FUEL FEED UNIT
The burner pump must receive the fuel from a suitable feed circuit with an auxiliary pump having a pressure that is
adjustable between 0.5 and 2 bar; if fuel of a rated viscosity greater than 5 °E at 50 °C is to be used, it must be
preheated to 50 - 60 °C.
Fuel feed pressure at the burner pump (0.5 - 2 bar) must be practically constant both with the burner at standstill
and with the burner working at the maximum fuel feed rate requested by the boiler.
The feed circuit must be as illustrated in our drawings (shown below) even where low viscosity fuels are used.
Piping must be sized as a function of both its length and the flow-rate of the employed pump.
Our instructions regard only that which is necessary for proper operation.
