General Electric Environmental Services, Inc. (GEESI) and APV Anhydro A/S (Anhydro) have chosen the direct drive approach for atomizers rated at 200 HP and above. This approach was selected to increase component life, improve reliability and reduce power transmission losses which are encountered in conventional gear-driven units. As an added benefit, the use of a variable frequency drive simplified atomizer speed changes, and provides lower inrush current than required with a conventional starter. This paper presents design and production considerations, laboratory tests results, and field experience with the GEESI variable speed, direct drive atomizer system. Data is presented on atomized droplet size characterization, power consumption, rotor vibration, bearing temperatures, and motor performance at various liquid flow rates and atomizer rotating speeds.
