Biomass particles, also known as wood chips, mainly in wood processing and wood-based panel production of sawdust, shavings, bark, sanding powder, waste wood, branch material; crop harvest after the various types of straw; The combustion of biomass is made from raw materials for combustion, barbecue and fireplace heating. The combustion efficiency is over 80% (more than 60% of the efficiency of conventional coal combustion). The combustion efficiency is high, resulting in sulfur dioxide, ammonia nitrogen and dust Less, then, choose the wood chip particles which need to pay attention to it? Xiao Bian finishing six points:
Strict water requirements
The moisture content of the raw material of the wood chips is strict. No matter what kind of wood chips, the moisture content must be kept within a range (preferably 14% -20%), too dry, and the water is large and loose.
The adhesion of the material itself
The raw material itself must have the adhesive force.If there is no, then the wood pellet machine extruded products either do not form, or loose easily broken.Therefore, if you see the material is not adhesive itself can be compressed into particles or blocks, that raw materials Sure to move hands and feet, or be fermented or added a binder and the like.
Add adhesive
The use of pure wood chips can be, do not need to add other adhesives, because the sawdust is a crude fiber raw materials, itself has a certain degree of adhesion.After the compression of the wood chips machine, naturally can be formed, and from the The pressure of the pellet is very large.
Can different types of wood chips be doping?
It is made of pure wood chips and can not be doping with other varieties of wood chips. All kinds of wood chips, wood shavings, mahogany, poplar can be, furniture factory waste can also be. More broadly, like crops Straw, peanut shells, these things can be used as wood pellet machine raw materials, of course, made out of the particles can not be called wood chips, but straw particles.
The size of the raw material after crushing
Sawdust, branches and other raw materials must be crushed to crush the granulation, crushing the size of the particle size according to the expected size of the particles and particle size of the mold to determine the size of the crushed too large will affect the output, or even cause no material.
Raw mold mildew how to do?
The raw material is mildew, the color becomes black, the cellulose in the wood chips is decomposed by the microorganism, can not be pressed into qualified particles.If you can not use, it is recommended to add more than 50% fresh wood raw materials mixed use, otherwise can not be pressed into qualified particles The
