燃煤锅炉脱硝技术的应用

Application of denitration technology in coal fired boiler

为了保证氮氧化物排放限值的实现,践行企业领先的环保理念,必须对循环流化床所产生的烟气进行深度脱硝。我公司选用SNCR-SCR联合脱硝,是一种高效脱硝的新技术,其核心是基于不同脱硝耦合的综合脱硝技术,是我国对现有脱硝工艺探索发展的一个方向。与单独脱硝工艺相比,在同一个系统内同时实现脱硫和脱硝,具有低成本、高效能的现实意义。该技术在我公司成功应用标志着SNCR-SCR联合脱硝技术具有成熟性、可靠性及经济性。

In order to ensure the realization of NO x emission limit and implement the enterprise's leading environmental protection concept,it is necessary to conduct deep denitration on flue gas generated by circulating fluidized bed.SNCR-SCR combined denitration is a new high-efficiency denitration technology.Its core is the comprehen sive denitration technology based on different denitration coupling,which is a direction of exploring and developing the existing denitration process in China.Compared with the single denitration process,simultaneous desulfurization and denitrification in the same system has practical significance of low cost and high efficiency.The successful application of this technology in our company marks the maturity,reliability and economy of sncr-scr combined denitrification technology.
