PKS For CFB Powerplant
![]() |
49 MW Japan Biomass Powerplant Operates Since 2015 That Use PKS As Fuel |
With relatively low operating temperature ie 650-900 C then the ash problem can be minimized. Certain biomass fuels sometimes have high ash levels and ash chemicals that potentially damage these generating units. In addition, the fuel cleanliness factor is also very important, this is because technically certain impurities such as metal can close the air pores on the perforated plate of FBC unit, whereas air, especially oxygen is absolutely necessary in the combustion process and also the making the fuel bed in fluidized condition. The requirements for clean fuel must be met by the provider or seller of the biomass fuel, therefore the purchasers require an acceptable amount of impurities (contaminants), ranging from less than 1%. Cleaning of PKS is done by sifting (screening) either manual or mechanical machine, for more detail biomass fuel cleanliness problem can be read here.
In addition to PKS, pellet fuel from agricultural wastes or agro-waste pellets such as EFB pellets that have a high ash content and low melting point can also be used and not to worry for the fuel with this technology. Agro-waste production can be encouraged if there is a buyer, namely a biomass power plant with CFB technology. Although agricultural wastes are abundant in Indonesia but generally only burned or in pile only, because they are considered as a problem or pollutant. Why are these wastes not processed into pellets? One is because they have not found a market or buyers, although there is basically there's always a market for every type of pellet fuel. While the PKS that can be produced in Indonesia with the current palm oil plantations of 12 million hectares is estimated to reach 10 million tons / year, can be directly used for the power plant CFB. This is why the PKS is more sought after by current buyers.
The weakness of the CFB power plant is the high concentration of the flue gas so that the dust precipitator and the boiler cleaning system must be able to work efficiently. In addition the bed material is also lost with ash, so periodically need to be added again. Bed material commonly used is silica sand and dolomite. To reduce the cost of bed material usually reused after separated with ash. The technique is that the ash mixture is separated from a large size material with fine particles and silica sand in a water classifier. Next the fine material is returned to the bed. More specifically, CFBs are more efficient and less flue gas than BFBs so that boilers and flue gas cleaning systems can be designed to be smaller.
Biomass fuel gets a 4.3% share in Japan on their 2030 energy projections. This means that biomass accounted for 4.3% of 245 million MW per year with renewable energy or about 6,000 MW of biomass. To reduce CO2 emissions from coal Japan also make regulations on the efficiency of the coal power plants, to a minimum of 41% by 2030 while most of the current coal power plant efficiency is around 30-35%. Currently power plants that have an efficiency of more than 41% are only ultra supercritical pulverized coal. Modification of power plants can also be done to improve the efficiency, but certainly require more costs, so that the condition is increasingly becoming the driving force of biomass power generation especially CFB powerplant and the effect of increasing PKS demands.

Wood Pellet, PKS and Biomass Power Plant Market in Japan
PKS (Palm Kernel
Shell) to be a hot topic of renewable energy source or fuel commodity currently
in Japan. This is because PKS is the cheapest biomass fuel and is
currently still available in large quantities. PKS is a waste of palm
oil mill from CPO production. So it is automatically PKS is widely
available in areas of palm oil mill or CPO producers, namely in Indonesia,
Malaysia, and Thailand. Selection of PKS as fuel also its characteristics
that can be poured, high calorific value and high density also.
What about wood pellets? The world's leading producer of wood pellets
today, certainly not Indonesia or other Southeast Asian countries, but North
American and Scandinavian countries. Even for Indonesia itself wood
pellet is a new thing, so its production capacity also not big. Wood pellet price is more expensive than PKS. Most
wood pellets are produced in Indonesia from wood waste such as sawdust, wood
shaving, plywood waste and so on. The development potential for quantity
enlargement is also very possible with energy plantations. Technically
the properties of wood pellets are not much different from the PKS.

Biomass is one of
the alternatives fuel of power plants in
Japan, following the accident or destruction of the Fukushima nuclear power
plant (NPP) in 2011. PKS becomes
the favorite choice of biomass power plants there. Most of these biomass
power plants use PKS as their energy source, and only a few operate with wood
pellets. The large number of biomass power plants built, automatically
also requires a lot of fuel supply. Most of the biomass power plants are
built in 2015 and by 2017 some of them are in operation and by 2019 it is
estimated that they are all operating, so it can be imagined the need and
competition to get the supply of the PKS.
