Where should the recirculation outlet of the boiler feedwater pump be connected?

Thread Content

A few days ago, I saw that at one facility, the recirculation outlet of the boiler feed pump led directly into the inlet pipe of the pump. What are the advantages and disadvantages of doing this? :)

The technically appropriate location for the feed pump recirculation outlet is the deaerator feed water tank; connecting it to the feed pump inlet is incorrect

It should work no matter where it is connected; the piping design of the circuit must conform to the output characteristics of the pump
