在技術領域的支持下，總結出鍋爐吹灰器除灰內燃的技術及原理，鍋爐的內燃過程實際上是一種極其復雜的物理化學反應過程，但是由于受燃煤的特性、受熱面上的結構、爐內的溫度場水平就越來越高及空氣動力工況等物質因素，造成整個受熱面積的灰與結渣，使鍋爐設備出力也不斷的下降。而國內的動力用煤多使用的是低品劣質煤，鍋爐的燃煤多存在變且灰份也非常的大、熱值也在不斷的降低的趨勢，這就自然的加劇著受熱面的積灰結焦的過程形成。僅僅此設備就可通過鍋爐設計和運行的調整，是不能夠快速的解決掉爐內結灰結焦的問題，所以使用鍋爐吹灰器是不可缺少的重要設備之一，使用到最合適的設備，直接會提高整個經濟的效應。目前國內的鍋爐吹灰器與傳統(tǒng)的吹灰器普遍都存在著機械卡澀，熱態(tài)的進退非常的困難，行程開關造成失靈的現象，而鍋爐吹灰器作為最重要的新型吹灰設備，今年來已得到最廣泛的應用，所以在吹灰機理上是通過聲波發(fā)生器，將一定的強度、頻率的聲波作用于鍋爐設備的本體內各種可能積灰結焦的空間。而鍋爐設備處于高聲強高聲場范圍之內的空氣分子及煙灰顆粒所產生的震蕩。所以設備在聲波震蕩的有力反復作用下，積灰就會不斷收到聲疲勞效力的循環(huán)作用，就會從而破壞整個煙灰顆粒與整個受熱面以及顆粒之間的巧妙結合，使之煙灰顆粒處于懸浮或流化狀態(tài)，在運行的過程中煙氣流的作用下被帶走，達到最佳的除灰目的。


　　With the support of the technical field, the technology and principle of internal combustion in boiler soot blower have been summarized. The internal combustion process of the boiler is actually an extremely complex physical and chemical reaction process. However, due to the characteristics of coal, the structure of the heating surface, the temperature field level inside the furnace becoming higher and higher, and aerodynamic conditions and other material factors, the ash and slag deposition in the entire heating area are caused, resulting in a continuous decrease in the output of the boiler equipment. However, domestic power coal mostly uses low-grade and low-quality coal, and the coal used in boilers tends to change, with a high ash content and a continuous decrease in calorific value. This naturally exacerbates the process of ash accumulation and coking on the heating surface. Only this equipment can be adjusted through boiler design and operation, which cannot quickly solve the problem of ash and coking in the furnace. Therefore, using a boiler soot blower is one of the indispensable and important equipment. Using the most suitable equipment will directly improve the overall economic effect. At present, both domestic boiler soot blowers and traditional soot blowers generally have mechanical jamming, making it very difficult to move in and out of the hot state, and the phenomenon of stroke switch failure. As the most important new type of soot blowing equipment, boiler soot blowers have been widely used this year. Therefore, in terms of soot blowing mechanism, a sound wave generator is used to increase the strength The sound waves of frequency act on various spaces within the boiler equipment that may accumulate ash and coke. The vibration generated by air molecules and soot particles in the range of high sound intensity and high sound field of boiler equipment. So under the strong and repeated action of sound waves, the accumulated ash of the equipment will continuously receive the cyclic effect of sound fatigue, which will destroy the clever combination between the entire ash particles and the entire heating surface as well as between the particles, making the ash particles in a suspended or fluidized state, and being carried away by the smoke airflow during operation, achieving the best ash removal purpose.

鍋爐吹灰器清灰機理及實現的價值所在

在設備的運行過程中，鍋爐吹灰器以高端的清灰機理以及自身擁有的性能占據市場，由于灰粒子的表面的引力、粒子之間及粒子與爐內管壁之間存在著一定粘結力、分子的附著力和靜電引力以及設備自然存在的化學親和力等多方面的性能作用，使設備在爐膛及煙道各部位的換熱面上不斷的逐步形成積灰結焦。而鍋爐吹灰器中的煙氣灰粒是一種寬篩分組成，所以大部分都是小于220um，其中多數為10~30um的微小粒。<BR/> During the operation of the equipment, the boiler soot blower occupies the market with its high-end cleaning mechanism and its own performance. Due to the surface attraction of ash particles, the presence of certain bonding forces between particles and the furnace wall, molecular adhesion and electrostatic attraction, as well as the natural chemical affinity of the equipment, and other performance effects, Gradually form ash and coking on the heat exchange surfaces of the furnace and flue of the equipment. The flue gas ash particles in the boiler soot blower are composed of a wide sieve, so most of them are smaller than 220um, with most of them being small particles of 10-30um.
