GLOSSARY:
COMBUSTION
The chemical action resulting from the direct combination of oxygen gas, generally in air, with a combustible material accompanied by the evolution of heat and light.
COMBUSTION CHAMBER
The structure immediately surrounding the combustion reaction and generally above the fuel (*) or refuse (*) grate and designed to support or promote the combustion reaction.
FUEL
A combustible material having good combustible properties such as a relatively low ignition temperature, a long burning time, and a minimum of impurities which hinder combustion and used primarily to produce heat.
INCINERATION
The combustion of refuse (*) for primary purpose of disposing of that refuse rather than for producing heat. NONCOMBUSTIBLE FLUID
A gas or liquid which itself does not burn but which is capable of supporting or promoting combustion (i.e., air, steam, or water).
REFUSE
A combustible waste material which is burned for the sole or primary purpose of disposing of that material.