Japan is a
country that almost all rely on imports to meet domestic needs, this is because
the potential of the natural resources is minimum there, including the energy
sector. With a population of approximately half of Indonesia, their
energy consumption is almost 5 times Indonesia, so practical energy needs
including fuel is also huge. The biomass power plant that uses wood
pellets predicts that in the next 1 - 2 years there will be a shortage of supply
of PKS, so early on it has anticipated, although at present the advantage of
selling electricity is smaller, because of its more expensive raw material
(wood pellet) prices. With this experience they will confident if next
years wood pellets become more common fuel.
PKS must meet the
specifications before being exported to the destination country. Some
key specifications for PKS are: moisture content, calorific value and
impurities or contaminants (foreign materials). All three variables must
meet a certain level to achieve export quality. Japanese markets or their
consumers generally require contaminants from 0.5 to 2%, while European 2% - 3%.
A simple process can be done to get the quality of the PKS as above. Japan
usually buys with a volume of 10,000 tonnes per shipment or their import, so
for PKS providers must prepare a sufficient stockpile for the PKS. The
location of PKS stockpile that close to the seaport is the ideal condition to
facilitate transportation to shipment.
Wood pelletproduction process is more complex than PKS, so wood pellet is categorized as
finished product. PKS can be said raw product because of its industry
activity is very minimal and simple, as explained above. In the production
process of wood pellet will include selection of raw materials and the
properties namely : cleanliness, drought, size, shape and hardness. Based
on the characteristics of these raw materials, the next process varies until
become the wood pellet products. The wood pellet production process is
very much like the wood briquette. The quality of wood pellet is
generally viewed from its density, calorific value and ash content. Indonesia
wood pellet export is not as big as PKS, it is also because of the limited
producers of wood pellet itself. Japan buys wood pellets from Indonesia
mostly for testing on their biomass power plants. Shipping or export by
container is still common in wood pellet commodity because the volume is still
small.
For short-term
orientation exporting PKS is a profitable business. This PKS some time
ago only waste that contaminate and unworthy then large amount of it only used for
road hardening and so on, but currently become a “hot” commodity. Wood pellets with raw materials from energy plantations by planting the legume types such as calliandra are medium-term
solutions to meet biomass fuel needs in Japan. Torrefaction followed by densification can be
a long-term orientation, so the torrified pellets product is superior to wood
pellets because it can save transportation and facilitate handling, hydrophobic
and higher calorific value.
Government
Regulation namely Indonesian Minister of Finance Regulation No. 67/2010 on
Stipulation of Export Goods Subject to export duties (BK = Export Duties) have
purpose to push downstream or production of various derivative products from
oil palm including PKS. But the fact is not much that happened in the
field related to PKS. In fact, many PKS providers are experiencing setbacks and
even closed their businesses. This BK has made the price of PKS higher,
thus making the market demand decrease. The higher the BK for the raw
product and the lower the BK for the finished product the downstreaming will be
faster, but it must be done through the process gradually, well-planned and
comprehensive. Ideally the BK for the finished product is zero percent.
Does
the government ask people to wait next 2 years when PKS prices are
high because their needs are projected to rise sharply? We don't know. While the best scenario is to reduce taxes so that the industries can grow so then
they can start develop new products. Torrefaction of PKS becomes
torrified PKS becomes the best solution for next development, because upgrading
of PKS quality will give more economic value added. Carbonization or
pyrolysis of PKS to PKS charcoal (PKSC = palm kernel shell charcoal) and then
followed by densification into PKS charcoal pellets is also an attractive
alternative.

Looking Wood Pellet Market In Asia
![]() |
Global Energy Production by Source Source: EIA 2008 |
Areas that are able to produce wood pellets with low prices
would be a major exporter of wood pellets. Two components that are very
influential in the production of wood pellets is the price of raw materials to
factories and transportation costs to market. The position of Indonesia is
located in the Asian region with a tropical climate so the potential to becomethe largest producer of biomass has a strategic role of being a manufacturer of
wood pellets for the Asian market. Below are three major countries in Asia as
market for wood pellets:
South Korea Market
Development
Although South Korea is a small country, but a country 10th
in the world with the energy user fifth oil importer and second importer of
coal. Currently produces about 65% of the electrical of fossil fuels. South
Korea seriously to reduce greenhouse gas emissions to 30% reduction in CO2
emissions from 2010 levels by 2020. South Korea has also issued a RenewablePortfolio Standard (RPS) which requires a minimum power plant to use the 2% renewable
energy by 2012, with an increase of 0.5% / year until 2020. In 2020 they will
need a minimum of 10% renewable energy with the expected composition of 60% of
renewable energy derived from wood biomass, while the remaining 40% from other
sources.
