A cleaning system and method includes suspending and exploding, adjacent a bank of HRSG finned-tubing, a plurality of generally uniformly spaced detonation cords. Each detonation cord has an explosive grain loading of 18-50 grains per foot. A detonation delay assembly attached to each of the plurality of detonation cords creates a predetermined delay between each detonation cord explosion. After the detonation cords are exploded, a suspended elongated beam, having a transport assembly and a pressurized air blower assembly directs pressurized air towards an adjacent the bank of HRSG finned-tubing as the pressurized air blower assembly is moved along a portion of the beam. A suspension assembly moves the beam, the transport assembly, and the pressurized air blower assembly up or down so that a next portion of the bank of HRSG finned-tubing may be cleaned by the pressurized air.

The present invention provides an improved system and method for cleaning a plurality of semi-permeable heat exchange surfaces using an impulse wave which is transmitted by a distribution network and moved around the heat exchange surfaces by a navigational network.

The present invention is directed to an improved mobile combustion cleaning system for removing debris from a plurality of semi-permeable heat exchange surfaces with a moveable distribution network configured for receipt of a combustion mixture from a mobile cart according to a configurable controller the configurable controller generating the impulse wave from the combustion mixture and for moving the moveable distribution network along a plurality of axes in response to a change in pressure.

Optical fiber coating stripping through relayed thermal radiation is disclosed. A heat source is provided that is configured to emit thermal radiation when activated. A relay system is provided that is configured to receive the emitted thermal radiation from the heat source and relay the emitted thermal radiation to a heating region. For example, the relay system may be configured to relay (i.e., re-direct) the thermal radiation to a concentrated heating region. The heat source and relay system are configured such that thermal radiation relayed by the relay system causes the temperature in the heating region to reach or exceed a vaporization or thermal decomposition temperature of a coating(s) of an optical fiber to be stripped. When an optical fiber is disposed in the heating region, and the heat source is activated, a coating(s) of the optical fiber decomposes thus stripping the coating(s) from the optical fiber.

An appliance and a method for removing deposits from interiors of receptacles or facilities by way of explosion technology. The appliance includes a supply device for providing an explosive mixture or its starting components, as well as a transport conduit that is connected to the supply device and serves for transporting explosive mixture to a cleaning location. The transport conduit is designed at least in sections as a transport hose.

A process that uses a lodged projectile removal charge (LPRC) apparatus to remove a projectile jammed in a cannon's gun tube. The LPRC is positioned coaxially and offset from the projectile, and the gun tube is filled with water. The charge is detonated producing a shock wave that disintegrates the LPRC apparatus and pressurizes the water. The pressurized water produces a radial hydraulic force against an interior wall of the gun tube, an axial hydraulic force against the projectile pushing the projectile toward the chamber, and produces an opposing expansion of explosive gases that blasts out most of the water in the gun tube. The process is less likely to damage the gun tube. The LPRC may be made using a 3D printer.

The present invention provides a novel cleaning device capable of removing deposits on an exposed surface of a cleaning object in a short time. The cleaning device (1) of the present invention, for removing deposits on an exposed surface of a cleaning object (3) includes: a shock-wave generation section (2) that generates a shock wave; and a cleaning object storage section (4) that adjoins the shock-wave generation section (2) or stores the shock-wave generation section (2) therein and stores the cleaning object (3).

A method and cleaning device for removing deposits from interiors of receptacles and installations by way of explosion technology. The cleaning device includes a cleaning apparatus with a receiving space, and at least one pressure container that is connected via at least one metering fitting to the cleaning apparatus. The controlled introduction of the at least one gaseous component into the cleaning apparatus is effected according to the principle of the differential pressure between a maximal pressure at the beginning of the introduction and a nominal residual pressure after completion of the introduction. For this, based on a maximal pressure, the nominal residual pressure in the pressure container is ascertained on the basis of the quantity of gaseous component to be introduced, and the introduction of the at least one gaseous component is stopped on reaching the nominal residual pressure, which thereby lies in the overpressure range.
