电站锅炉全负荷脱硝技术路线分析及选择

Analysis and Selection of Technical Routes for Power Plant Boiler Full Load Denitration Technology

以神华(福州)罗源湾工程项目的设计参数为基础,通过对当前常用的宽域脱硝技术路线的原理及改造后的效果进行对比分析,确定实现全工况脱硝的可行技术路线。提出对于新建项目可考虑采用能量补充方式的全负荷脱硝路线或给水加热方式的宽域脱硝路线,对于已投产机组采用分级省煤器方案的建议。

Based on the design parameters of Shenhua(Fuzhou) Luoyuan Bay project, through the comparative analysis of the current principle of the wide-area denitrification technology route and the effect of the transformation, the feasible technical route to achieve full-time denitrification technology is determined. It is proposed that a full-load denitrification technology route of energy supplementation or a wide-area denitrification technology route of feed water heating mode can be considered for new projects, and a proposal for a graded economizer scheme for the commissioned units is proposed..
