Hardness ions (calcium, magnesium) in the boiler feed water enter into a chemical reaction at high temperatures or crystallize when the saturation concentration is reached, forming an insoluble scale that adheres tightly to the heated surfaces of the boiler.
Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of hydrazine solution to the boiler feedwater reacts chemically with the dissolved oxygen (O₂) in the feedwater to form nitrogen and water.
Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of ammonia water (NH₂OH) or liquid ammonia (NH₃) to the boiler feed water to increase the pH of the feed water (usually maintained in the range of 8.8–9.3 or depending on specific conditions) allows the formation of a stable protective film of magnetite (Fe₃O₄) on the surface of the metal (for example, carbon steel).