Japanese Market
Development
Japan has almost no natural resources, so that imports
nearly all of almost all the coal, oil and gas. Japan is the largest importer
of natural gas and petroleum ranked second in the world. Since the accident or
the explosion of Fukushima nuclear power plant in 2011, the Japanese government
review of national energy policy and resource development. The policy indicates
that for the next 10 to 20 years for renewable energy, the increased use of
non-fossil energy to 50% and greenhouse gas reductions in electricity
generation from 34% to 70% in 2030.
China Market
Development
China is currently the second largest energy user after the
United States. Energy is the foundation of economic growth in China. Coal is
the main energy in China that make this country the largest user of coal in the
world. Although very little renewable energy policy announced by the Chinese
government, China in its five-year plan to allocate $ 750 million in direct
subsidies, incentives and tax exemptions for building 200 green energy
demonstration project in 2015 or at least 15% of its energy needs from
renewable energy. China has also set up a biomass energy production with a
target of 50 million tonnes of coal equivalent by 2012. Although the 5-year
plan does not indicate specific green energy projects to be addressed, a number
of assumptions stated China will produce wood pellets to replace coal. The
majority of the production of wood pellets also comes from domestic production
so that its import was minimal.

Racing for Lowering The Temperature Of The Earth
Although the carbon neutral scenario
does not reduce greenhouse gas concentrations in the atmosphere, but with this
scenario does not add more greenhouse gases in the atmosphere. The use of carbon
neutral fuel from biomass is the concrete step. Gradually the role of the biomass fuel usage is improved
and strengthened with the support by the state regulations. A number of
countries have dared to take an ambitious policy for the utilization of biomass
in the massive scale. Confidence factor such as the solution to the
environmental problems of climate change and global warming, depletion of
fossil fuel reserves, the image of an environment friendly country that will be
known the world , and the economy are driving some of those countries to
implement the policy.
For Asia, South Korea has started
using biomass massively with the officially issued the Renewable Portofolio Standard (RPS) in Korea in 2012. The regulation state that 2% of the
electricity shall come from renewable energy. Percentage of renewable energy
needs will increase in incremental reach 10% in 2022. Another driving force is
the emissions trading scheme which will be issued in January 2015. Whereas in
Japan the energy strategy to be the hit of nuclear reactors has since abandoned
some time ago. The actual strategy including the manufacture of power plants
with the composition of nuclear and renewable energy from 30% to 70% until
2030. Japan with a population about half the residents of Indonesia but its
energy consumption 5 times in Indonesia. Japan is also targeting production of
energy from biomass power plants with a capacity of 1100 MW until 2020. As for
the use of renewable energy have a target to reduce Japan's emissions of CO2 by
1990 levels by 2030. While China has a goal to use the 11.4% from non-fossil
fuels from primary energy consumption in 2015. Its CO2 emissions will be
reduced by as much as 17%. The Target reduction of CO2 emissions by as much as
40-45% by 2020 to reach such a level in 2005. In Europe, with a target of
20-20-20 has prompted demand especially for biomass pellets fuel. Target
20-20-20 is a greenhouse gas reduction of 20%, 20% renewable energy use and
energy efficiency at 20%. Effective tool in Europe to achieve the targets is
the emissions trading scheme (emission trading scheme EU ETS/).
Indonesia has also announced to
reduce fossil energy by 2025, with the share of fossil fuels 83% and renewable
energy around 17% in particular biomass gets a share of less than 5%. The
energy potential of biomass in Indonesia is huge i.e. equivalent electric 49,810
MW but in utilized is still less than 4% or equivalent of 1,680.4 MW. Critical
land and unused land that reach millions hectares, become an extraordinary
potential to provide energy plantations to produce biomass as an energy source.
Optimisation of the potency will support the target achievement the energy
consumption of biomass as renewable energy in total energy mix. . Finally the
creation of a low-carbon economy can be a solution for the welfare of society
and improve the quality of the environment, with the most popular commodities
i.e. wood pellets. The Global market for these pellets predicted to rise from
16 million tons (2010) becomes 47 million tons in 2020.
