CFB锅炉飞灰含碳量影响因素分析
Influence factors of carbon content in fly ash in circulating fluidized bed boiler
摘要
Abstract
Taking a 300 MW unit circulating fluidized bed (CFB)boiler as an example,the influencing factor coefficient analysis method was employed to investigate the effects of several operation parameters on car-bon content of fly ash under conditions with different loads and variable load,such as the coal particle size, the pressure ratio of the secondary air outlet pressure to pressure drop in dense phase zone,the oxygen con-tent at the economizer outlet,the ratio of the primary air volume to the secondary air volume,and the bed temperature.The results show that,the ratio of the secondary air outlet pressure to pressure drop in dense phase zone,and the ratio of the primary air volume to the secondary air volume,have greater influence on the carbon content of the fly ash.While the oxygen content at the economizer outlet and the bed tempera-ture (880~930 ℃)have relatively lower one.The results of this study provide guidance for the adjustment of combustion underpants leg type circulating fluidized bed boiler.关键词
