摘要： 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.

摘要： A system for cleaning an interior of a boiler may include a lance tube operatively coupled to one or more positioning devices, and a cleaning tip coupled to one or more insertion devices. The lance tube may include a distal end from which pressurized water flows out of the lance tube into the interior of the boiler. The one or more positioning devices may be configured for moving the distal end of the lance tube in an X direction and/or a Y direction relative to a wall of the boiler to direct the flow of water from the distal end of the lance tube. The one or more insertion devices may be configured for moving the cleaning tip between a retracted position and an extended position.

摘要： A quench-cooling system has a primary quench cooler as a double-tube heat exchanger, a tube bundle heat exchanger as a secondary quench cooler. A tube bundle is enclosed by a casing, forming a casing room, which is formed between tube sheets arranged at spaced locations. Bundle tubes are held with the tube sheets. Parallel cooling channels, connected with one another, have a rectangular tunnel geometry formed (i) from the thin tube sheet, separating a gas side from a water/steam side and connected to a ring flange, which is connected to the casing of the enclosed tube bundle; (ii) from parallel webs, arranged on the tube sheet, separating individual water/steam flows from one another; and (iii) from a covering sheet, provided with openings for bundle tubes and defining the flow in the tunnel arrangement of the cooling channels.

摘要： A flexible high pressure fluid cleaning lance drive apparatus includes a guide rail having a longitudinal axis adapted to be positioned within a boiler water box and aligned in a fixed position with respect to a central axis of the water box. A tractor drive module is mounted on the guide rail, a helix clad high pressure fluid hose drive module is mounted on the guide rail operable to propel a flexible lance helix clad hose through the drive module along an axis parallel to the guide rail longitudinal axis, and a right angle guide rotator module is mounted on the guide rail and connected to the tractor module for positioning a rotatable high pressure nozzle carried by the helix clad hose within a guide tube attached to the rotator module.

摘要： A boiler ash remover based on a combined flow includes a frequency-adjustable acoustic flow generator, a fixing bracket, a compressed air source, a three-way air-source electric-control valve, an air jet generator, an acoustic-jet combined transmission tube, an acoustic jet intelligent control system, and a scale measurement and control sensor. The compressed air source is connected to an inlet end of the three-way air-source electric-control valve. An outlet end of the three-way air-source electric-control valve is connected to the frequency-adjustable acoustic flow generator and an air source inlet end of the air jet generator respectively. An acoustic flow outlet end of the frequency-adjustable acoustic flow generator is connected to an inlet end of the acoustic-jet combined transmission tube. An outlet end of the acoustic-jet combined transmission tube and a jet outlet end of the air jet generator are both disposed opposite to an external heat exchange component by means of the fixing bracket. The area of an acoustic flow transmission orifice at the outlet end of the acoustic-jet combined transmission tube covers that of a jet injection orifice at the jet outlet end of the air jet generator. The acoustic jet intelligent control system is connected to an electric control device of the three-way air-source electric-control valve and the scale measurement and control sensor respectively. The scale measurement and control sensor is disposed on the external heat exchange component. The boiler ash remover has the advantages of combining a frequency-adjustable acoustic flow with an air jet and implementing acoustic jet intelligent control, and has a desirable effect of removal of scales in a hearth or a flue gas heat exchanger.

摘要： A cleaning system and method for cleaning heat transfer surfaces in a boiler using a temperature measuring system for measuring and monitoring wall temperature of an annular wall of the tube of a lance of one or more sootblowers. Controlling a flow of steam or other fluid through the tube during the cooling portions of the strokes based on wall temperature measurements from the temperature measuring system. Infrared or thermocouple temperature measuring systems may be used. The steam or other fluid may be flowed at a default flowrate that may be substantially zero until the temperature measuring system indicates the wall temperature of the annular wall begins to exceed a predetermined temperature limit which may be the softening point of the annular wall. Then the steam or other fluid is flowed at a rate greater than the default flowrate.

摘要： A method of direct on-line measurement of thickness of fouling deposits created on the tube walls in a pulverized-coal firing furnace is described, as well as an apparatus suitable for implementation of the method. The method is based on imaging of a light spot, generated on the deposit surface by the apparatus. A position-sensitive image detector is used to track the spot as deposits accumulate, and the image signal is processed in real time, which allows for monitoring the creation of fouling deposits during operation of the furnace. The system simultaneously determines the reflectivity of the deposit surface. The apparatus can be used as part of an automatic soot blowing system.

摘要： A system and method to control of sootblowers in a fossil fueled power plant, in particular to plant applications systems using a graphical programming environment in combination with a set of rules to activate sootblowers. The system can be constrained by time limits and/or rule based time limits. Actual blower activation is typically based on the current status of key control variables in the process which alter the actual activation time within a constraints system. The system does not typically require knowledge or models of specific cleanliness relationships. The result is a system without sequences or queues that readily adapts to changing system conditions.
