摘要

采用循环流化床气化中试装置对玉米秸秆进行了气化试验,分别在常温空气与250℃预热空气条件下,研究了空气当量比(ER)和原料含水率对气化特性的影响规律。结果表明:随着ER的增大,循环流化床气化炉内的反应温度升高,气化燃气中的CO2含量增加,焦油与CO含量及燃气热值降低,气化效率随ER的增大呈先增大后减小的趋势;随着气化原料含水率的增加,循环流化床气化炉内的平均温度下降,燃气中的CO2与H2及焦油含量逐渐升高,CO含量下降,CH4与CnHm含量均为先增加后减少。与常温空气工况相比,预热空气工况下的燃气热值与气化效率均有一定程度的提高。采用预热空气为气化介质,提高气化剂温度,可显著促进玉米秸秆的气化反应,提升气化效率。

Abstract

A circulating fluidized bed gasification pilot plant was built to study the effect of air equivalence ratio (ER) and water content of corn straw on gasification characteristics under conditions of using normal temperature air and preheated air at 250oC as gasifying agent respectively. The results showed that the gasification temperature and CO2 content in the fluidized bed gradually increased with the increase of ER, while the calorific value and tar content both decreased. The gasification efficiency increased first and then decreased. The average reaction temperature in the gasification furnace and CO content decreased with the increase of raw material moisture content, while the content of H2, CO2 and tar in gas increased. The content of CH4 and CnHm increased first and then decreased. The calorific value and gasification efficiency under preheated air were higher than that under normal temperature air. Using preheated air as gasifying agent and increasing the agent temperature could significantly accelerate the gasification reaction and improve the gasification efficiency.
