Cremation Lesson 3

Opacity

The degree to which a substance allows light to pass through.

Settling chamber

a chamber designed to reduce the velocity of the products of combustion to promote the settling of fly ash to allow for further combustion or to inhibit escape from the stack.

Combustion

a chemical reaction that results from mixing fuel and oxygen in the presence of an ignition source and releases light and heat.

Burner

a device used to introduce flame to the primary chamber of a retort; may be referred to as the primary burner.

Crematory

a furnace or retort for cremating dead human bodies; a building that houses a retort

Flue

a horizontal passage for conducting products of combustion into the atmosphere.

Hearth

a solid surface upon which the human remains and container are places for the cremation process.

Stack

a vertical passage for conducting products of combustion into the atmosphere.

13. the secondary burner of a retort which facilitate additional combustion of the unburned combustible material that left the primary chamber.

afterburner

Cremation casket

an environmentally safe casket which is designed for encasing dead human remains for cremation.

15. a device used to introduce flame to the primary chamber of a retort; may be referred to as the primary burner.

burner

Secondary combustion chamber

chamber where unburned combustible materials from the primary chamber are completely burned.

Primary combustion chamber

chamber within a retort where primary ignition and burning of human remains occurs.

Pollutants

chemical compounds (gaseous or particulate matter) in combustion / flue gases that present human health and environmental concerns.

16. a chemical reaction that results from mixing fuel and oxygen in the presence of an ignition source and releases light and heat.

combustion

Emissions

combustion products such as smoke, soot, sulfur dioxide, etc.

see Afterburner.v

31. a chamber designed to reduce the velocity of the products of combustion to promote the settling of fly ash to allow for further combustion or to inhibit escape from the stack.

settling or expansion chamber

Particulates

small pieces of liquids or solids that include dust, fumes, smoke, mists or sprays that are products of incinerated matter.

Refractory

special high temperature lining of the combustion chambers.

32. a vertical passage for conducting products of combustion into the atmosphere.

stack

3. What material is often used for the metal identification discs of cremation?

stainless steel or titanium

5. Which burner is used to preheat the crematory?

the after burner or secondary burner

Retort

the burning chamber in a crematory.

Cremation container

the case / container in which the human body is delivered to the crematory and in which the body is cremated.

11. What should be done if the cremated remains will not fit into 1 urn?

the operator will utilize 2 urns and return both back to the family

Pulverize

the process of reducing the size of cremated remains after or as a secondary step of cremation.

Afterburner

the secondary burner of a retort which facilitate additional combustion of the unburned combustible material that left the primary chamber.

After chamber

the secondary chamber of a retort where unburned combustible materials from the primary chamber collects for further combustion.

12. What is the only approved method for shipping cremated remains?

the us postal service

6. Why do you preheat the crematory prior to cremation?

to ensure that the secondary chambers heat high enough to combust the gas particles released from the primary chamber during cremation

Commingled

to join or mix together.

4. What must be on the metal discs that are inserted into the crematory prior to cremation?

-a non repeating number that is assigned to each decedent

9. Following the removal of the cremated remains (Bone fragments) from the primary chamber, what is removed from the cremated remains?

-any metal that may have remained after the cremation process (remove with magnet).

1. What medical devices need to be removed prior to cremation?

-implants -pacemakers -defribrillators -infusion pumps -radioactive devices -artificial limbs -braces
