The pH value of the water in the vaporization drum of the space furnace has recently been around 10. May I ask what the prices are at other manufacturers? What are the hazards of high pH? How to reduce it? What chemicals are usually added to the steam drum? How much more per hour? I hope everyone can explain in detail; thank you very much!
The pH of the feed water to the steam drum in a spacecraft furnace should be between 8.5 and 10.5; a value close to 10 should not pose any problems. Is it because the pH of the feed water is high? You can check the pH value of the drum feed water; if it is high, then reduce it. Also, the chemical added to the steam drum is usually phosphate, to prevent hard scaling in the steam drum system.
Don’t you have any standards for boiler water there? pH 9-10.5; total salt content less than 100 mg/L, SiO2 less than 2 mg/L, chloride ions less than 4 mg/L; phosphate level between 5-15 – add more if it’s too low, and discharge water if it’s too high. Regular discharge is required. These are the basic operating specifications for drum boilers; nothing special about them
Phosphate, hydrogen, sodium hydroxide – add whatever is necessary based on the analysis
