Vocabulary- Cremation Flashcards
The pressure difference between the cremator or any component through the gas passages of the cremator to the atmosphere.
Draft
The pressure difference created by the action of a fan, blower, or ejector, which is located between the incinerator and the stack, or at the stack exit.
Induced Draft
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
Chamber within a cremator where unburned combustible materials from the primary chamber are conveyed to facilitate additional combustion. Sometimes referred to as a secondary burner.
Afterburner
Special high temperature lining for the combustion chambers.
Refractory
The process of reducing the size of the cremated remains after cremation.
Pulverize
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
The process of reducing the body to ash and bone fragments through flame, heat and vaporization.
Cremation
Any refractory construction intended to change the direction of flow or velocity of the products of combustion.
Baffle
The amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit at or near maximum density.
BTU (British Thermal Unit)
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 include Afterburner, Primary Burner, and Secondary Burner.
Burner
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
All is supplied to the equipment for combustion, cooling, ventilation, etc.
Air
The pressure difference created by the action of a fan, blower or ejector, which supplies the primary combustion air above atmospheric pressure.
Forced Draft
A device in the stack which responds to the detection of smoke by setting off of an alarm and/or taking some type of corrective action.
Smoke Alarm
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 gasses, checker work and/or turns indirection of the gas flow.
Mixing Chamber
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.
Secondary Air
Combustion products such as smoke, soot, sulfur dioxide, etc.
Emissions
Sensor that provides the presence of flame.
Photo Cell
Chamber where unburned combustible material from the primary chamber are completely burned.
Secondary Combustion Chamber
