For catastrophic failure and loss of life to be avoided, a steam boiler must have the correct amount of water. The feedwater pump has to be sized for flow that is a certain percentage higher than what the boiler requires for normal operation.
It also is important to be cognizant of the vented-receiver or deaerator water temperature and the presence of treatment chemicals, both of which can have an impact on materials of the pump and mechanical seal.
Steam-boiler systems are available in a broad range of sizes. The following steps apply to pump selection for an industrial steam boiler with a horsepower range of 100 to 1,200 and a design pressure of 150 to 500 psig. Read more.
