Wood heating however the use of logs is a long established form of solid fuel heating using logs. On the other hand, now the wood pellet has arrived on the market place. Some consumers yet are not clear on the advantages of biomass pellets compared to combustion logs, plus cannot see the benefits in either fee or heat. Here is a comparison of pellet vs biomass logs. Biomass logs have customarily been used for heating, on the other hand very rarely are biomass logs used at a complete heating solution. The reasons for this are simple, time, required maintenance, sufficient fuel storage along with fuel consumption. Loading a wood log heating system is very time consuming, plus getting the fire going can take up to half an hour. Constant loading of the fire every few hours is required, making it difficult to do other things plus remember the best up the fire. Also, as a fuel source, logs are by way of no means ideal. Firstly, to get a reasonable burn the wood must be seasoned to around 30% moisture content. This can take several years to achieve this moisture content, as it log form the moisture is well protected. Therefore a large volume of drying wood along with dry biomass for use needs to be stored. Yes, some consumers purchase dried logs, on the other hand when you actually compare the figures between dry logs as well as pellets, there is a clear winner. As wood pellets have a much lower moisture content plus lower density, measuring charge per heating value biomass pellets are cheaper than purchasing dried logs. So you would be essentially be paying more for a energy that generates less warmth plus required much more work.

One of the key factors in a pellet vs wood comparison is automation, or specially lack of automation by way of wood log heating systems. A pellet system generally can hold at least a days worth of fuel, as well as in many cases more than a few days. Hopper extensions are common to take the fuel capacity of the unit up to a week, plus external hoppers can be used to hold up to a years worth of energy. Now compare this to wood lo heating systems, and not just the additional work required but the time. Due to the hopper system, a adaptable speed timed auger can meter energy into the fire to control the heat to a specific set level via a thermostat. A log stove cannot really control temperature as there is no control over fuel resource. Wood pellet systems have the processes required to fit the modern lifestyle.

Biomass logs or chips can be processed into pellet fuel via a series of processes. Primarily, shredding the biomass to a suitable size for the wood pellet press is required. Also note that a wood pellet press is also known as a wood pellet appliance or biomass pellet mill. Once shredded the sawdust is then monitored for moisture if above 15%, drying will be required, usually using waste wood as the energy source for the dryer. Once dry, on many large scale pellet plants, the wood is first conditioned before it enters the pellet mill. This can mean quite a few things, in many cases it refers to heat treatment via dry steam to start the melting process of the natural lignin within the wood to bind the pellets together. The matter then enters the mill.
