600MW电站锅炉SCR脱硝系统全负荷投运改造方案研究与工程实践
Research on Transformation Scheme for Full-load Operation of SCR Denitration System of 600 MW Substation Boiler and Engineering Practice
摘要
Abstract
In allusion to the status quo of selective catalytic reduction (SCR) denitration system being unable to be in opera‐tion with low load in one 600 MW coal‐fired power plant ,this paper introduces three transformation schemes for full‐load operation of the SCR system .Thermodynamic calculation for the boiler and comparison of schemes indicates that the opti‐mal scheme is to use economizer classification and then field transformation is finished .In two aspects of entrance fuel gas temperature of SCR and boiler efficiency ,it analyzes effects after transformation which indicates preferable engineering effects of classification transformation of the economizer .关键词
