We will give an exact explanation of how and why the quality of one of the most modern ways of heating today is so important. It is a type of solid fuel in the form of cylindrical granules, which are produced from wood waste. Pellet heating has some advantages such as the small waste product from combustion, as well as the automatic supply of fuel to the burner.
We at SchneiderPellets have located our company at the foot of the Rila Mountains in the town of Samokov. It is from one of the most beautiful points in Bulgaria that we get the raw material for our pellets. We use only quality coniferous wood, and our production capacity for one year is over 20,000 tons.
Stages of production
In order to reach the final product, the pellets must first go through several stages of processing. Initially, the wood is ground into large pieces and allowed to dry. The reason for the large crushing is the shorter time it takes for the material to dry.
Two types of mills are used for this grinding – drum type or hammer mills. A new grinding follows, which this time makes the wood in small pieces. Hammer mills are most often used here. At the end of the stage, particle uniformity must be achieved – up to 4 mm. One of the most important stages is pressing – there is the formation of wood pellets. The ground and dried wood is fed to a granulator through a dispenser and thus the granules are formed. The pressing takes place at high pressure and temperature of over 100 degrees. The lignin contained in the wood is the natural glue that softens at a similar temperature.
After drying, the granules have a temperature between 70 and 90 degrees, and this temperature depends on the pressing force. The pressing force is decisive for quality pellets.
When the strength is higher, this makes the temperature higher, and this determines how high the quality of the pellets will be. However, once the process is complete, the pellets need to be cooled. For this purpose coolers are used, through which the final hardening of the wood granules is achieved. Only then are the granules suitable for storage and transport.
Quality standards A1 and A2
In order to have quality pellets, it is good to pack them and then store them in pre-prepared storage rooms. It is recommended that these places be clean (dry) and ventilated. We at SchneiderPellets can boast the EN Plus brand. But what does that mean? In 2010, the EU introduced a uniform quality standard for wood pellets for heating (EN 14961-2). This standard affects parameters such as granule length, diameter, ash, moisture content and others. With the adoption of this quality standard, an EU EN Plus certificate is introduced, which is intended for pellets used for domestic use. ENplus distinguishes the qualities of two – A1 and A2.
CHARACTERISTICS OF WOOD PELLETS
For class A1, the strictest possible restrictions for ash content in quality pellets have been introduced, and in our country it is up to 0.69%. In class A2, the ash content may be up to 1.5%. Characteristics of the wood pellets of “SchneiderPellets”: – 100% softwood without chemical impurities. – Heat output – 5.1 kWh / kg – Burning ash – up to 0.69% – Diameter – 6 mm – Length – up to 35 mm – Moisture – 5.5% – Sulfur – 0.0014%
