CHARACTERISTICS OF GAS FUELS
Each of the four types of gas has a specific boiling point (see Figure
By itself, gas cannot be ignited. Fuel, oxygen, and heat are necessary for combustion to occur. Remove one of these, and combustion cannot take place (see Figure

Gases will ignite at temperatures between 900˚F and 1200˚F.
A proper mixture, or ratio, of gas and air is needed to produce a flame. If the
