Water Handbook - Preboiler & Industrial Boiler Corrosion

Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low. High-temperature hot water boilers operate at pressures of up to 500
