Advantages of tubular boilers in comparision
to water space boilers
Quick steam generators are designed as single
tube forced circulation boilers. They have
significant lower water content than water boilers with the same thermal
Therefore the quick steam generators have the following advantages:
The disadvantage of lower thermal storage can
be compensated by installation of a steam accumulator.
- A separate boiler house is not neccessary
in most cases.
- Lower weight - erection in working areas
is possible, without special foundation.
- Quick steam generators reach their full steam
output within minutes without wasting energy.
- When operating with life steam - no condensate
return - the quick steam generator can be
equipped with simple and cheaper treatment units. Due to the design there's
of the treatment feedwater. The remaining humidity of 5% and the dissolved
separated by the water steam separator.
- Erection in containers
as mobile "stationary boiler" with
entire equipment is possible.
- In case of damage, the tube system can be
simply changed at site, this means that the most
important part of the boiler can be replaced. Water room boilers can't be
repaired but only
Technology and Definition
The term "quick steam generator" acc.
TRD 001 is used for steam generators or boilers with "forced
circulation", in TRD 401 they are also described as "flow heating
boilers". Flow heating boilers do have
no defined water level.
Typical Fields of Application
- Chemical Industry
- Industry of Building Materials
- Breweries and Vineries
- Laundries and Dry Cleaners
- Textile Industry
- Canteen Kitchens
The HSK Quick Steam Generators System GEKA Heat
Technology are single tube once-through (forced
circulation) boilers. The burning chamber consists of a cylindric tube system
where the gas or oil burners
can be operated without contact to the inner surface. Behind this first pass
a second pass (convection
heating surface) is mounted coaxial to the first, consisting of a second cylindric
tube system. The tubes
forming the heating surface are therefore built in series. The water is pumped
into the tubular system and
is nearly completely vaporized by reaching the steam exit.
This kind of boiler is called Benson-Boiler and
has been patented in 1904 (torpedo boat boiler).
The first GEKA-Quick Steam Generator
type SDE-150 was manufactured in 1957 in Berlin and was
operating properly in a laundry for more than 35 years.
Since then the construction was improved permanently and conformed to customer's
We therefore dispose of a modern and wide range of quick steam generators with
up to 8.000 kg/h.
We're also producing the world's smallest quick steam generator called "MINI
50" with a steam output of
50 kg/h. This MINI 50 is an economical alternative to electric steam generators,
that need high electrical

Calculation of construction, selection of materials
and equipment acc. TRD - german technical
regulations for pressure vessels or acc. PED 97/23/EC.
Production and pressure test under supervision of
calculations and acceptance of construction by foreign supervision
organizations on request.
Heating by means of light
fuel oil, natural gas or dual fuel with type tested standard burners,
For the operation of quick steam generators proper
feedwater has to be used.
The feedwater must be according to the TRD or VdTUEV-Instructions.
