Co-firing biomass with coal is widely considered as one of the most cost-efficient and easily deployed way for mitigating the CO2 emissions from coal-fired power plants

which has been widely used in Europe and America. However

biomass co-firing in China is limited to demonstration levels. It is positive to make a systematically research and learn from the successful experience of Europe and America in promoting the application of biomass co-firing. This paper shows the technology roadmap

development status and various technical and non-technical issues associated with biomass co-firing. Finally

the development prospect of biomass co-firing in China is also discussed. The results are as follows. Direct co-firing is the main application technology because of simplicity

high efficiency and low cost

but direct co-firing may have some technical problems

such as incomplete combustion

deposition and corrosion

performance degradation of flue gas treatment equipment

etc. The measures to prevent risks include choosing appropriate co-firing ratio

pretreat the fuel

etc. However

there are some non-technical issues on the popularization and application of biomass co-firing in China

such as imperfect biomass fuel market

insufficient policy support and lack of technical specifications.
