How To Make Quality Pellets?

There are various raw materials available for homemade flat pellet press. However, the presence of excessive levels of chlorine in the biomass fuel may lead to the severe metal corrosion of the flat pellet press. This can be reduced by using additives, similar to the process utilized in the coal industry. Overall, it is recommended that potassium and chlorine levels not exceed 0.2 percent and 0.1 percent, respectively, for biomass materials used in power generation.

By changing the time of harvest it is possible to reduce levels of water-soluble chemicals in the raw material to enhance the fuel value of pellets produced by homemade flat pellet press. The chlorine and potassium content of a number of grass species is reduced by harvesting late in the season or after winter has passed. So if you want to make quality grass pellets with your flat pellet press, you can harvest the grass after winter. The same occurs to leached straw, thereby converting yellow to gray straw to reduce the content of water-soluble potassium and chlorine.

With high quality raw material, your homemade flat pellet press can produce fuel pellets with low levels of potassium, chlorine, sodium and sulfur, as these elements lead to particulate emissions during combustion. Besides flat pellet press, there are several factors ultimately determine the amount present in the feed, some of which can be controlled. These include: fertilization practices, choice of species, stem thickness, time of harvest and regional precipitation. Biomass-fuelled boilers are typically designed for wood, which is lower in ash and chlorine levels. However, new multi-fuel boilers are being developed and are becoming more widespread. These can burn agricultural and wood biomass more and more effectively. One of the keys to make your homemade flat pellet press perform at its peak is a good planning stage, in understanding the needs of end-users, and if these needs are compatible with available raw materials for the prospective operation.
