FEEDWATER WATER AND SOLIDS SATURATED STEAM EVAPORATED WATER Continuous blowdown to remove dissolved solids in boiler water Intermittent blowdown to remove suspended solids in boiler water Blowdown - Removes boiler water with a high concentration of solids which is replaced by feedwater containing a low concentration of solids WATER AND SOLIDS Boiler feed pump KSBBoiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed pumps regarding

Jan 23, 2020 · The most familiar form of oxygen attack in boilers and condensate systems is oxygen pitting. Oxygen pitting is a problem for both ideal as well as boiler which is in operating conditions. Super heater & reheater tubes for ideal boiler and economiser & feedwater heaters for operating boiler are the favorable attack places.Characteristics of boiler feedwater? - Answers
- Characteristics of boiler feedwater?
- BOILER FEEDWATER Feed water have a low mineral content, a low chloride content, a low dissolved oxygen content and a pH of above 7-8. As the purpose of the boiler is to evaporate water, the low mi
