Abstract:

After the ultralow emission transformation, there is frequent stalling on adjustable axial flow induced draft fan of a 1000MW unit. According to the body, design parameters and pipe network matching of the fan, the cause of fan stalling is analyzed and the prevention for the stalling of the induced draft fan after ultralow emission transformation are proposed.
