Experimental Studies of Torrefied Biomass Co-Firing with Coal in Drop Tube Furnace

E.M. Gucho, E.A. Bramer & G. Brem
Co-firing of biomass with coal in traditional coal-fired power plants represents is a low-cost option for a fast introduction of renewable energy on a large scale. However there are some technical issues associated with biomass co-firing such as fuel flexibility of the plant, combustion efficiency impacts on the ash marketing, fouling of the boilers, etc. The combustion efficiency is highly affected by the physical combustion properties of the biomass and coal, and the residence time...
