电蒸汽锅炉改造的原则
1、改造锅炉要能适用当地燃料，以提高热效率为主要目的。
Local transformation can be applied to the boiler fuel to the primary purpose of improving the thermal efficiency.
2、对没有改造价值，结构落后，效率很低，环境污染严重的旧式锅炉及旧式铸铁锅炉要坚决淘汰。
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、锅炉改造要符合安全监察规程有关条例，并根据本单位实际情况，不要盲目套搬别人经验。
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.
电蒸汽锅炉的技术改造的主要措施
1、砌筑适当形状的炉拱，以提高预热段温度和合理组织炉内气流。
Suitably shaped masonry arch furnace to raise the temperature and the rational organization of preheating furnace airflow.
2、改进燃烧设备。
Improved combustion equipment.
3、改进燃烧方式。
Improved combustion.
4、鼓风、引风机采用变频调速技术。
Blast, fan frequency control technology.
5、加装省煤器。
Installation of economizer.
6、加装锅炉管束。
Installation of boiler tubes.
7、改变炉膛辐射受热面。
Change furnace radiant heating surface.
8、改进气流对受热面的冲刷。
Improved airflow for heating surface erosion.
9、减少各门孔、墙缝的漏风。
Reduce each door opening, The gaps of air leakage.
10、加强炉体保温。
Strengthen the furnace insulation.
