We have a pollution system.There are heat exchager and bag filters and by knowing the temperature of heat exchager inlet/outlet and bag filter inlet/outlet how can I calculate the delta T. Before that please tell me what is Delta T

You may be looking for LMTD (logarithmic mean temperature difference) instead of ΔT (which means temperature change). There are various ways to express this; probably there is a good Wikipedia article on it.

Give a better explanation of your system so we know what you want.

Temperature rise across a centrifugal fan at sea level is about 1/2 degree F per inch of water static pressure.

Does the heat exchanger preheat/precool makeup air? What does it do?
