BOILER CONNECTION
WATER CONNECTION
The hard water reaches the conditioning plant. This must be surrounded by
dividing wall; the floor should possibly be made in “gres”; independent drain
for backwashing the conditioner. When the softened water leaves the
conditioner it must then be forwarded to the purified water and condensate
collecting tank.
The condensate tank, especially if the water is at high temperature, must have
a minimum head of about 1.50 meters over the generator pump level.
RELATION BETWEEN THE WATER TEMPERATURE AT THE PUMP
AND HEAD, NECESSARY TO AVOID THE CAVITATION.
The connection piping between the tank and boiler must have an adequate
diameter.
Never make a rigid fitting between the boiler piping and pump - Interpose m.
0.30 of high temperature resisting flexible rubber hose.
Do not use elbows but bend pipes to avoid head loss.
A breather pipe should be applied to the condensate collecting tank and let
through to the outside of the room to discharge the fumes.
It is recommendable for the water pipings and tank to be galvanised.
