One of Denmark power station information provide by clients, they using 5MW Biomass fired cfb steam boilers , which using co-firing biomass to heating cfb steam boilers for power station.
1.Biomass co-firing in modern power plants with efficiencies up to 45 % is the most cost-effective biomass use for power generation.
2.In the case of co-combustion of up to 5% energy of biomass only minor changes in the fuel handling equipment are needed and the steam boiler output is not noticeably derated.
3.For biomass exceeding ~10% share changes in mills, burners and dryers are needed.
4.If not carefully designed, firing biomass fuels in an existing coal fired power plant involves risks of increased plant outages and possible interference in plant operation due to the differences in combustion characteristics of coal and biomass.
5.These are all manageable but that they require careful consideration of fuels, steam boiler operating conditions, and steam boiler design.
There is a long experience of co-firing at 5 MW Studstrup Power Station:
1.The use of a separate straw feeding system is essential to warrant successful straw-coal co-firing.
2.After the straw bales are processed the pulverized straw is fed pneumatically onward and fired through the centre-pipe of the coal burners.
3.The maximum straw capacity at full steam boiler load is 20 ton/h which corresponds to a straw share of 10% on energy basis
