Correctly seasoned logs may also be more expensive. The logs that many individuals Examine the price of to pellets have moisture information of among forty-50%. So these cheap logs are Nearly fifty percent water, and as we all know water doesn’t burn up quite perfectly. Wet logs result in minimal combustion performance, very low heat and elevated smoke and ash. Hence with wood pellets, a huge amount of fuel pellets final a lot longer than a huge amount of wood. Consequently on a price comparison foundation you must Evaluate by warmth produced, not by weight. With a heat-generated basis the price of wood pellets is quite aggressive to logs. This also isn't going to factor into some great benefits of been capable to use pellets in highly automated wood pellet stoves and boilers.

By way of example wood pellets constantly have humidity content under ten%, and in many instances it really is lower than this at throughout the 5-8% mark. It is possible to be confident of this point, as its extremely hard to get a pellet to possess a significant density and easy floor with larger humidity content. Even so, wood logs are sometimes marketed with pretty much no drying going down. Make sure you Observe a seasoned log usually takes about two years to dry and in some cases then you remain taking a look at humidity content material of minimum 25%.

When This can be the case, far more of the wood's inherent Strength must be used solely on evaporating dampness, as compared to the drier coal, which means that the amount of CO2 emitted per unit of developed heat might be larger.[sixty one]
To produce wood pellets, you'll want to get ready the All set wood sawdust, sizing three-5mm, dampness ten-15%. And feed the sawdust to the pellet device, the pellet machine will press the sawdust In the pelletizing home, the final pellets will push out within the pellet machine ring die holes.
