Process simulation of co-firing torrefied biomass in a 220MWe coal-fired power plant.

Highlights: [•] The performances of torrefaction based co-firing power plant are simulated by using Aspen Plus. [•] Mass loss properties and released gaseous components have been studied during biomass torrefaction processes. [•] Mole fractions of CO2 and CO account for 69–91% and 4–27% in total torrefied gases. [•] The electrical efficiency reduced when increasing either torrefaction temperature or substitution ratio of biomass. [Copyright &y& Elsevier]
