Coal Co-firing with Hydrothermally-Treated Empty Fruit Bunch Using Computational Fluid Dynamics

Coal Co-firing with Hydrothermally-Treated Empty Fruit Bunch Using Computational Fluid Dynamics

Biomass co-firing into the existing pulverized coal boilers has economic and environmental advantages, such as reduced slagging inside the furnace and lower GHG emissions. Compared to other pre-treatments, hydrothermal treatment has high conversion efficiency, capability to eliminate the energy-inte...
