Properties of Liquid Fuels
Flash Point |
: |
Minimum temperature at which liquid fuel will produce sufficient vapors to form a flammable mixture with air. Indicates maximum temperature at which liquid fuel can be stored without any fire hazard. |
Fire Point |
: |
Minimum temperature at which liquid fuel produces sufficient vapors to form a flammable mixture with air that continuously supports combustion establishing flame instead of just flashing. |
Smoke Point |
: |
Measure of the tendency of a liquid fuel to produce soot. |
