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.

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.
