ID fan(Induced Draft Fan)basically pulls out flue gas from
the furnace of boiler. It is located between dust
precipitators(ESPs) and Chimney. Obviously it handles hot
air/dust. Whereas, FD fan(Forced Draft Fan)supplies the
required air into the furnace for combustion of fuel. It
handles air at normal temperature. The capacity/power
rating of ID fan will be more than that of FD fan

Where is servomechanism used?
I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
