摘要:

分析了独立焦化厂开工备用锅炉系统的配置及节能环保方面问题。分析得出,开工锅炉首选燃用天然气或焦炉煤气,备用锅炉首选燃用焦炉煤气;锅炉容量应优先考虑选用2种参数的锅炉;锅炉系统优先考虑低位除氧器的布置方案;宜利用焦炉烟气脱硫脱硝系统对锅炉烟气进行处理。

Abstract:

Analysis is made to configuration of standby boiler system during start-up of independent coking plant and to the energy saving and environmental issues.The result shows that natural gas or COG is the first priority to use for main boiler start-up,and COG is the first priority for standby boiler.Boiler with two kinds of parameters shall be taken for preference for volume selection.Low-position deaerator shall enjoy priority for boiler system arrangement.DeNOx and DeSOx systems should be used for treatment of emission from the boiler.
