稻壳固定床气化炉的最佳参数研究

Optimum Parameters for Static Bed Rice Hull Gasifiers

用试验法在直径为16～30厘米的固定床稻壳气化炉上获得了最佳的气化强度,气化炉的净煤气效率在气化强度为100～200公斤/时·米~2时是提高的,在200公斤/时·米~2时达到最大值,本文提出了与气化炉横截面积无关的气化强度与净煤气的效率间的变化规律。

Optimum specific gasification rate is experimentally determined for fixed bed rice hull gasificr with its diameters ranging from 16 to 30cm. Cold gas efficiency increases with increase in specific gasification rate from 100 to 200 kg/ h . m2, and reaches maximum at 200 kg/ h.m2. An empirical relationship is derived between specific gasification rate independent of gasifier's sectional area and cold gas efficiency.
