固定层间歇生产造气炉吹风量分析

Analysis of blow-air amount for fixed bed gasifier

通过对固定层造气炉在吹风阶段建立吹风氧化层高温区和吹风过渡层高温区的基本机理的分析 ,揭示出造气炉内气化层固相和气相温度的分布特点以及各层面对气化反应强弱、炭消耗指标高低的影响。提出了造气炉吹风量应达到使固相蓄最大量热于炉内、气相只移最少量热于炉外的定性要求和定量准则。

Through analysis of basic principle and process forming high temperature zone in oxidizing layer and intermediate layer in phase of blowing air in fixed bed gasifier,it is revealed the features of temperature in gasifing layer and their effect on reaction and coke consumption.The suitable ammout of blow-air is proposed by storing maxmum heat in gasifier with solid coal and releasing minimam heat out of gasifier.
