煤颗粒流化床脱挥发份的实验研究

An Experimental Study of the Devolatilization of a Coal Particle Fluidized Bed

在一小型流化床实验台上，进行煤颗粒的脱挥发份实验，研究了床层温度、煤种、气氛等因素对煤中Ｃ、Ｈ、Ｎ元素在脱挥发份过程中变化行为的影响。

A devolatilization test of coal particles was conducted on a small sized fluidized bed test rig.Studied is the effect of bed layer temperature,coal type,ambient atmosphere and other factors on the changing behavior of such elements as C,H and N in the coal in the course of devolatilization.
