What type of make-up water pump is commonly used in power plant boilers?
Same question: should a centrifugal pump or a positive displacement pump be used?
A multi-stage pump is used to supply water to the boiler
The boiler feed water pump is a multi-stage centrifugal pump
Centrifugal feed water pumps are generally used, and it also depends on the size of your boiler! For example, for a capacity of 130 t/h and a head of 9.81 m, a centrifugal pump of grade 12 with a head of 1500 m is generally used
Boiler make-up water and boiler feed water are not the same thing; it’s not appropriate for Mr. Xiaocao to use a 12-stage centrifugal pump with a head of 1500 mm for making up water in a 130t/h boiler. Boiler make-up water refers to the water added to the boiler water; high-pressure pumps aren’t needed for that purpose!
For multi-stage centrifugal pumps, it depends on the pressure required
