摘要

对超临界600MW机组锅炉在脱硝改造中增设引风机的选型进行了分析

通过对分设与合并引风机和脱硫增压风机

以及引风机采用动叶可调、静叶可调及变频静叶可调几种方案的经济性进行比较

认为采用变频静叶可调轴流式风机

且引风机和脱硫增压风机分设的方案最为经济。

Abstract

The type selection of added induced draft fans(IDF) during nitrification retrofitting of a supercritical 600 MW unit boiler was discussed.The economic efficiency of different schemes such as separating or merging the IDFs and desulfurization booster fans

the IDFs with adjustable dynamic blades or stationary baldes or with variable frequency and adjustable stationary blades

were compared.Results showed that

the scheme which using variable frequency axial flow fans with adjustable stationary blades and separately locating the IDFs and desulfurization booster fans is the most economic way.
