解決積灰結(jié)渣的好幫手—鍋爐吹灰器

來(lái)源：

　　我們都知道鍋爐積灰結(jié)渣是件非常令人頭疼的事，不但會(huì)降低鍋爐的熱效率，還會(huì)大大縮短鍋爐的使用壽命，結(jié)果就是給鍋爐使用單位造成巨大損失。那么如何解決這個(gè)問(wèn)題呢？就要用到我們今天介紹的主角—鍋爐吹灰器。
　　We all know that the accumulation of ash and slag in boilers is a very headache. It not only reduces the thermal efficiency of the boiler, but also greatly shortens the service life of the boiler, resulting in huge losses to the boiler users. So how to solve this problem? We will use the protagonist we introduced today - the boiler soot blower.
解決積灰結(jié)渣的好幫手—鍋爐吹灰器
　　首先我們來(lái)了解一下什么是鍋爐積灰結(jié)渣。鍋爐積灰結(jié)渣是指燃料燃燒時(shí)所產(chǎn)生的大量微小灰粒在隨煙氣流向出口的過(guò)程中，由于灰粒子的表面張力、粒子之間及其爐內(nèi)管壁之間的黏滯力、分子附著力、靜電吸引力以及化學(xué)親和力等多方面的作用，在鍋爐的爐壁及煙道各部分的換熱面上的積聚。燃料的成分、鍋爐負(fù)荷及燃燒工況、鍋爐噴燃裝置都會(huì)對(duì)鍋爐的積灰情況產(chǎn)生影響。
　　First of all, let's understand what boiler ash accumulation and slagging are. Boiler ash accumulation and slagging refer to the accumulation of a large number of small ash particles generated during fuel combustion, as they flow towards the outlet with the flue gas. Due to the surface tension of the ash particles, the viscous force between particles and their inner tube walls, molecular adhesion, electrostatic attraction, and chemical affinity, they accumulate on the heat exchange surfaces of the boiler wall and flue sections. The composition of fuel, boiler load and combustion conditions, as well as the boiler spray combustion device, all have an impact on the ash accumulation in the boiler.
　　鍋爐積灰結(jié)渣是個(gè)普遍存在的問(wèn)題，對(duì)于鍋爐運(yùn)行的經(jīng)濟(jì)性影響很大。加熱爐受熱面的積灰不僅影響受熱面的傳熱效率，導(dǎo)致?tīng)t子效率下降，而且由于除灰措施不當(dāng)或除灰技術(shù)自身的局限性，導(dǎo)致加熱爐受熱面的積灰日趨加劇，影響加熱爐后期的穩(wěn)定運(yùn)行。當(dāng)受熱面積灰和結(jié)渣嚴(yán)重時(shí)，還可能導(dǎo)致意外停爐，造成重大經(jīng)濟(jì)損失。因此鍋爐受熱面一定要定時(shí)淸掃、吹灰，采用鍋爐吹灰器是消除積灰、堵灰的有效方法。
　　Ash accumulation and slagging in boilers are a common problem that has a significant impact on the economy of boiler operation. The accumulation of ash on the heating surface of the heating furnace not only affects the heat transfer efficiency of the heating surface, leading to a decrease in furnace efficiency, but also intensifies due to improper ash removal measures or the limitations of ash removal technology, which affects the stable operation of the heating furnace in the later stage. When the heating area is severely dusty and slagging, it may also lead to accidental shutdown, causing significant economic losses. Therefore, the heating surface of the boiler must be regularly cleaned and blown, and using a boiler soot blower is an effective method to eliminate dust accumulation and blockage.
