電熱水鍋爐http://www.nmsxkj.com/一旦爆炸將是十分嚴重的災害性事故，鍋爐爆炸按其發生原因可分為兩種類型，一是超壓爆炸，一是爐膛燃爆。那么電熱水鍋爐爆炸主要有哪些原因呢？

1、設計制造原因
選材不當、受熱面布置不合理、水循環設計有偏差、焊接結構設計不當、安全附件選用不當、計算或選用方法錯誤等。設計制造方面的缺陷如材質不良、焊縫有缺陷、組裝方法不當等造成了鍋爐的先天不足，是安全運行的隱患，只能通過嚴格的檢驗來發現。對重大隱患應通過設備改造來消除，對于難以消除的一般缺陷應通過定期的檢查檢驗對其狀況進行監視，避免其進一步發展，存在嚴重隱患時應停止鍋爐的運行。
Improper selection, heating surface layout is unreasonable, the water cycle design bias, improper design of welded structures, improper safety accessories to choose from, the choice of method to calculate or errors. Design and manufacturing defects, such as poor material, weld defects, caused by improper assembly of the deficiencies of the boiler, is hidden safe operation, can only be found through a rigorous test. Major hazards should be eliminated by equipment modification, for general difficult to eliminate defects should be monitored through regular inspection and

examination of their situation and avoid its further development, when there is a serious risk to stop operation of the boiler.

2、使用管理原因
電熱水鍋爐嚴重缺水運行或鍋爐局部水循環不暢，造成局部爐管干燒，爐管溫度過高超過屈服極限溫度而破裂爆管，或是鍋爐在嚴重缺水運行后，突然大量上水引發鍋爐壓力急劇增大，在局部瞬間超壓所致。因此，鍋爐嚴重缺水在運行中危險性極大，不僅會降低爐管的強度，減少爐管的壽命，甚至會引發爆炸，在運行中一定要盡力避免。
Electric water boiler or boilers run locally severe water shortages, poor circulation, resulting in partial tube dry, high temperature furnace tube temperature exceeds the yield strength and rupture burst pipes or boilers in operation after a serious water shortage, caused by a sudden a lot of Sheung Shui boiler pressure increases rapidly, due to pressure over the local moment.Therefore, a serious water shortage in the boiler running great danger, not only will reduce the strength of the furnace tube, reducing the life of the furnace tube, and even lead to an explosion in the operation must try to avoid.

3、電熱水鍋爐http://www.nmsxkj.com/檢修是鍋爐管理中的一個重要環節，該類原因包括安全附件失修、材料代用錯誤、爐管內異物堵塞等。檢修中造成的隱患在運行中很難發現，因此，必須在檢修管理中加以預防，包括制定詳細的檢修計劃、施工用料的嚴格管理、對進入鍋筒作業采取適當的防范措施等。
Electric water boiler boiler maintenance is an important part of management, such disrepair reasons, including safety accessories, material substitution errors, such as the inner tube blockage.Overhaul risks caused by running hard to find, therefore, must be prevented, including the development of a detailed maintenance plan, construction materials strict management to take appropriate precautions, such as entering the drum work in maintenance management.
