摘要
对整体煤气化联合循环(IGCC)电厂NOx排放控制和系统效率提高进行了理论分析和计算,从热效率、技术风险、经济性等方面对氮气稀释方案和W+SCR方案进行了比较研究,得出了W+SCR方案为目前最为经济可靠的降低NOx排放的办法,且能提高系统效率的结论。
The NOx emission control and system efficiency increasing of IGCC power plant were analyzed and calculated theoretically. The nitrogen dilution process and W ＋ SCR proceess were compared in different aspects including thermal efficiency, technical risk and economical efficiency. The conclusion shows W ＋ SCR is the most economical and reliable method at the present time for reducing NOx emission, in addition to this, the system efficiency can also be raised by using W ＋ SCR method.
