MOR 302 - Cremation Lesson 4 - The Cremation Process - DMACC

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)

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

Burner

How should infant pulverization be accomplished?

By hand

What is placed into the crematory primary chamber to facilitate the loading of the deceased?

Cardboard cylinder/roller

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

Combustion

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

Cremation casket

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

Cremation container

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

Crematory

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

Emissions

Which portion of the deceased (head or feet) should be loaded into the primary chamber first during a normal (non-obese) cremation?

Feet First

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

Flue

How should an obese case be loaded into the crematory- head first or feet first?

Head first

A solid surface upon which the human remains and container are placed for the cremation process.

Hearth

What may happen if the secondary chamber has to high of a temperature?

It could cause the gases and particulates to evacuate through the stack more quickly causing a visible emission from the stack

Should the cremation container be opened at the crematory?

No, the funeral directors should verify with the crematory that the container will not be opened without the funeral director present since the funeral director is the representative of the family

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

Opacity

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

Particulates

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

Pollutants

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

Primary combustion chamber

What unit is utilized to reduce the bone fragments down to a fine sand-like powder?

Processor

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

Pulverizing

Special high temperature lining of the combustion chambers.

Refractory

The burning chamber in a crematory.

Retort

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

Secondary Combustion 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.

Setting or expansion Chamber

What relative temperature should be used for an infant cremation?

Should utilize the heated crematory after a deceased person has been cremated

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

Stack

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

Stainless steal or titanium

What special consideration relative to the primary chamber is given to the cremation process of an infant?

The infant should be placed in a special infant pan alone close to the primary burner

Why is ambient heat (heat that builds up from other cremations) used for an infant cremation?

The intense heat could dissipate the cremated remains leaving nothing, because the babies are so tiny that normal burners and blowers would dissipate the cremated remains of the infant so ideally you would want to use a gentle heat for them

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

The operator will utilize 2 containers and return both to the family

Why do you preheat the crematory prior to cremation?

To ensure that the temperature in the secondary chamber is high enough to combust the gases and particulates released from the primary chamber

What medical devices need to be removed prior to cremation?

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

What clearance should an obese have between the container and the refractory?

1 inch clearance on top and sides of the primary chamber between the refractory and the cremation container

What temperature should the crematory have when cremating an obese deceased?

1400-1600 degrees but does not reach 2000 degrees

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

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

Afterburner

Which burner is used to preheat the crematory?

Afterburner

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

Afterchamber
