“Biomass co-firing in modern, largescale coal power plants is efficient, cost-effective and requires moderate additional investment.
In general, combustion efficiency of biomass can be 10 percentage points lower than for coal at the same installation, but co-firing efficiency in large-scale coal plants (35%-45%) is higher than the efficiency of biomass-dedicated plants.
In the case of cocombustion of up to 5%-10% of biomass (in energy terms) only minor changes in the handling equipment are needed and the boiler is not noticeably derated.
For biomass exceeding 10% or if biomass and coal are burned separately, then changes in mills, burners and dryers are needed. In addition, coal ashes that are used to produce construction materials should not be contaminated with tar and alkali metals-rich ash from biomass.”

(Danish Briquettingmachine manufacture)
� Conclusions on Indonesian market according to CF Nielsen.
� Should focus on local market use
� Eksport to Europa is very difficult due to logitics prices and the Europena market will only by wood based briquettes
� No power plants are interrested unless price is much lower than other biomass
Investment in Briquetting machinery
(C.F. Nielsen)
� For consumer briquettes � Investment: 200.000 - 300.000 €� Capacity: 1.000 - 1.400 kg /h . � Direct costs such as electricty, spare parts, service and maintenance
( ~ 15 EUR per ton)
� For industrial briquettes � Investment: 100.000 og 200.000 €� Capacity: 500 kg - 1.800 kg /h. � Direct costs such as electricty, spare parts, service and maintenance

CoCoCoCo----firingfiringfiringfiring
Three state–of–the–art systems:
Direct Co–firing systems, combustion of both fuels takes place within the same boiler, thus mixing coal and biomass ashes.
Parallel system, biomass and coal are burned in separate boilers with physically independent feeding and ash removal systems.
Indirect system, fossil fuel is burned with previously gasified biomass and, hence, coal and biomass ashes are also removed in different parts of the processes.
Ash removal is one the most important constraints for increasing the share of biomass in Co–firing systems. Ash melting temperatures of many biomass sources are normally lower than coal due to their high alkali metal, calcium or iron content. This feature may cause several problems such as slagging and fouling in the burners, furnace walls or superheaters.
Other problems that may arise are related to the different grindability of biomass and coal, or the diverse combustion behavior of both fuels.
Direct Co–firing is by far the most implemented configuration in European coal–fired power plants, accounting (more than 150 plants with total electrical and thermal capacities of 35 GWel and 22 GWth).
In Direct systems, the maximum share of biomass in the fuel blend is less than 5 –10 wt% (3 – 6% on energy basis). Higher ratios would imply boilers modification with the inherent increase in capital investment.
Danish Energy
� The government’s long-term vision is that Denmark will become independent of fossil fuels by 2050 while reducing greenhouse gases by 80–95% compared to 1990. This will require a total conversion of the Danish energy system, away from oil, coal, and gas, which today account for more than 80% of energy consumption, to green energy, with wind turbines and bioenergy as the most important elements.
� The European Union presently has a goal of reducing GHG emissions by 20% by 2020 from the 1990 level. Denmark is urging the EU to adopt an even stricter goal of 30%
� Danish coal power plants are already remarkably efficient. Any coal plant makes just two things: electricity and heat. Most coal plants use only the electricity, sending the heat up the chimney as waste. Thus, most coal power plants are only about 30% fuel efficient.
� In Danish power plants, both electricity and heat are used (known as combined heat and power, CHP). The heat is captured and used to heat hot water, which is pumped through a vast network of super-insulated pipes to heat homes throughout the country (called district heating). Denmark’s best power plants are more than 90% fuel efficient. Today, more than 70% of Denmark’s homes are heated by district heating.

Avedøre Power Station
Danish Power plant Avedøre
Dong Energy’s Avedøre Power Station near Copenhagen, which provides electricity
for 1.3 million homes in northern Europe and district heating for 200,000 homes in
Greater Copenhagen. Total electricity production is 825 MW and heat production is
575 MJ (megaJoules). The facility has two units.
Unit 1 is coal- and oil-fired.
Unit 2 uses several types of fuel, including natural gas, oil, and biofuels (straw and
wood pellets). It is one of the world’s most efficient CHP facilities, using up to 94%
of the energy in the fuel. The two 55-MW gas turbines operate as peak load facilities
when electricity and heat demand are high. The plant consumes 600,000 tonnes/year
of wood pellets.
Denmark presently imports 85% of its annual wood pellet consumption. This figure will
increase as the country implements it coal reduction plans.

Amager Power StationAmager Power StationAmager Power StationAmager Power Station
Amager Power Station (Vattenfall) near Copenhagen, which has a total electricity capacity of
438 MW and thermal power capacity of 747 MW, which corresponds to the heating required by
about 115,000 households.
It has three units.
The station burns about 700,000 tonnes/year of coal. Oil is used only for start-up, and
consumption is slightly more than 3,000 tonnes/year.
The station also burns about 150,000 tonnes/year of biomass in the form of straw pellets.
