Size reduction of biomass is a very important process to break down the lignin content of biomass and increases the total surface area leading to greater inter-particle bonding [30,31].
During biomass particle combus- tion, the results showed that the surface tension on the biomass char particle plays a signiﬁcant role due to partial melting of the char particle.

IntroductionNumerous epidemiological studies have shown a correlation between negative health effects and increased concentrations of particulate matter in the ambient air (e.g., ).Because of this correlation and the increasing use of biomass combustion, the particle emission from biomass combustion, particularly that of ultrafine particles, needs further investigation.
The development of the fluidized bed gasifier (FBG) for small particle materials has made great progress for biomass gasification. The productivity of the FBG has increased by five times that of the fixed bed gasifier and the heating value of gas increases by about 20%  .

Conventional biomass pellet production (Fig. 12.4) includes an initial size reduction to a 2-in. particle, followed by drying to 1012% moisture content (wet basis) using a rotary drier. The dried biomass is then passed through a second-stage grinding process to reduce the particle size to less than 3/16-in., steam conditioned, and pelletized ( Tumuluru et al., 2010, 2011; Tumuluru, 2014 ).
