Abstract: Aiming the problems existing in all volatilization treatment process in which ammonia and hydrazine are adding to the feedwater of supercritical unit, an advanced combined feedwater treatment process was put forward in which the oxygen and hydrazine are adding to the feedwater. The comparison of the two process was given, and control indications of the water quality in the second process were put forward.

Key words: supercritical unit, quality of steam and water, control
