WARNING: make sure that the feeding line is properly dimensioned and is in compliance the local safety rules and code of practise in the
country of installation.
INSTALLATION
Heavy oil preparation ring
All installations using heavy oil burners have
to be completed with a forced oil preparation
ring in order to guarantee oil supply to the
burner at suitable temperature and pressure
(tempe/- 50° C, pressure 3 bar).
For heavy oil with more than 50°E at 50°C
Ecoflam recommends to lower the maximum
output of 10-20% and work in excess of air in
order to grant better operation and reduce
maintenance.
Installation with heavy oil must provide to
the burners:
- CONSTANT PRESSURE
- CONSTANT TEMPERATURE
To size correctly the ring for the heavy oil supply
consider the diagram of the pre-heating
temperature of the heavy oil according to
viscosity and the pump pressure according to
temperature.
Ecoflam heavy oil and dual fuel heavy oil
burners do have in the electrical panel the fuel
temperature device GEFRAN that adjusts the
temperature of the heavy oil and grants
temperature stability.
