What are the most popular types of solid fuels used in boilers?

The most popular types of solid fuels used in boilers are:

1. Coal: This is one of the most popular types of solid fuels. Hard coal and lignite are widely used in boilers for heating homes, industrial plants and power plants. Coal is relatively cheap and available in many regions.

2. Wood: Wood is a traditional solid fuel that has been used for centuries. It can be in the form of firewood, wood pellets or briquettes. Wood is used in boilers to heat homes, especially in regions where it is available in large quantities. Often this fuel is produced on our farms by felling fruit or ornamental trees.

3. Pellets: Pellets are compressed lumps of natural materials such as wood, sawdust or plant biomass. They are commonly used in special pellet boilers that are efficient and eco-friendly. Pellets are easy to store and burn, making them a popular choice.

4. Coal briquettes: Coal briquettes are similar to pellets but are made of coal or a mixture of coal with other binders. They are used as fuel in boilers, particularly where coal is available in the form of lumps.

It is worth noting that the choice of the type of solid fuel depends on many factors, such as the availability of raw materials in a given area, costs, energy efficiency and ecological requirements.

Solid fuels are widely used in boilers to heat homes, industrial plants and power plants. They are not only a source of heat, but also play an important role in meeting the energy needs of various sectors of the economy. Choosing the right type of solid fuel is important from both an economic and ecological point of view.
