Do these also work in an "OPEN" system, outdoor wood boiler install?

They do, although their efficiency will be decreased due to a continuous supply of oxygen-rich water. Air eliminators (unlike air vents and air scoops) are mainly designed to eliminate small bubbles from the system which cause corrosion of iron components. While they will vent out a lot of air even in an "open" system, they are more effective in "closed".
