Understanding Basic Combustion
A Definition:
Combustion is the rapid oxidation of a fuel resulting in the release of usable heat and the production of a visible flame
Natural Gas With Air:
CH4 + 2O2 + 8N2 ----------->
CO2 + 2H2O + 8N2 + 1000 BTU Heat
Perfect Combustion Provides:
The hottest flame
Minimum exhaust volume
Characteristics:
Characteristics:
Characteristics:
Air remaining after the fuel has been combusted-or-Air supplied in addition to the quantity needed for stoichiometric combustion
Primary Air --
Air mixed with the fuel prior to ignition
Secondary Air --
Air supplied to the flame after it is ignited
Secondary Air Effects --
