High-Temp Ammonia Heat Pump:Design & Lessons Learned

Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.

What Is a Boiler Feed Water Treatment System and How Does

Moreover, the water consumption is usually determined with the blow-down brine, depending on the recirculated steam and the make-up water concentration. B=S x (1 - r) x m / b - m. B = Blowdown. S = Steam rate. b = boiler water TDS concentration. m = make-up water TDS concentration. r = fractional condensate return

The excess being sufficient to give a small residual in the boiler water to produce sufficient ammonia, by decomposition of the hydrazine in the boiler, to raise the pH of the condensate to over 8.5. Continuous application by means of a suitable dosing unit, direct injected into …

Oxygen problems are especially severe where ammonia is present in significant quantities. In the presence of oxygen, ammonia is very corrosive to copper. The feed rate should be that shown in Table 3-5 plus 5 to 20 mg/L as sulfite Hydrazine decomposes in the boiler water at 400-600°F (250-1500 psia): 3N 2H 4 = 4NH 3 + N

– When the feed water pump comes on, the boiling point of water is reduced – Deareators use head pressure (1 psi for every 2.3 feet of height above the pump), where a feed water tank is barely 3 feet above the feed water pumps. – Watch the temperature closely to prevent pump loss due to cavitation.

It is estimated that problems due to boiler system corrosion cost industry billions of dollars per year. Many corrosion problems occur in the hottest areas of the boiler-the water wall, screen, and superheater tubes. Boilers that use undeaerated water during start-up and during their removal from service can be severely damaged
