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 ...

3 Pass Vacuum Hot Water Boiler--ZBG

Hot water in boiler chamber will flow three times in horizontal tubes which provides more opportunities for hot gasses to transfer heat to the water in a boiler. However boiler efficiency is highly affected by tube design and not simply the number of passes. 3-pass boiler with more heat transfer time to deliver the same or higher efficiency rating.
