Rotary Cup Atomizers

 

 

Rotary-cup atomizers are driven at high speeds (about 500 rpm) by an electric motor and heavy-duty belt drive. Fuel oil flows at low pressure into a conical spinning cup, where the fuel is distributed uniformly on the inner surface and thrown off the cup rim as a very fine oil-film. A fan discharges the primary air concentrically around the cup, strikes the oil film at high velocity, and atomizes it into tiny droplets. Rotary-cup atomizers are often used with packaged shell-type burners. These burners have good turndown ratio and are relatively insensitive to pollutants in the fuel oil.
