Solid fuels leave more smoke and ash on burning

Solid fuels, such as coal, wood, and charcoal, leave more smoke and ash on burning compared to liquid or gaseous fuels. This is because of the composition of solid fuels, which contain impurities such as sulfur, nitrogen, and ash.

Smoke production:

When solid fuels are burned, the impurities present in them produce smoke. This smoke contains harmful gases such as carbon monoxide, sulfur dioxide, and nitrogen oxides, which can lead to respiratory problems. The smoke also contains soot, which is a fine black powder that is a result of incomplete combustion of the fuel.

Ash production:

Solid fuels also produce more ash on burning compared to liquid or gaseous fuels. The ash is a result of the minerals and impurities present in the fuel. The amount of ash produced depends on the type of fuel and the combustion conditions. Ash can cause pollution and can also damage the environment.

Conclusion:

Solid fuels leave more smoke and ash on burning due to the impurities present in them. This is why it is important to use cleaner fuels such as natural gas or electricity, which produce less smoke and ash on burning and are better for the environment.
