As a source of energy or wood pellet fuel or pellet fuel can
be used in small-scale such as the household to large-scale on power plants.
Both quantity and quality pellet are the parameters in its use in relation to
equipment that is used. Basically from small-scale to large scale on the use
pellet fuel especially related to efficiency factor, easy in operation, safety and
gas emission impact (eventhough wood pellet include as renewable fuel that
enter the category as carbon neutral) while the use on large-scale the qualityfactor of pellet got a serious attention. Technology that was used to utilize
the wood pellet is almost all use combustion technology (direct combustion) to
get output in form of heat or electricity.
In small-scale the use pellet fuel for mainly in the four
season countries for room/space heating, even for this sector needs premium
quality of wood pellet for pellet stove. Pellet stove has not yet been familiar
in Indonesia because the wood pellet also still very difficult to get. Other
equipment that are to be used in small-scale is boiler and burner. Boiler
system will produce steam to source of steam and hot water. While burner can be
used for various source of heat.
On the medium-large scale, users mainly for industries and coal-fired
power plants. Grate combustor and stoker are equipments that general used in
the industry. Pulverized technology system and fluidized bed commonly used in
power plant. The percentage of wood pellets this time is still less than 5
percent on the use of cofiring in the coal powerplant. Wood pellet for pulverized
while biomass pellet for fluidized bed. The characteristics of both pellet cause
of the difference.
