Liquid fuels are combustible substances that exist in liquid form and are used to obtain thermal energy. Examples of liquid fuels include gasoline, diesel, and kerosene. On the other hand, solid fuels refer to different forms of solid materials that can be burnt in order to release energy. Examples of solid fuels include: wood, hexamine fuel tablets, dry dung, wood pellets, corn, wheat, charcoal, peat, coal, rye, and other grains
Liquid fuels provide a number of benefits over solid fuels. Given below is a list of some advantages of liquid fuels over solid fuels.
The following are the advantages of liquid fuels over solid fuels:
- Liquid fuels can be used for internal combustion engines
- Liquid fuels can easily be transported
- Liquid fuels require less air for combustion
- Liquid fuels require less storage space compared to solid fuels
- Solid fuels contain a higher percentage of moisture and as a result of this, they burn with great difficulty. On the other hand, liquid fuels can be burnt with a fair degree of ease and achieve high temperatures very quickly compared to solid fuels
- The combustion of liquid fuels is uniform
- The disposal of solid fuels is a problem since it produces ash. On the other hand, liquid fuels leave no or very little ash after burning
- The firing of liquid fuels can be easily controlled which allows meeting the variation in load demand easily
- The handling of liquid fuels is much easier
- Their calorific value of liquid fuels is high
- Their combustion rate is easy to control
- They do not have any loss during storage
- They reach maximum temperature value in very less time
