解決6噸熱水鍋爐尾部受熱面磨損問題

處理6噸熱水器煤氣鍋爐尾端熱膨脹面磨花故障

Solve the problem of heating surface of 6 tons of hot water boiler

6噸溫熱水水器流入頂部廚房煙道的飛灰致使溫度表較低，具必要的對抗強度，之所以隨工業廢氣基礎加熱面管溝時，會對管內發生破損的功效。特別的是省煤器，入口煙溫已減少為450°C時間，灰粒較硬，且適用小的直徑薄壁管高碳鋼管，更易得到破損破損。另外破損也正省煤器爆管在燃氣鍋爐四管鉆爆特大事故中占的比率較高的緣故之三。

The fly ash that enters the tail flue is because of the low temperature, it has certain hardness, so as the exhaust gas primary heating plane pipe, it will wear effect to the wall of the pipe. Especially the economizer, import the smoke temperature has fallen to about 450 ° C, ashes is hard, and using small diameter thin-walled carbon steel tube, are more susceptible to damage of wear and tear. And wear is one of the reasons that the coal burner has a higher proportion of the boiler's four pipe blasting accidents.

包含硬粒飛灰的氮氧化物相對于于管厚外溢，對管厚導致輪胎剎車盤磨壞可稱蠕變輪胎剎車盤磨壞，也稱沖蝕。沖蝕有腐蝕輪胎剎車盤磨壞和擊中輪胎剎車盤磨壞二者基礎業務類型。二者輪胎剎車盤磨壞的金屬材質掉失流程的外部經濟型態不會是完全重復的。

The flue gas that contains the hard particle fly ash is relative to the flow of the wall of the pipe, and the damage to the wall of the tube is called the impact wear, also called erosion. erosion

There are two basic types of erosion wear and impact wear. The microscopic appearance of two worn metal loss processes is not exactly the same.

沖洗受損是灰粒比較管內外從界面的沖撞角較小，因此將近拋物線。灰粒垂直面于管內外從界面的分立使它楔入被沖撞的管內，而灰粒與管內外從界面相切的分力使灰粒沿管內外從界面滾輪，幾個分立分解成的結果顯示起另一種對管內外從界面磨削的的功效。

The erosion of the ash is smaller and even close to parallel than the surface of the surface of the ash. Soot particle separation to make it on the surface of the perpendicular to the pipe wall wedging the shock tube wall, and ashes and wall surface tangent component makes ashes sliding along the wall surface, synthetic results of two separate ACTS as a cutting on the surface of a wall.

假如管外經得住不了協力的切屑使用，就出現黑色金屬粒狀剝落孕媽而離職。在非常多的飛灰長時間經常切屑使用下，管外外層將形成有損壞。
