含水性对秸秆气化特性影响的实验研究
|
摘要
本文主要研究了当量比为0.28的纯氧气氛卧式管式炉中温度及含水性对秸秆气化特性的影响。研究发现,温度的升高有利于加快产物气的释放,同时可以提高CH_4的释放量。水蒸气对生物质的气化过程有着不可忽视的影响,含水的秸秆可以释放出更多的CH_4和CO_2,但是CO的释放比例有所下降。
In this paper,the effects of temperature and water vapor in the horizontal tube furnace were studied,which was focused on the gasification characteristics of straw with pure oxygen at the equivalent ratio of 0.28.It was found that the increase in temperature was conducive to accelerate the release of product gas and could increase the release of CH_4.Water vapor had a significant effect on the biomass gasification process and the watery straw could release more CH_4 and CO_2,but the release ratio of CO had declined.
