SENs can prevent molten water from re-oxidation, they are divided into internal installed type and external installed type according to the difference of the structure
1、 The flage adopts compound materials, better anti-corrosion property, and also easy for flow control.
2、 The body adopts Al -C materials with perfect anti-thermal shock property.
3、 Al-Zr-C compound materials has perfect anti-slag properties.
4、 It adopts anti-corrosion inner layer, decreases the expanding speed of the inner hole of the nozzles, increases the service life.
5、 Insulating fiber keeps the temperature effectively and prevents molten water from condensation.
