Title: Sound waves in the power plant ash technology application
ABSTRACT
In all kinds of boiler equipment (including boiler and industrial boiler, coal-fired boilers and oil burning boiler flue chamber and the various surface of heat exchanger, almost without exception, appear with ash slagging, ash and slag phenomenon of "reduces the boiler efficiency, serious when still can affect the safe operation of the boiler equipment, was forced to stop furnace slag removal of artificial qing coke, thereby reducing the boiler efficiency and service life, enhance the worker's Labour intensity even casualty accident happen. Facing this long exists some problems of the boiler, and successively developed long telescopic high-pressure steam sootblowers, rotary steam sootblowers, high-pressure hydraulic ash, steel (vibration) ash, etc all kinds of dust removal equipment, but there are still some of these devices on the function of the restrictions and defects, actually use efficiency is low, the most leave unused. A few even, also can use for local surface of heat exchanger, overall benefit to reflect.
China began to research the acoustic blowing in the 1980s, enter the 10, acoustic blowing technology research is very active, during which has many research institutes have introduced various acoustic sootblowers. Application in power plant, in different extent achieved certain benefits.
Acoustic blowing, as a new technology, blowing vigorously developed. But because of this technology is also being studied, acoustic blowing technology application with great blindness. Acoustic blowing from the mechanism, this paper discusses the advantages and disadvantages of the blowing sound waves, analyzes the technology and application situation, and points out its development trend.
