PRESSURE DROP DIAGRAM
The diagrams indicate the minimum pressure drop of the burners with the various gas trains that
can be combined with them; the value thus calculated represents the minimum required input
pressure to the gas train.

For pressure levels different from those indicated above, please
contact Riello Burners Technical Office.
In LPG plants, Multibloc gas trains do not operate below 0

C.
They are only suitable for gaseous LPG (liquid hydrocarbons destroy
the seal materials).
