Acoustic Cleaning Systems and the Alternatives. Steam Soot Blowers – the employment of these somewhat primitive and abrasive boiler tube cleaning systems is certainly in decline and have an ever increasing request to replace both the retractable lance and rotary type Soot Blower units with our Acoustic Cleaners and Sonic Soot Blowers.The reasons given by Power Generation plant engineers
Sootblowers clean boiler fireside deposits by extending a lance tube into the boiler and blowing high pressure steam directly onto the heat transfer surfaces of the boiler. The effectiveness of a
Steam Soot-blowers. Soot blowing is most commonly carried out using dry saturated or slightly superheated steam at boiler pressure. The use of dry saturated steam generally has a better impact effect in removing deposits than superheated steam, but precautions must be taken to preclude slugs of water from entering the boiler flueways.
Steam Soot Blowers . A common application at oil, coal, or multi-fuel source power plants is retractable or rotary steam soot blowers. Several steam soot blowers are usually found at each level of the boiler tower. A traveling lance with nozzle jets penetrates narrow openings in the boiler …
When the sootblower is retracted, 50% of the steam is used unnecessarily at the same time as the soft ash is sintered into concrete-like deposits. With HISS (High Impact Soot System), several sootblowers are operated in parallel with or without return steam, i.e. more sootblowing, less steam…
Steam soot blowers have specific advantage and disadvantages over other types. The advantages being mainly their low capital cost, operating cost and the effectiveness of cleaning in areas like furnace, superheaters and reheaters. There are many mechanisms that can cause erosion of boiler tubes at various heat transfer sections. Knowing the way these mechanisms contribute to erosion will help
A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency.. Types of soot blowers: Wall Blowers also known as IRs (Insertable Rotating) Long Retractable Soot Blower (LRSB) or IK (Insertable Kinetic) Air Heater Blower.
May 01, 2014· To facilitate this, soot blower, steam or air operated, are often fitted. They enable the tube surfaces to be cleaned of loose sooty deposits rapidly without shut down of the boiler. Figure below shows a typical soot blower arrangement fitted to a Scotch type boiler. Working
Below describes the measures necessary for implementation of High Impact Soot System (HISS), for optimization of steam soot blower and recovery boiler operation. Step 1 – Install pneumatic actuator on the steam soot blowers. The installation takes approximately 10 – 15 min per blower and can be performed during boiler operation.
Feb 05, 2018· Soot blowing is not cheap, so we do not want to spend more time and steam on soot blowing than necessary. Is there any way of soot blowing more, without spen
Summary: in this article, we give analysis to the design and model selection of acoustic cleaning system for the ESP (electrostatic precipitator) of 600MW boiler fire by lignite.We come up with the design & operation parameter for acoustic cleaning system. This article provides reference for successful application of sonic horn to remove soot deposit in ESP.
