||A medium Btu gas containing methane and
carbon dioxide, resulting from the action of microorganisms
on organic materials such as a landfill.
||The waste combustible gas generated in a blast furnace when iron ore is being reduced with coke to
metallic iron. It is commonly used as a fuel within steel works.
|British Thermal Unit (Btu)
||The quantity of heat required to raise the temperature of 1 pound of liquid water by 1 degree Fahrenheit at the temperature at which water has its greatest density (approximately 39 degrees Fahrenheit).
||The mixture of permanent gases produced
by the carbonization of coal in a coke oven at temperatures in
excess of 1,000 degrees Celsius.
||A gas obtained by destructive distillation
of coal, or by the thermal decomposition of oil, or by the reaction
of steam passing through a bed of heated coal or coke. Examples
are coal gases, coke oven gases, producer gas, blast furnace gas,
blue (water) gas, carbureted water gas. Btu content varies
||A mixture of propane and air resulting in a gaseous
fuel suitable for pipeline distribution.
||Noncondensate gas collected in
|Supplemental Gaseous Fuels Supplies
gas, propane-air, coke oven gas, refinery gas, biomass gas, air
injected for Btu stabilization, and manufactured gas commingled
and distributed with natural gas.
|Synthetic Natural Gas (SNG)
||(Also referred to as substitute natural gas) A manufactured product, chemically similar in most respects to natural gas, resulting from the conversion or reforming of hydrocarbons that may easily be substituted for or interchanged with pipeline-quality natural gas.
