電蒸汽鍋爐改造的原則
1、改造鍋爐要能適用當地燃料，以提高熱效率為主要目的。
Local transformation can be applied to the boiler fuel to the primary purpose of improving the thermal efficiency.  
2、對沒有改造價值，結構落后，效率很低，環境污染嚴重的舊式鍋爐及舊式鑄鐵鍋爐要堅決淘汰。
No value for the transformation of the structure behind, inefficient, polluting the environment and the legacy of the old cast iron boilers Boilers must be resolutely eliminated. 
3、鍋爐改造要符合安全監察規程有關條例，并根據本單位實際情況，不要盲目套搬別人經驗。
Boiler safety monitoring procedures to comply with the relevant regulations, and in accordance with the actual situation of the unit, do not blindly move sets the experience of others.

電蒸汽鍋爐的技術改造的主要措施 
1、砌筑適當形狀的爐拱，以提高預熱段溫度和合理組織爐內氣流。
Suitably shaped masonry arch furnace to raise the temperature and the rational organization of preheating furnace airflow.  
2、改進燃燒設備。
Improved combustion equipment.
3、改進燃燒方式。
Improved combustion. 
4、鼓風、引風機采用變頻調速技術。
Blast, fan frequency control technology.
5、加裝省煤器。
Installation of economizer. 
6、加裝鍋爐管束。
Installation of boiler tubes. 
7、改變爐膛輻射受熱面。
Change furnace radiant heating surface. 
8、改進氣流對受熱面的沖刷。
Improved airflow for heating surface erosion.   
9、減少各門孔、墻縫的漏風。
Reduce each door opening, The gaps of air leakage.
10、加強爐體保溫。
Strengthen the furnace insulation.
