Q

A vertical (stack) or horizontal (flute) passage for conducting products of combustion to the atmosphere.

A

Chimney

21
Q

A device in the stack which responds to the detection of smoke by setting off an alarm and/or taking some type of corrective action.

A

Smoke Alarm

22
Q

Chamber within a cremator where primary ignition and burning of the remains occurs.

A

Primary Combustion Chamber

23
Q

The process of reducing the body to ash and bone fragments through flame, heat and vaporization.

A

Cremation

24
Q

Any air, controlled with respect to quantity and location, supplied through ports in the walls, roof of the secondary combustion chamber, for the purpose of completing combustion of the combustible materials in the gasses from the cremation chamber or to reduce operating temperatures within the cremator.

A

Secondary Air

25
Q

Any refractory construction intended to change the direction of flow or velocity of the products of combustion.

A

Baffle

26
Q

Excess air injected along the sides of the primary combustion chamber to assist the combustion process and allow the primary chamber to cool following the cremation process. Generally used during the second half of the cremation.

A

Hearth Air

27
Q

Sensor which detects or monitors proper ignition bases on the presence of ultraviolet rays from the flames.

A

Flame Scanner

28
Q

A device for the introduction of a flame by delivering fuel and its combustion air at desired velocities and turbulence to establish and maintain proper ignition and combustion of the fuel. Types of these include: afterburner, primary, and secondary.

A

Pollutants

48
Q

The pressure difference created by the action of a fan, blower or ejector, which supplies the primary combustion air above the atmospheric pressure.

A

Forced Draft

49
Q

The case/container in which the human body is delivered to the crematory and in which it is cremated. The container must conform to these guidelines: Be composed of a suitable material; be rigid enough for handling ease; assures protection of the health; provides proper covering for the remains; meets moral codes for respect and dignity.
