What are the basic requirements are to be present when a fuel undergoes combustion? |

Answer» In order that a fuel undergoes combustion, three basic requirements are to be present • A combustible substance: All carbon compounds are combustible, but carbon as diamond is not. Petrol is a combustible substance. • A supporter of combustion: Atmospheric air or oxygen gas is a supporter of combustion. In their absence, combustion will not be supported. Carbon dioxide or nitrogen gases do not support combustion. • Heating to ignition temperature: A minimum amount of temperature or heat is required to enable a fuel to catch fire. Coal has a high ignition temperature; a matchstick cannot produce enough heat to ignite it. However, a matchstick can ignite paper or LPG gas as it has low ignition temperature. |
