Virgin Wood Pellets: Additional Information

Detailed Description

Virgin Wood Pellets Silver Fir is a premium renewable biofuel designed for efficient, clean, and reliable heat production. Produced at the own manufacturing facilities of Strobile Energy, Virgin Wood Pellets Silver Fir are made from carefully selected silver fir wood shavings collected from the residues of other wood-processing industries. This allows the company to create a high-quality fuel product from clean virgin wood raw materials without the use of additives or artificial binders.

One of the main advantages of Virgin Wood Pellets Silver Fir is their light, almost white color. For many customers in the European market, white pellets are associated with clean raw material, low contamination, and premium pellet quality. The light color of Virgin Wood Pellets Silver Fir reflects the careful selection of silver fir wood and the absence of unnecessary impurities such as bark, dirt, or foreign particles. As a result, the product has an attractive appearance and meets the expectations of buyers looking for clean and consistent pellet fuel.

Another important benefit of Virgin Wood Pellets Silver Fir is their high calorific value. This means the pellets provide strong and efficient heat output, making them a practical substitute for natural gas in many residential and commercial heating applications. Due to their dense structure and quality raw material, Virgin Wood Pellets Silver Fir burn evenly and deliver stable energy performance in pellet stoves and pellet boilers of different capacities. For end users, this means dependable heating and convenient everyday use during the heating season.

Virgin Wood Pellets Silver Fir are also valued for their clean combustion and low ash content. Low ash is one of the most important quality indicators for pellet fuel because it helps reduce cleaning frequency and supports more comfortable operation of heating equipment. Pellets with low ash content help keep burners, combustion chambers, and ash containers cleaner, which is especially important for households and businesses that use pellet heating systems on a regular basis. Thanks to these properties, Virgin Wood Pellets Silver Fir are a convenient solution for customers who want efficient heating with less maintenance.

The product is manufactured in a 6 mm format and packed in practical 15 kg sacks, which makes storage, transport, and handling easier for private consumers, retailers, and distributors. Virgin Wood Pellets Silver Fir are suitable for pellet stoves of different power and can be supplied to a wide range of buyers, including households, local resellers, acquisition groups, and companies in different regions. Strobile Energy also offers delivery by truck, providing flexible logistics solutions for domestic and export customers.

Throughout the year, Strobile Energy supplies Virgin Wood Pellets Silver Fir to different customer groups. Demand for wood pellets is usually seasonal, and the market price often changes during the year. In many cases, the best offers are available from March, while prices tend to increase gradually from April to September as the heating season approaches and demand rises.

Virgin Wood Pellets Silver Fir combine premium appearance, high calorific value, clean raw material, and low ash content in one product. For customers looking for reliable white wood pellets for efficient and clean heating, Virgin Wood Pellets Silver Fir are a strong and competitive choice.

FAQ
Why does the Virgin Wood Pellets specification show two calorific values — 4.88 and 5.26 kWh/kg?

Both figures describe the same pellets, but they are calculated on a different basis.

  • 4.88 kWh/kg (17.57 MJ/kg)— net calorific value as received. This is the energy you actually get from 1 kg of pellets in the state they arrive at your boiler, i.e. with their natural moisture content of 6.4%. This is the value regulated by EN ISO 17225-2: for class A1 it must be at least 16.5 MJ/kg (4.6 kWh/kg). Our pellets exceed this minimum by 6.5%.
  • 5.26 kWh/kg (18.94 MJ/kg)— net calorific value on a dry basis. This is the energy potential of the wood itself, without water. It reflects the quality of the raw material: pure European silver fir (Abies alba Mill.) without bark or additives has one of the highest calorific values among softwoods, and our figure is close to its practical maximum (≈ 19 MJ/kg dry basis).

Why the difference?

During combustion, part of the energy is spent on evaporating the water contained in the pellets. ISO 18125 converts one value into the other:

Q(as received) = Q(dry) × (1 − M/100) − 0.02443 × M

For our pellets: 18.94 × 0.936 − 0.156 = 17.57 MJ/kg.

What it means in practice:

  • 1 tonne of Virgin Wood Pellets delivers about 4,880 kWh of heat, roughly the same energy as 480–500 m³ of natural gas.
  • Low moisture is our advantage: the same wood at the class A1 moisture limit of 10% would give only ≈ 16.8 MJ/kg (4.67 kWh/kg). At 6.4% moisture our pellets carry ≈ 4.6% more energy in every kilogram.
  • Tip for buyers: when comparing offers from different producers, always ask on which basis the calorific value is stated. Figures of 5.0–5.3 kWh/kg almost always refer to the dry basis or to the gross calorific value. A fair comparison is only “as received vs. as received”.
