-a result of mixing and burning the exact proportions of fuel and oxygen so
that no unburned fuel or oxygen remains.
Two phases of the perfect combustion - Ans:✔✔-- primary combustion in the ignition chamber. Most
cremationists refer to this as the primary chamber
- secondary combustion- where the products of the combustion process settle and are further
combusted. Ultimately the remaining gases will discharge from the crematory stack.
Opacity - Ans:✔✔-degree to which light is reduced when viewed through a smoke plume of visible
emissions
According to the EPA visible emissions that consist of smoke and flame are indicators of: - Ans:✔✔-
improper combustion and excessive particulate emission

Charging Door - Ans:✔✔-door to the primary chamber typically electrically or hydraulically operated
Primary Chamber - Ans:✔✔-- where actual cremation takes place
- heat and air are mixed creating combustion
- 1400 to 1800F
-ideal temperature is 1600F
Secondary Chamber - Ans:✔✔-- holds unburned combustion from primary chamber until complete
combustion is achieved
- allows proper and controlled air flow to the stack
- 1400 to 1800 is acceptable with the more ideal temperature being 1650-1700F
- It is important the secondary chamber run at least 50 degrees hotter than the main chamber for
drafting and airflow protection
Hearth - Ans:✔✔-floor of the crematory
Refractory Material - Ans:✔✔-- specialized material designed to withstand high temperatures
- Lines the interior of the crematory
