ABSTRACT:
An apparatus for cleaning a gas tube includes an actuator and a plunger head attached to the actuator. The actuator is configured to reciprocate the plunger head along a longitudinal axis of the gas tube between a retracted position and an extended position and to rotate the plunger head from a first angular position to a second angular position. A method of cleaning a gas tube includes positioning a plunger head including a plurality of longitudinally extending tines in the gas tube, rotating the plunger head relative to a longitudinal axis of the gas tube, and scraping deposits from an interior surface of the gas tube using longitudinally extending edges of the tines.
