hi frnd..
1st offall ur question is wrong..
actually suction of ID fan is in negative..
in boiler furnce draught maintain (-3mmwc to -5mmwc) with
the help of ID fan.ie it's create vaccum in boiler side..
and it's discharge goes to stack which is positive..

Answer / ab
At normal condition ID fan discharge pressure is at 0-25mmWC. But due to chimney stack effect ID fan discharge pressure may be slightly negative

ID Fan develop the suction from boiler furnace so it shows
negetive pressure.
| Is This Answer Correct ? | 11 Yes | 8 No |
bcz this fan is inducing draft fan this is suctioning the
draft

pressure always flow from high to low pressure .
furnace pressure is high and atmospheric pressure is low
when the damper is opened automatically all the pressure to
the low pressure. the low pressure in the sense it is vaccum
only and negative is only vaccum
