Steam Generator - Vertical type
HIGH EFFICIENCY - LOW CO2 EMISSION
Steam generators often comes
with very high efficiencies equal low fuel consumption and low CO2 emission.
But special request on extra high efficiencies and extra low CO2 emission
can be offered as a part of our general customized solution features. It
costs a little more, but the overall cost are normally lower - and the
environmental issue should also been taken into account.
Additional efficiency can be obtained by using an
economizer (optional extra).
LOW NOx
The steam
generators are prepared with combustion chambers for ensuring Low NOx when
choosing an appropriate Low NOx burner. This design also offer high efficiencies.
More green solution, often a request. The long term extra costs are very
often modest due to the higher efficiency.
|
NOTE! Without
a suitable combustion chamber design, no Low NOx burner can
ensure environmental values with regard to NOx emissions - the boiler design
is essential to ensure Low NOx. |
EXTENT OF DELIVERY
Steam generators can be
delivered in horizontal execution (with low height), or in vertical execution (occupying
limited floor space). They are delivered insulated with stainless steel cover sheets and
complete with burner, armatures, instrumentation, safeties and a control panel - and with
full documentation including necessary certificates.
All steam generators are
carefully checked, controlled and function tested prior to dispatch from the
workshop.
|
CONSTRUCTION
The steam generators heaters are made
with coils made of seamless tubes, where the feed water is preheated and evaporated during
the flow through these. The heat is transferred to the water/steam mixture as radiant heat
in the combustion chamber, where the inner cylindrical tube coil and a flat tube coil
forms the chamber wall and the bottom respectively. Consequently refractory concrete is
avoided. The combustion gasses are hereafter cooled in the outer convection part, as the
gasses pass the space between the two tube coils. The thermal design ensures a modest
volume of steam relative to the size of the heater, and allows unlimited thermal expansion
due to the high temperatures. All TT BOILERS steam generators and steam boilers are
designed and equipped according to German TRD boiler regulations and Danish boiler
regulations and corresponding EN-norms.
DT steam generators are made in carbon steel,
but also different grades of
stainless steel.
Making the Steam Generators
SPECIAL DESIGNS
Beside the standard execution the
steam generators can be delivered in e.g. following variations:

the 'R&D Workshop' |
BURNERS
As standard the heaters are provided by
international recognized and only high quality burner brands - for natural gas, light fuel
oil, heavy fuel oil and combinations (dual fuel). This include Low NOx
burner designs. Demands for special burner designs can
be fulfilled and adapted in the heater design.
STEAM
GENERATORS
OR STEAM BOILERS ?
There are indeed some major differences
between a steam generator and a classic 3-pass fire-tube steam boiler.
Advantages and disadvantages
are present depending on the actual circumstances.
Read more about different
type of steam boilers and about making the right choice on selecting the
Correct
Type of Steam Boiler. AB&CO offer both types and have
no preferences in advising in favour of either type.

PRODUCTION OF CLEAN STEAM
Steam
generators are also delivered for production of clean steam for food
industry, pharmaceutical industry, electronically industry etc. |

Sanitary steam
(clean steam) for food applications
are provided by a steam generator made in high grade
stainless steel. The photo above shows a unit
for Rolls Royce in UK which should also have other
special features such as steam of 190 barg / 350°C.

For
pharmaceutical industry a special grade of high quality sterile steam is used
- so-called pure steam. The photo above shows steam generators with
capacity of 300 kg/h and 600 kg/h - with reboiler, grinded and
polished internally.

electrical heated models can be provided on request.
For using above table you should choose the size above your required
heat capacity, to get the dimensions and weight for the unit.TABLE VALUES · Presumptions:
The below stated values for heat capacity and fuel consumptions are based on
80°C
feed water temperature, 7 bar steam pressure, 90% efficiency and normal European quality
light fuel oil (LCV=42 MJ/kg) and natural gas (LCV=40 MJ/Nm³) |

CONTAINERISED STEAM BOILER
ROOM An
option is the container solution, comprising all
equipment for ensuring a efficient steam production.
Containerized solutions are used widely as an fast and economical way to
establish steam up to 2400 kg/h.
It can be used as an emergency steam
back-up, when a steam supply fails and a fatal situation occurs. With a
container solution you can rapidly be "on-steam" again.
This solution is used
for end-user of steam, but it is certainly also as an attractive business opportunity
to buy these for renting out
- and thus offering the above services to end-users.
Steam generator boiler are also available
