Solid Fuel - Advantages and Disadvantages?

What is solid fuel? 

Solid fuel is a material that can be burnt to release energy, providing heat and light. Common examples of solid fuels include wood, charcoal, peat, coal, hexamine fuel tablets, dry dung, wood pellets, and other grains. Solid fuel takes up less space than liquid or gaseous fuels and is easier to handle.

Advantages of solid fuel:

1. Solid fuel takes up less space than liquid or gaseous fuels.
2. Solid fuel is easier to handle and transport.
3. Solid fuel requires fewer precautions during storage compared with other types of solid, liquid, or gaseous fuels because it does not spill as easily, but can still ignite if spilled on a hot surface.
4. Solid fuel is relatively stable and difficult to ignite accidentally.
5. Solid fuel is often less expensive than other fuels.

Disadvantages of solid fuel:

1. Solid fuel produces less energy than liquid or gaseous fuels per unit weight
2. Solid fuel emits more pollutants, including particulates and carbon monoxide than liquid or gaseous fuels
3. Solid fuel can create a fire hazard if not stored or used properly.
4. Solid fuel can be difficult to light.
5. Solid fuel can create soot and ash.
6. Solid fuel can cause respiratory issues because of its smoke.
