摘要

Boiler feedwater (BFW) pumps are an important part of many different industrial plants and facilities. These pumps are a special class of high-pressure centrifugal pumps used in many different models and sizes in many different plants, units, and production facilities. However, BFW pumps are not well-known by many engineers and operators. Too often, improper operation or mistakes in maintenance and repair due to lack of knowledge or experience have resulted in damages and serious problems. High-purity BFW is required to ensure proper operation of any boiler or steam generation system. High-purity feedwater reduces the use of boiler chemicals due to less frequent blowdown requirements, reducing blowdown frequency by as much as a factor of 10 or 15. This results in lower fuel costs and better overall operation of boiler or steam generation systems. Scale build-up is reduced due to a smaller concentration of impurities in BFW to foul heat transfer surfaces. Fewer impurities also means reduced corrosion rates in all associated parts and components
