Narrative:
Chicago ARTCC gave us a crossing restr 'cross 90 mi southwest of ord at FL240.' we had anti-ice on and could not bring the power all the way back and still heat the wings. We brought the power back as far as we could and still have anti-ice working and pulled the speed brake. We missed the crossing by approximately 800 ft. This is a constant problem with the MD80. We should have called ATC and requested relief from this restr.
