How much Vacuum can be expected to be produced if a Boiler that operates at 2600psig drum and at Saturation temp. is allowed to depressurize with fires out and no venting to atmosphere when cooling. there is a transition from pressure to no pressure approx. 212Deg. of course. My question is what will the pressure be at lets say 180Deg.f

Its the saturation pressure at 180 degrees or whatever temp you chose; and 212 degrees has no significance since it is a closed system. You can look it up in steam tables. If you can't find them, I will look for mine and answer.
