Wood pellets are low
-cost biomass and can also be considered as renewable fuel (Gori
et al., 2013), which is an attractive source of energy for largescale
biomass combustion plants (Hossain et al., 2016). Wood pellets
combustion is a new technology due to fuel scarcity and
environmental concerns over burning fossil fuels (Zhang et al.,
2009), and they have good potential for providing thermal energy
in the industry or electricity generation.
