  • Boiler Feedwater Treatment (Part II): Water Treatment

    Ammonium hydroxide (NH4OH) is a solution of ammonia in water. Commonly called ammonia or ammonia water, the chemical is used as a cleanser and in manufacturing plastics, rubber, fertilizer and textiles. It's a colorless, clear liquid with a pungent-to-faint ammonia odor. Stable under normal temperatures and pressures, heating it produces ammonia gas.Learn More

  • Feed Water Treatment to Avoid Corrosion - Engineering ToolBox

    Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Corrosion is a major problem in steam systems with high consumption of make-up water. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems.Learn More

    – 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.Learn More

  • Using Water Heaters for Radiant Heat

    the heater is on standby. Averaged in, this lowers the unit's efficiency rating. Adding a heating load, however, increases average efficiency because the tank operates more frequently at its higher steady-state combustion efficiency of 76% to 80%. The efficiency you get from a boiler or a water heater relates more to how you use it than what'sLearn More

  • How to Balance NH3 + H2O = NH4OH (ammonia and water) - …

    To bind carbon dioxide in the condensate and prevent carbon dioxide corrosion, ammonia water is dosed into the feed water. Ammonia reacts with water to form ammonium hydrate (NH 4 OH). This increases the pH and electrical conductivity of the feed water. In the boiler, the ammonia evaporates with steam.Learn More

  • Boiler feed water - Lenntech

    The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).The make-up water is usually natural water either in its raw state, or treated by some process before use.Learn More


    2. Internal treatment: Treatment of the boiler feed water, boiler water, steam, or condensate with corrective chemicals. 3.

  • Acid Cleaning Operation for Scale Attacked Water Wall

    The cleaning mechanism and the passivation on cleaned surface of boiler WWTs by 2.0% NaNO3 in presence of 0.5 % NH4OH (pH 10.5) at 55OC were found to be satisfactory. Close macro-structural examinations (by SEM) of the tube materials after the TSAE operations reveled there is no remarkable corrosion or micro creaks on boiler WWTs materials.Learn More
