ABSTRACT:
A swing-arm sootblower for a rotary regenerative air preheater is mounted to sweep across the air preheater rotor at a constant speed or angular velocity. A constant speed motor is attached through a speed reducer to a drive sprocket. A chain drive turns driven sprocket which is connected to the rotatable mounting shaft for the sootblower lance or arm. Limit switches are tripped at the ends of the arc of travel of the lance by a trip arm mounted on the drive sprocket to turn the motor off and to close a valve for the sootblowing medium. The speed of the lance can be adjusted in general or at particular points in the art of travel.
