During the normal operation of the fuel oil centrifuge shown in the illustration, the flow from the port labeled "B" should be __________. See illustration MO-0012.
• Flow paths in a fuel oil purifier/clarifier centrifuge (oil outlet, water outlet, sludge discharge) • Relative densities of fuel oil, water, and sludge and where each layer forms in the bowl • Normal operation vs sludge ejection cycle in a self‑cleaning centrifuge
• In the illustration, which outlet (A, B, or C) is connected to the inner, lighter layer and which to the outer, heavier layer in the bowl? • During normal running (not a sludge discharge), which products are removed continuously, and which are removed only intermittently? • Would thick sludge reasonably flow through a small, upper side outlet, or is it more likely expelled from the bowl rim/ports at the periphery?
• Trace the color shading in the drawing from the separated oil layer and water layer up to outlets A, B, and C. • Decide which discharge (oil, water, or sludge) should be continuous during normal purification of fuel oil. • Confirm that sludge in these machines is normally discharged from ports in the bowl periphery, not through the small top outlets.
