熱風爐結成水垢後都有哪些危害？怎麼預防？

由於水垢的導熱性很差，其導熱系數僅是鋼的導熱系數的幾十分之一至數百分之一，所以蒸汽熱風爐結垢後就會嚴重阻礙傳熱並引起下列危害：（如果您想知道什麼是水垢，它又是怎樣形成的請參考《詳解熱風爐設備使用中產生水垢的四種原因》）
Because of the poor thermal conductivity of scale, its thermal conductivity is only one-tenth to one-hundred of that of steel, so scaling in steam hot blast stove will seriously hinder heat transfer and cause the following hazards: (If you want to know what scale is, how it is formed, please refer to "Explaining the middle production of hot blast stove equipment in use" Four reasons for scaling (1)浪費燃料 蒸汽熱風爐和熱水熱風爐結垢後將嚴重影響受熱面傳熱，降低熱效率，減少蒸汽出力，增加燃料消耗，由於油、氣價格高，因此燃油、燃氣蒸汽熱風爐結垢後造成的浪費和損失將大大高於燃煤蒸汽熱風爐。
(1) Scaling of waste fuel steam hot stove and hot water hot stove will seriously affect heat transfer on heating surface, reduce thermal efficiency, reduce steam output and increase fuel consumption. Because of the high price of oil and gas, the waste and loss caused by scaling of fuel and gas steam hot stove will be much higher than that of coal-fired steam hot stove.
(2)影響安全運行 受熱面結生水垢後，金屬的熱量由於受水垢的阻礙而難於傳遞給鍋水，致使溫度急劇升高，材料強度顯著降低，從而導致金屬過熱變形+嚴重時將造成鼓包、裂縫、甚至爆破等事故。
(2) After scaling occurs on the heating surface affecting the safe operation, the heat of metal is difficult to transfer to the pot water due to the obstruction of scaling, resulting in a sharp increase in temperature and a significant decrease in material strength, which will lead to accidents such as bulging, cracking and even blasting when the metal is superheated and deformed seriously.
（3）破壞水循环 如果蒸汽熱水熱風爐內水管內結垢，就會減小流通印花地坪截面積，增加水的流動阻力，破壞正常的水循环，嚴重時還會完全堵塞管道，造成爆管事故。
(3) Destruction of water 环氧地坪circulation If scaling occurs in the water pipe of the steam hot-water hot-blast stove, the flow cross-section area will be reduced, the flow resistance of water will be increased, the normal water circulation will be destroyed, and the pipeline will be completely blocked in serious cases, resulting in pipe explosion accident.
(4)縮短熱風爐壽命 熱風爐結垢後還會引起垢下腐蝕等危害。另外，有些體積小、結構緊湊的燃油燃氣熱風爐， 一旦結垢極難清除，嚴重時其好采用挖補、割換管子等方法。上述這些危害都將大大縮短熱風爐的使用壽命。
(4) shortening the service life of hot blast stove and scaling down the hot stove will cause corrosion. In addition, some small, compact oil-fired gas hot stoves, once the scaling is extremely difficult to remove, when serious, it is better to use digging and repairing, cutting pipes and other methods. All these hazards will greatly shorten the service life of hot stove.
