Why lpg and methane use as a ideal domestic fuel
Methane and lpg fairly high calorific value they burn with smokeless fire therefore they do not cause pollution .they are ideal use of domestic fuel.
Yes, because we cannot use other gases as domestic fuels, as they have irregular amount of flammable atoms, which makes them inflammable or highly inflammable. Liquified Petroleum Gas is a domestic fuel as it has fixed amount of flammable atoms. But methane cannot directly be used as a domestic fuel. The biogas has methane which makes methane suitable for domestic use.
