Natural electric steam boiler
Electrically heated high-pressure steam generator based on the natural circulation
principle without forced circulation pump necessary. Therefore this steam generator
can only be operated in a hermetically closed steam-condensate circuit and should be
filled with demineralised- or distilled water acc. TRD 611 exclusively.
Due to given physical conditions the boiler has to be of vertical design.
Our NDK pressure part is formed by vertical pressure tubes in which the electro
heating flanges are installed. Pressure tubes lead into a joint steam header
and are connected in upper part by condensate lines. The tube-system is stress-free
mounted into a flue gastight boiler casing made of welded steel sheets and painted in RAL colour.
A solid base-frame construction allows to place the boiler on
a plain pressure-proof floor without requiring any special foundation.
Each generator is provided with high-quality thermal insulation material covered by structured aluminium sheets.
The design of our steam generator as well as used materials and manufacturing procedures
are in accordance with TRD-regulations (technical rules for steam boilers).
Consequently all welding fulfil the requirements of DIN EN ISO 5817.
The boiler will be delivered with a certificate of German TÜV authorities.
