Wood pellets are still occupying the highest grade biomass
fuel than biomass pellets fuel from other than wood. This is because its
combustion properties are better than others. But as the magnitude of the biomass
energy needs, it is necessary to look
for some other alternatives. Palm oil empty fruit bunch (EFB) is a potential
raw material for pellets. Currently, Indonesia is the biggest palm oil
producing country, especially crude palm oil (CPO) in the world with an area of
palm oil plantations of more than 7 million hectares and hundreds of palm oil
milss to process the palm oil fruits. Palm trees require warm temperatures,
sunshine and high rainfall, so that only some parts of the world can do that,
those are Asia, Africa and South America. Palm oil production is dominated by
Indonesia and Malaysia with an amount between 85-90% of world palm oil
production. Empty fruit bunches itself is a waste of CPO production which are
numerous and today generally untapped.
Another factor driving this is when the supply of raw
materials by planting some sort of energy plantation perceived longer and
require more capital, or when the availability of raw materials such as woody biomass
derived from wastes of the wood processing industries has been limited, the
empty fruit bunches of palm oil can be a strong candidate. While the other factor
come from the palm oil mill itself that many industries were overwhelmed to
handle empty fruit bunch waste itself. Those things are more encouraging empty
fruit bunch (EFB) processing into EFB pellets.
In terms of combustion properties as EFB pellet is lower
quality from wood pellets, so it should also be used technologies that are more
appropriate (suitable) in accordance with the character of the EFB pellets
product. Type of fluidized bed combustion technology is the best choice because
it is able to optimally handle EFB pellets at once able to reduce the content
of a number of negative traits. Chlorine is the most avoidable component of
mainly pellets made from agricultural wastes such as EFB. The fluidized bed
combustion technology has also been developed from along ago so that is
supposed to achieve optimum combustion conditions of EFB pellets become easy thing
to do.
