Fuel pellets are one of the modern types of solid fuel, actively used in special pellet boilers for heating residential buildings and commercial and industrial facilities. They retain heat well and are highly efficient.
The main advantage of straw pellets is their low moisture content (W), which is only 8–10%, compared to a more classic type of fuel, such as firewood, which has a moisture content of 30%. Due to this, less heat is spent on evaporating moisture during combustion, which, in turn, affects the calorific value: for straw pellets, it averages 17 MJ/kg, and for firewood (W 30%) – 12 MJ/kg (the more indicator, the more heat we get from fuel combustion). For example, 1 ton of fuel pellets is enough to produce 4000 kW/h of thermal energy, and the combustion of 1 ton of wood (W 30%) will deliver approximately 3,400 kW/h.
Agropellets, including straw pellets, are among the most renewable, eco-friendly fuel materials globally. Due to its much shorter growth phase, straw is a much safer and more stable raw material than wood. When burning, straw pellets emit 15 times less CO2 into the atmosphere than natural gas since, during ripening, the crop absorbs the same amount of carbon dioxide as it can release during combustion.
The following conditions must be provided at the place of their storage to keep pellets in good condition:
• Dryness and sufficient ventilation of the room;
• High level of fire safety;
• Protection from direct sunlight;
• Stand (it is better to use pallets or wooden boards).
