Fuel heater control example
Most marine and land-based engine/burner applications use a fuel booster module to precondition the
heavy fuel oil (HFO) prior to injection. These modules usually consist of a number of supply pumps fed by
either HFO or MDO, a flow meter, in-line filters to remove the impurities, and a holding/mixing tank.
Following the supply section, the fuel is usually sent to booster pumps that increase the flow rate up to a
maximum of 20 m
3
/hr and then through a series of heat exchangers (liquid or electric) to change the product
viscosity for efficient combustion.
Following is a graphic that shows the different installation options for the 7829 Viscomaster Dynamic in a fuel
booster module.
