來(lái)源：

在技術(shù)領(lǐng)域的支持下，總結(jié)出鍋爐吹灰器除灰內(nèi)燃的技術(shù)及原理，鍋爐的內(nèi)燃過(guò)程實(shí)際上是一種極其復(fù)雜的物理化學(xué)反應(yīng)過(guò)程，但是由于受燃煤的特性、受熱面上的結(jié)構(gòu)、爐內(nèi)的溫度場(chǎng)水平就越來(lái)越高及空氣動(dòng)力工況等物質(zhì)因素，造成整個(gè)受熱面積的灰與結(jié)渣，使鍋爐設(shè)備出力也不斷的下降。而國(guó)內(nèi)的動(dòng)力用煤多使用的是低品劣質(zhì)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(shì)，這就自然的加劇著受熱面的積灰結(jié)焦的過(guò)程形成。僅僅此設(shè)備就可通過(guò)鍋爐設(shè)計(jì)和運(yùn)行的調(diào)整，是不能夠快速的解決掉爐內(nèi)結(jié)灰結(jié)焦的問(wèn)題，所以使用鍋爐吹灰器是不可缺少的重要設(shè)備之一，使用到最合適的設(shè)備，直接會(huì)提高整個(gè)經(jīng)濟(jì)的效應(yīng)。目前國(guó)內(nèi)的鍋爐吹灰器與傳統(tǒng)的吹灰器普遍都存在著機(jī)械卡澀，熱態(tài)的進(jìn)退非常的困難，行程開(kāi)關(guān)造成失靈的現(xiàn)象，而鍋爐吹灰器作為最重要的新型吹灰設(shè)備，今年來(lái)已得到最廣泛的應(yīng)用，所以在吹灰機(jī)理上是通過(guò)聲波發(fā)生器，將一定的強(qiáng)度、頻率的聲波作用于鍋爐設(shè)備的本體內(nèi)各種可能積灰結(jié)焦的空間。而鍋爐設(shè)備處于高聲強(qiáng)高聲場(chǎng)范圍之內(nèi)的空氣分子及煙灰顆粒所產(chǎn)生的震蕩。所以設(shè)備在聲波震蕩的有力反復(fù)作用下，積灰就會(huì)不斷收到聲疲勞效力的循環(huán)作用，就會(huì)從而破壞整個(gè)煙灰顆粒與整個(gè)受熱面以及顆粒之間的巧妙結(jié)合，使之煙灰顆粒處于懸浮或流化狀態(tài)，在運(yùn)行的過(guò)程中煙氣流的作用下被帶走，達(dá)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.

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.
