1. A sootblower for cleaning a plurality of surfaces within an interior volume of a combustion device, the sootblower comprising:
- a combustion assembly configured to generate a pressure wave;
a delivery assembly defining a pressure wave path extending in a substantially linear direction between the combustion assembly and an outlet portion of the delivery assembly; and
a translating assembly configured to translate the delivery assembly in a forward direction, from a resting position to an operational position, along a translation path generally parallel to the pressure wave path to selectively position the outlet portion of the delivery assembly within the interior volume of the combustion device and deliver the pressure wave along the pressure wave path, in the forward direction, into the volume of the combustion device and remove deposits from the surfaces of the combustion device.
