Spark (fire)

Fires may produce sparks as updrafts carry particles of the burning fuel aloft. This was a great problem with steam locomotives as the sparks might set fire to the adjacent landscape or even to the train itself, especially if the engine burned wood rather than coal. To prevent this dangerous nuisance, a variety of spark arrestors were invented and fitted.

Minimum Energy for Ignition

The influence of small fractions of methane in the air on the minimum electric spark ignition energy (MIE) for coal dust clouds was investigated systematically by Franke (1978).He found substantial reductions in the MIE, by factors of the order of 100, when the methane content in the air was increased from 0 to 3 vol%. Pellmont (1979) found a similar quite substantial effect on MIE for some
