The Fulton EFS Electric Flash Steam Boiler is a compact, fully automatic, self-contained steam
raising unit, specically designed to meet the requirements of applications requiring a short period
high demand steam supply.
A heated feedwater tank is available as an option, the purpose of which is to reduce the level of
non-condensable gases (NCG’s) in the steam as required by HTM* 2010 and to limit the
temperature and pressure drop within the boiler when feedwater is introduced.

SECTION 2 - INSTALLATION
2.1 GENERAL
2.2 SITING
2.3 WATER SUPPLY
The installation of the Fulton EFS Electric Flash Steam Boiler should be carried out by competent
personnel in accordance with all relevant safety regulations. It is the responsibility of the installer to
ensure that these regulations are complied with.
The Fulton Electric Flash Steam Boilers are designed to provide short term peak steam loads up to
three times the boiler steady state output.
This is achieved by providing the boiler with a very large pressure vessel, which acts as a combined
boiler and steam accumulator. As is the case with all accumulator applications the peak load must be
followed by a dwell/low load period to allow the accumulator to recharge back up to full pressure.
When a peak load which exceeds the normal output occurs, the boiler pressure falls releasing
energy in the form of ash steam to satisfy the peak load.
Note: To enable this to happen it is essential that a steam pressure reducing valve is installed in the system, and
that the boiler steam pressure control is set at the boiler maximum operating pressure of 10.34 barg.
!
WARNING
At all stages of operation the boiler will generate high temperatures,
which will be transferred to the boiler and the boiler ttings. Great
care must be taken to avoid any chance of receiving burns when
working on or near the boiler.
The boiler should be sited in dry surroundings on a level base as close as possible to the steam
using equipment.
Take note of the dimensions given in Section 5 and ensure there is sufcient room around the boiler
to allow for the connection of all services and to enable the maintenance engineer to gain access to
all parts of the boiler.
The quality of the water used in the boiler will affect the life of the elements and it is strongly
recommended that a competent water treatment supplier be consulted prior to the installation of the
boiler. Water should be treated to obtain the values quoted in Section 5.3 Recommended Water
Conditions.
Note: Elements damaged due to adverse water conditions cannot be replaced under guarantee. In order to
take a boiler water sample safely it is advisable to t a Water Sample Cooler which is not supplied as standard.
CAUTION
WATER SOFTENER and CHEMICAL TREATMENT
The chemicals required to operate the water softeners and
chemical treatment plants CAN BE SUPPLIED by Fulton Ltd.
It is the responsibility of the operator to ensure adequate supplies
of chemical are available at all times (including commissioning).
Costly repairs could be required should the plant operate without
chemicals or the wrong dosage of chemicals.
