Power plants: Fuel oil filtration in booster system

Power plants fuel feed system

This feed system (hot circuit) transports the fuel from the mixing tank to the engine. The system consists primarily of the supply pumps (redundant), pump protection filters, an automatic filter with a defined filtration rate, a preheating system, a viscosity control unit, and an engine protection filter.

The fuel is transported via the supply pumps, screened by the pump protection filters, through the automatic filter (fine filtration). The preheating system and viscosity control unit ensure that the temperature and viscosity are correct throughout the entire circulation system. The duplex filter mounted directly in front of the engine serves as a final and decisive safeguard.

The mixing tank is also holding the excess fuel from the engine.


BOLLFILTER as pump protection

The pump protection filters, which are equipped with a coarse filter element, are located on the suction side of the supply pumps and protect the redundant pumps in order to guarantee a secure fuel supply.


BOLLFILTER as protection for the engine

The automatic backflushing filter type 6.72.1 cleans itself based on an adjustable period of time or by reaching a differential pressure due to the collection of contamination. In addition, this type of filter can be outfitted with a change over valve and attached by-pass filter (optional), which also ensures the supply of filtered fuel while performing maintenance.
