The speed of the steam boiler heating surface is related to the velocity of the smoke, the concentration and hardness of the ash particles in the flue gas, the arrangement of the tube bundle, etc. the velocity of the flue gas has the greatest influence on the wearing of the heating surface. The test results show that the wear rate of the heating surface pipe is proportional to the three times of the flue gas velocity, so it is necessary to control the flow velocity of the flue gas effectively.
2噸飽和蒸汽加熱爐熱傳遞面的損壞轉速與尾氣的流動車速、尾氣中灰粒的滲透壓及洛氏硬度、列管的安裝原則等情況有關，至少尾氣的流動車速對熱傳遞面的損壞會影響極限。檢測精確測量，熱傳遞面散裝洗潔精泵的損壞轉速與尾氣流動車速的倆次方不成比例，因需求很好地對尾氣流動車速做好把握。
The furnace wall leakage, local wall flue ash, flue gas flow rate of local convection heating surface will cause severe local slagging in the flue is too large, so that the heating surface tube local wear intensifies, in addition, when the blower working poor, high-pressure steam will blow the heating surface of the pipe corrosion, the pipe wall thinning.
爐墻的風噪大，廚房煙管的部位墻灰，過流吸熱面部位頻發結渣都要 使廚房煙管的部位尾氣流動速度過大，使吸熱面排水管部位受損誘發，其他，當吹灰器操作惡意時，超高壓飽和蒸汽式飽和蒸汽式會將吸熱面的排水管吹蝕，使管內減薄。
Wear often occurs in region heating surface pipe is: cold ash hopper, burner, water wall tube flame fold corner, manhole and blowing hole near the steering room before the vertical flue gas; the heating surface of the lower tube; horizontal tail vertical flue heating surface tube upper part two or three pipe and the lower pipe, pipe section two or three support clip edge, near the furnace wall side row pipe and pipe pipe and other prominent individual.
吸熱面水管接頭變形一直發現的范圍是：冷灰斗、引燃器、折焰角、人孔門并且吹灰孔隨近的水冷散熱壁水管接頭;煙塵轉移到室前立柱式吸熱面的上面水管接頭;尾端豎向排煙道的立式吸熱面管排上面二、3根水管接頭、上面二、3根水管接頭、水管接頭支承卡子邊界臟器、鄰近爐墻的邊排水管接頭及某一出色管排的水管接頭等。
Method of reducing heating surface abrasion are: reduce boiler load, reduce the velocity of flue gas; burning coal in high quality, reduce the content of fly ash in flue gas steam boiler; change the tube arrangement, the staggered arrangement for in-line arrangement; remove flue slagging and fouling, increasing gas flow area; reducing furnace wall leakage installation; spoiler or anti abrasion device etc..
少加熱面磨損情況的方式主要是有：才能削減生物質鍋爐加熱器端差，少高爐煤氣氣速;燃用特色煤種，才能削減蒸汽發生器生物質鍋爐高爐煤氣中飛灰占比;修改管制約束安裝方式，由錯列安裝轉為順列安裝;除掉油煙管道結渣及堵灰，擴大高爐煤氣流通不暢使用面積;少爐墻漏氣;安裝阻流板或防磨部件等。
Check the scuffing on the bore of the plunger sleeve of DSY electric pressure test pump. If the DSY type electric pressure test pump has passed the sealing test on the ST-990 or 3375375 tester, then the plunger sleeve is available. If the leakage is large, the piston and plunger sleeve must be replaced.
撿查DSY型電動三輪四輪試壓泵液壓泵套中孔上的劃傷。如若DSY型電動三輪四輪試壓泵已在ST-990或3375375測試器上借助了封口性測試，很液壓泵套是可以用的。如若滲漏量好大，就一定要改換液壓泵及液壓泵套。
