What are the boiler water control parameters for the catalytic external heat exchanger drum? What are the ranges? (This steam drum is designed for a pressure of 4.0 MPa.) So, what are the specifications set by your factory?

It’s in the design documents; it’s best to check your original design documents yourself

Water quality parameters for drum boilers: Silica: ≤2.00 mg/L; Chloride ions: no specified limit; Conductivity (at 25°C): <60 us/cm; Phosphates: 2–6 mg/L; pH (at 25°C): 9.0–10.0; Alkalinity (expressed as CaCO3): 0 (maximum 2 ppm) per DPT standards; Total solids: <50 ppm per DPT standards
