1. General

The SCHNEIDER Steam Generatorof Series HDO-Eand the SCHNEIDER Hot Water Generator

of Series HWO-Eare designed as electrically heated boilers for special installation and operation

conditions. Operation and working mode of HDO-Eand HWO-Eboilers are in compliance with the

operation and working mode of all conventional steam or hot water generators. However, due to

the fact that there are no flue gas passes in the HDO-Eand HWO-Eboilers, the dimensions are

significantly smaller even though the water content and capacity is the same.

2. Design FeaturesSince the HDO-E and HWO-E are shell boilers, the same technical regulations apply for design

and manufacturing as for the SCHNEIDER Three Passboiler of series HDOand HWO.

The HDO-E / HWO-E boiler is designed as a horizontal pressure vessel with internal electrical

heating packs. The shell end plates are of torispherical design without any gusset stays or tie

rods and hence avoiding the well known problems with gusset stays and tie rods. Another advan-

tage of the torispherical end plates is that the circumferential welds can be 100% x-ray checked

which is of huge benefit in comparison with regular flat end plates.

One end plate is equipped with two (2) neck flange nozzles to install the electrical heating packs. In

addition these neck flange nozzles are used for inspection and cleaning of the boiler.

3. Advantages and Main Features

Lowest possible dimensions in comparison with conventionally heated and designedboilers of same capacity.

Applies ideally to limited spaces due to compact design.

No lines connected for fuel supply and flue gas outlet.

No fuel storage tanks needed.

No environmental pollution or explosion risk as existing when utilizing liquid or gaseousfuels.

Minimized operation costs /service, maintenance, repair in comparison with convention-ally heated boiler.

Less leakage possibilities of faulty welding in comparison with conventionally heatedboilers.

72 hour operation without permanent supervision because of state-of-the-art self con-trolling and redundant electronic safety systems.

Prefabricated and preinstalled package boiler including electrically installed control box,feed pumps, auxiliary fittings etc. delivered on site ready for operation.

4. Range of Application

The HDO-E / HWO-Eare used where conventional boilers cannot be installed because of limited

space, restrictions by regulation, hygienic constraints or economic reasons:

in the pharmaceutical industry,

in hospitals,

in the ship building and off shore industry,

as emergency units for conventional boiler in any industry.

5. Fabrication and Equipment

Design and fabrication of HDO-E / HWO-E is in accordance with the German Technical Regulation

for Steam Boiler (TRD) respectively Euro-Norm EN-12953 in connection with the Pressure Vessel

Directive DGRL 97/23/EGas stationary boiler (land-based boiler).

In addition, boilers of series HDO-E / HWO-Ecan be delivered classified as marine boilers in ac-

cordance with the regular classification standards such as GL Germanischer Lloyd, LR

Lloyds Register, DNV Det Norske Veritas and BV Bureau Veritas. The fabrication is su-

pervised and monitored by representatives of the respective authority.

Boiler equipment parts and systems are only used when they are certified by the respective classi-fication authorities.

Depending on the application, boilers of series HDO-E / HWO-Eare delivered with diverse equip-

ment determined by the following factors:

level of automation / operation without permanent supervision,

mode control / supervision,

operational safety / availability and reliability.
