摘要

针对W火焰锅炉的高NOx排放与单一采用低NOx燃烧技术很难使之达到环保标准的矛盾

提出了低NOx燃烧与SNCR技术联合应用方案。用国外先进商业软件CFX-TASCFLOW对某电厂300 MW机组W火焰锅炉采用低NOx燃烧与SNCR技术联合应用进行了数值模拟

重点对不同优化燃烧模式下适合于SNCR温度窗口的关键技术参数进行了准确的计算分析。通过模拟可对选择适合于与SNCR联合应用的低NOx燃烧方式

以及在合适的低NOx技术下选择合理的温度窗口位置加设SNCR

保证联合应用技术的有效性提供指导。

Abstract

Directing against contradiction between the high NOx emission and the difficulty in achievement of environment protection under condition of applying only the single low NOx combustion technology onto the W-shaped flame boiler

a scheme of combined application of low NOx combustion and SNCR technology has been put forward.By using advanced commercial software CFX-TASCFLOW imported from abroad

a numerical simulation of said combined application on the W-shaped flame boilers of 300 MW unit in one power plant has been carried out

the key parameters suitable for temperature windows of SCNR being precisely calculated and analysed under different optimized combustion modes.Through simulation

the low NOx combustion mode suitable for combined application with SCNR has been selected

and the suitable locations of temperature windows being determined for additionally installing SNCR under suitable low NOx combustion mode

providing guidance for ensuring effectiveness of the combined application technology.
