Question

Explosions can occur when electricity ignites explosive gases in the air, such as methane or natural gas.

Answer 1

Hi..

Here is your answer..

In any given gas and air mixture, the flame gets to the

point of sustaining itself when enough of the gas is there to have combustion

and spreads due to ignition.

There is an upper and a lower limit of being flammable, of

course, high and low, for the flammable gas that will help in combustion. The downward

limit is directly proportional to least amount of gas that will give out enough

for the flame to be self-sustaining.

Adding more gas will make the flame bigger giving out more

heat with increased chances of explosion when the mixture ignites.

 For the methane and air mix, the amount present there,

becomes so huge that the flame is not sustained since the oxygen supply is not

enough. Exceeding upper limit gas concentrations, the flame will not be

sustainable due to lack of oxygen.

So the answer to this question is “Yes”, provided the ratios of gas and air mixtures are in correct order.
