摘要

在自制的小型常压流化床内采用多孔介质床料对生物质颗粒燃料进行气化试验

分别考察了富氧气氛下温度和氧气浓度、水蒸气气氛下温度和水蒸气流量及不同种类多孔床料对生物质颗粒燃料气化的产气成分及产气热值的影响。试验结果表明:随气化温度的升高

产气中H2含量增加

CH4含量降低

产气热值降低;氧气浓度对气化有一定影响

在试验条件下

增大氧气浓度可以提高产气中H2含量;随着水蒸气流量的增加

产气中H2含量从11.89%增加到45.77%

但产气热值降低;在3种不同的多孔介质床料中

以沸石为床料时气化产H2效果最好。

Abstract

The gasification test of adopting petterized biomass fuel as porous media has been carried out on a self-made small atomospheric pressure fluidized bed

investigating the effects of various factors

such as gasification temperiture and oxygen concentration(under rich oxygen atomosphere)

gasification temperature and steam flow rate(under steam atomosphere)

as well as different kinds of bed media upon the composition and calorific value of produced gas respectively.Results of test show that the H2 content has increased

the CH4 content having dereased

and the calorific value of produced gas being decreased along with the gasification temperature rise;the oxygen concentration has certain effects on gasification;the H2 content in produced gas can be increased by heightening the oxygen concentration;along with the increase of steam flow rate

the H2 content in produced gas has been increased from 11.89% to 45.77%

however

the calorific value of produced gas being decreased.In three kinds of different bed media

taking zeolite as bed medium has the best effect of H2 production.
