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。<BR/> 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.
聲波吹灰器為什么能清灰的原因 在技術(shù)領(lǐng)域中,清灰技術(shù)最好的設(shè)備就是聲波吹灰器,而此設(shè)備為什么能清灰的原因,在日常的生活中很少有人能明白,那么我們今天就跟大家交流一下。<BR/> The reason why acoustic soot blowers can clean dust is the best equipment in the field of technology, and the reason why this equipment can clean dust is rarely understood in daily life.
鍋爐吹灰器清灰機(jī)理及實(shí)現(xiàn)的價(jià)值所在
在設(shè)備的運(yùn)行過(guò)程中,鍋爐吹灰器以高端的清灰機(jī)理以及自身?yè)碛械男阅苷紦?jù)市場(chǎng),由于灰粒子的表面的引力、粒子之間及粒子與爐內(nèi)管壁之間存在著一定粘結(jié)力、分子的附著力和靜電引力以及設(shè)備自然存在的化學(xué)親和力等多方面的性能作用,使設(shè)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(jié)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(shù)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.
