Energy for ignition

The igniter can be of several types, including a fuse wire, spark, or chemical ignition system. A typical energy for ignition is 10 J, although... 

Fig. 55. Variation of the minimum light energy for ignition of lead styphnate with ambient temperature, according to McAuslan [53]. x — ignition o—no ignition.

The energy for ignition varies withivoltage and overvoltage, but the trend of variation is not the same for all explosives...

The capacitance and the energy for ignition of people and of common objects are important. The capacitance of a human being is sufficient to ignite various flammable gas mixtures at commonly attained static voltages. 

Figure 21. The relationship between light energy for ignition and temperature for lead azide [119]. The solid line gives the experimental curve the dotted line connects the value for the ignition energy at 20° C and the point on the temperature axis corresponding to the thermal ignition temperature.
