Abstract:
1. An apparatus for removing hot gas deposits from a system via pressure pulses, comprising: an expansion chamber configured to receive a mixture of detonation fluid and oxidizer; an initiator; a first control device configured to regulate flow of detonation fluid; and a second control device configured to regulate flow of oxidizer, the first control device and the second control device selectively operable in a first mode of operation and a second mode of operation; and a controller in communication with the initiator, the first control device, and the second control device, the controller configured to: selectively control operation of the first control device and the second control device in the first mode of operation to regulate flow of detonation fluid and oxidizer periodically into the expansion chamber, or the second mode of operation to provide a continuous flow of detonation fluid, and one of a continuous supply and selective prevention of oxidizer to the expansion chamber, and control operation of the initiator to ignite the mixture of detonation fluid and oxidizer during the first mode of operation to create a detonation, the detonation configured to create a high pressure wave that substantially removes hot gas deposits while the system is in fired operation, and initially ignites the mixture of detonation fluid and oxidizer in the second mode of operation.
