Water quality parameters for heavy oil catalytic external heat extraction boiler
Thread Content
Which sea friend can send them? Urgently need the control parameters for the drum boiler water! Thanks first!
Reply to 1# liurf1975: Furnace water pH value: 9~11; Phosphate ion concentration: 5~15mg/L; Chloride ion concentration:
Boiler water pH: 10–12 Phosphate ion concentration: 10–30 mg/L Chloride ion concentration:
