LEL & Flash Point Calculations

Lower Explosive Limits and Flash Point Calculations:

H O   +   O2  =   CO2  +   H2O
Antoine Coefficients for Component

Flammability ranges increases with temperature.
Do you wish to estimate the LEL and UEL at a temperature other than 25 deg.C?
Temperature, deg. C.
Heat of Combustion, kcal/mole

The UFL increases with pressure increases. Pressure has little affect on the LEL.
Do you wish to estimate the UFL at a pressure other than atmospheric?
Pressure, psig
