Physical and combustion properties of torrefied empty fruit bunch after densification

Increasing demand of energy, depletion of the fossil fuel reserves and increasing in air pollution have increased interest in biomass especially on palm biomass as a renewable energy sources. However, untreated palm biomass which is empty fruit bunches, EFB has a couple shortcomings such as high moi...
