The paper presents the tripping of air induction steam turbines of Primary reformer in Fudao second stage ammonia plant,analyzes the reasons for steam turbines tripping during overhaul,puts forward relative countermeasures,which have achieved good results.

Discussion on integration modes of induced draft fans and booster fans;

Application of Frequency conversion in induced draft fan and energy saving analysis;

Energy saving efficiency comparing before and after using frequency control of electric-machine speed for boiler induced draft fan in Shaoguan power plant;

Improvement of power-saving on high-volt VFD for processing kiln fan;

Application of Inverter and Electric Saving Setting in Boiler Fan Energy-saving;

We havefound good process of repairing techniques use d in repairing the axes of blower and s ome typical aspects needed for special cares.

Retrofits of the Regulating Wind Doors at the Inlets of AYX75-INO22D Type Draught Fans;

In view of the fact that the wear and tear of the vane of the draught fan wear quicker and the expenses of maintenance is expensive.

Several methods of adjusting draught fan in thermal power station are introduced in this paper.
