3.6.1.Storage of Diesel Fuel
The most preferred method for providing a continuous fuel supply for the engine is fuel storage in tanks. The fuel
tanks can be installed under or above the ground.
There must be an air outlet point on the main fuel tank. The air pressure occurring while filling the tank and the
vacuum occurring during the fuel usage will be emptied by this air outlet point. Also a valve or a drainage point
must be used at a bottom point of the fuel tank, in order to be able to drain the water that may occur because of
condensation.
The fuel tank should be buried at a proper depth, so that the fuel should be protected against the frosty climate
conditions.
Another important point to be taken into account while using a main fuel tank is this; the difference of height
between the main and daily tanks. Noting that the standard electrical fuel lift pumps have a maximum pumping
capacity up to 5 meters, the difference of height between 2 tanks should not be exceeding this pumping height
capacity of the pump. Also note that too much use of horizontal pipes or elbow pipes will be decreasing the
fuel pressure on the suction line. For all these reasons; the locations of the fuel tanks and the piping to be done
between them, should be calculated and established well and carefully. The size of the fuel supply and return lines
should never be less than the sizes of the fuel connecting points on the engine and even they may need to be
increased to larger sizes in case for long-duration operations or in case of low ambient temperatures.
Fuel line pipes should be made from steel or a material suitable for petroleum. Do not use galvanized pipes. Tank
over flow pipe must be made from the same material and must be one size larger.
The fuel return lines should always enter the tank from a point above than the highest fuel level expected and there
should be no interruptions or valves on the fuel return line. In order to avoid any possible airlock problems, the fuel
return line should be designed and piped with minimum length and with minimum elbow/bending points. Also in
order to be sure that the fuel supplied for the engine is clean enough, the fuel to be supplied to engine should not
be taken from a height lower than 50 mm the base of the tank.
In order to avoid any possible risks to be caused by the vibrations on the generator set, the fuel lines should be
built with flexible pipes at the inlet points of the generator set.
