摘要
Abstract
In order to enhance the adaptability of the forced draft fan under deep peak shaving of a certain 350 MW supercritical unit and optimize the oxygen regulation capacity of the boiler operation under low-load conditions,the forced draft fan is subjected to speed reduction and optimization transformation.It carries out relevant tests on the actual performance of the forced draft fan after its renovation,and based on the test data and results,it analyzes and studies the effect of this forced draft fan renovation.The results show that the output margin of the forced draft fan after the transformation can meet the operation requirements of the full-load section of the unit.The operating points of the fans under different loads are far from the stall line,and there is no risk of stall.The regulation capacity of the boiler flue gas system operation under deep peak shaving is enhanced.It increases the efficiency of the fan,decreases the power consumption rate of the plant,and improves the operational economy.关键词
