Comparison between wood and also softwood pellets<br>
Timber pellets can be categorized right into wood pellets and softwood pellets



Wood consists of birch, poplar, yew, and elm. Wood have high thickness and also low water material, which burns longer than soft timber.



Softwood describes gymnosperm, such as ache, mahogany, cedar, and spruce. Softwood pellets melt more adequately than hardwood pellets.



Wood pellets can be utilized in home heating range, bbq, industrial boiler, and also power generation. The burning efficiency is greater than 80%, more than the coals' 60%. And also they generate much less SO2, NOx, ash and dust.



Comparison in between wood and also softwood pellets.

Rate

As hardwood cost higher than softwood, the rate of wood pellets is higher than softwood pellets. Hardwood pellets are usually offered as exceptional pellets.




Heat worth

Softwood pellets has higher calorific value than hardwood pellets, with 10% -20% BTU warm generation. This is since softwood pellets consists of more sap than hardwood and also makes them burn much faster.



Ash content

Ash content depend mainly on the cleanliness of sawdust instead of the timber types. Some researches compared the ash web content between softwood and also hardwood pellets. Although all premium quality wood pellets consist of lower than 1% ash web content, hardwood pellets may produce 3 times the ash of soft timber pellets. Provided a winter season duration, their differences are large.



Dirt emission

A research in 2009 examined the burning proportion and also dirt material of hardwood as well as softwood pellets. The result discloses that their burning proportion is similar, while their dirt exhaust differs a whole lot. For products with reduced burning proportion, the dust emission of softwood is higher than hardwood. For materials with high burning proportion, wood pellets has even more dirt exhaust than softwood pellets.



Benefits of wood pellets over wood logs

Sawdust are easy to acquire. They are much cheaper than wood logs.

The wood pellet making procedure consists of squashing, drying and also mixing, which will certainly boost the warm effectiveness as well as reduce the ash as well as smoke emission.

Timber pellets have moisture material less than 10%, while wood logs has 40-50% moisture. High wetness web content lower the warm and enhance the smoke as well as ash.

A ton of timber pellet gas burns a lot longer than a ton of wood logs, as well as create even more heat than logs.

Timber pellets have consistent size, form, as well as thickness, practical to store and also transport, and also apply in automatic burning system.

Should I select hardwood or softwood pellets?

To select hardwood pellets or softwood pellets, you must think about the following factors:



Your gas budget. As we understand, hardwood pellets cost more than softwood pellets. If you intend to spend less on gas, it is much better to choose softwood pellets.



Your burning ranges. Nowadays, the majority of timber pellet stoves adjust to both wood pellet and also softwood pellets. So you must contrast the top quality as well as performance of ranges, as opposed to hardwood or softwood.



Wood pellet production procedure. In fact, the quality of wood pellets is identified by exactly how it is produced as opposed to which timber it is made of.



Timber pellets are made by basic material crushing, drying out, molding and also air conditioning. The dimension of resources need to be 3-5mm, and also the dampness material need to be kept in between 14% and also 20%. Any of these procedure would certainly have excellent impact on the end product quality, but one of the most important variable is the pellet making machine. mini poultry feed machine can generate wood pellets with high density, smooth surface, high calorific value, and low ash content.
