摘要： An apparatus is provided for cleaning a surface within a vessel. A vessel wall separates a vessel exterior from a vessel interior and has a wall aperture. The apparatus comprises an elongate conduit having an upstream first end and a downstream second end. The conduit is positioned to direct a shock wave from the second end into the vessel interior. A source of fuel and oxidizer is coupled to the conduit to deliver the fuel and oxidizer to the conduit. An initiator is positioned to initiate a combustion of the fuel and oxidizer. The conduit comprises a first portion and a second portion downstream of the first portion. The second portion is extensible and contractible relative to the first portion to selectively position the second end at a desired location within the vessel. The conduit downstream end comprises a centerbody positioned to direct the shock wave essentially axisymmetrically.

摘要： The burning of fuel (e.g., coal) in industrial equipment generates an exhaust flow containing airborne particulate. The flow is passed through a rotary heat exchanger to preheat inlet air. The heat exchanger element is subject to fouling and is cleaned by a pulsed combustion device. The device is operated by introducing a fuel and oxidizer charge to at least one conduit and initiating combustion of the charge. The combustion generates a shock wave to which the element is exposed, dislodging and/or otherwise removing the deposits.
