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

/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.
