| 20080250598 | SOOTBLOWER HAVING A ROTATIONAL DELAY MECHANISM - A sootblower to project a blowing medium into a boiler is disclosed herein. The sootblower includes a hub, in which a first end of the hub is configured to receive a lance and a second end of the hub is configured to receive the blowing medium. The sootblower further includes a drive assembly configured to convert bidirectional rotation from a drive shaft to bidirectional rotation for the hub. The drive assembly then includes a rotation delay mechanism configured to delay a transition between a first directional rotation and a second directional rotation of the bidirectional rotation for the hub with respect to the drive shaft when the drive shaft is transitioning from a first directional rotation to a second directional rotation of the bidirectional rotation for the hub. | 10-16-2008 |
| 20080250597 | DUAL-MOTOR SOOTBLOWER - A sootblower to project a blowing medium into a boiler is disclosed herein. The sootblower includes a hub, a first motor, a second motor, a gear train, and a drive shaft. The hub comprises a first end to receive a lance and a second end to receive the blowing medium. Further, the gear train is configured to convert rotation of the first motor into rotation of the lance, and the drive shaft is configured to convert bidirectional rotation of the second motor into translational motion of the lance. | 10-16-2008 |
| 20080216277 | VARYING HELICAL SOOTBLOWER - A sootblower to project a blowing medium into a boiler and a method of cleaning a boiler using a sootblower are disclosed. The sootblower includes a hub disposed within a housing, in which ends of the hub are configured to receive a lance and the blowing medium. A drive shaft of the sootblower is then configured to rotate the lance with respect to the boiler in a rotational direction at a first ratio relative to the drive shaft when the drive shaft is rotated in a first direction, and is configured to rotate the lance with respect to the boiler in the rotational direction at a second ratio relative to the drive shaft when the drive shaft is rotated in a second direction. | 09-11-2008 |
