Black water in steam boiler - Boiler and Pressure

2004-1-19 · Black, magnetic debris in boiler feedwater loop (e.g. feedwater, boiler water, steam condensate) could be due to too much reducing agent (i.e.oxygen scavenger) as well as low pH. If oxygen is in excess I would expect to see some red-orange debris. Howver, oxygen can not be ruled out as a part of the cause of the black debris.
