LOADING AND SUPPLY OF THE GENERATOR/SYSTEM

The steam generator is fed with a multistage centrifugal pump. The water must reach the pump intake with a certain head in order 
to avoid cavitation.
The minimum temperature of the sucked water must be greater than 60°C; this favours the elimination of oxygen which, in any 
case, must be completely eliminated with suitable chemicals. Also, a water temperature > 60°C reduces the risk of thermal shock 
in the boiler.
The feed tank must be positioned at a height that depends on the temperature of the water in the degasser/feed tank, on the con-
formation of the degasser/pump-feed tank connection pipe and on the features of the pump itself (refer to the pump manual).

ATTENTION

 

The oxygen dissolved in the water corrodes the boiler. Refer to the maximum allowed values indicated in the relevant 
section of the technical manual.

 

Follow the table below to avoid pump cavitation problems.

  Maximum pump suction temperature is 120°C.

IMPORTANT

 

Avoid using feed water at a temperature below 60°C because rich of dissolved oxygen, thus such to cause corrosion.
