Zusammenfassung:	A steam generation system comprises: an oxygenated water treatment (OWT) sub-system (70) configured to generate water having oxidizing chemistry; a steam generation sub-system (8) configured to convert the water having oxidizing chemistry into steam having oxidizing chemistry; an attemperator (50) or other injection device or devices configured to add an oxygen scavenger to the steam having oxidizing chemistry to generate steam having less oxidizing or reducing chemistry; and a condenser (60) configured to condense the steam having less oxidizing or reducing chemistry into condensed water.
