Cremation Vocabulary Flashcards
Test conducted by federal state, or local regulatory agencies to measure pollutants released into the atmosphere from a crematory, in amounts that exceed regulatory requirements.
Source Test
Hearth on which drying or combustion results from the action of hot combustion gases passing only over the top surface of the hearth.
Cold Hearth
All gases which leave the cremator by way of the flue, including gaseous products of combustion, water vapor, excess air and nitrogen.
Flue Gas (Products of Combustion)
Chamber within a cremator where unburned where unburned combustible materials from the primary chamber are conveyed to facilitate additional combustion.
Afterburner (Secondary Burner)
Chambers or gas passage placed between two chambers to carry the products of combustion in a downward direction.
Downpass
A system on some cremators that monitors the visibility (opacity) through flue gases as they enter the stack. This detects the presence of smoke (possible pollutants) and is designed to allow the operator to correct the operating conditions.
Pollution Control System (PCS)
A smaller gas burner used to light the main burner.
Pilot
United States Environmental Protections Agency
EPA
The degree to which a substance allows light to pass through.
Opacity
Chamber where unburned combustible material from the primary chamber is completely burned.
Afterchamber
Any air, controlled with respect to quantity and location, forced or induced, supplied to the cremation chamber for the purpose of promoting combustion of the combustible materials in the chamber.
Primary Air
A unit of pressure.
PSI (Pounds per Square Inch)
Chamber usually placed between the primary combustion chamber and the secondary combustion chamber where thorough mixing of the products of combustion is accomplished by turbulence created by increased velocities of gases, checkerwork and/or turns indirection of the gas flow.
Mixing Chamber
Hearth on which drying or combustion results from the action of hot combustion gases passing over both the top and bottom of the hearth.
Hot Hearth
A chemical reaction that results from mixing fuel and oxygen in the presence of an ignition source (heat, flame, spark, etc.) and releases light and heat.
Combustion
Combustion products such as smoke, soot, sulfur dioxide, etc.
Emissions
The heating process of reducing the body, wrapping and/or the container to their basic elements in the form of cremated remains through combustion.
Calcination
The pressure difference between the cremator or any component part and the atmosphere which causes a continuous flow of air and products of combustion through the gas passages of the cremator to the atmosphere.
Draft
Sensor that provides the presence of the flame.
