When density of precipitated slurry is too high, because of the collision among particles, big spindly aggregates which are made of ultra-fines are born in reactor at the action of surface energy.
当体系中浆液密度较高时，颗粒由于相互间的碰撞在表面能的作用下团聚成纺锤形的大颗粒。

Due to its low energy density and high oxygen content, biomass is often pretreated by slow pyrolysis to form semi-char which is then fed to the entrained flow gasification reactor.
The reactor features simple and compact structure, little energy consumption, high clearance, low processing cost, moderate processing condition, and easy realization of industrialization.
