Boiler Water Treatment - Industrial & Process
Applications
Boiler Water Treatment - In this short paper we
take a brief look at industrial boiler
water treatment and the management of steam boilers from an
industrial perspective. We examine some of the problems that can
occur when steam boilers are used in industrial and process situations.
We also look at solutions to the problems that arise with steam
boiler systems, specific products and where they are used, how these
solutions are applied, and more.
What is steam?
Steam is vaporised water, being part gas, part
liquid. Steam itself is usually interspersed with minute droplets
of water in its liquid state, which gives it a white, cloudy
appearance. In industrial and process situations, steam is
often generated using water boilers that are heated to create
steam under controlled conditions. The energy generated is
then transferred and used in many different ways.
In nature, steam is produced by the heating of underground
water by volcanic processes and is emitted from hot springs,
geysers, fumaroles, and certain types of volcanoes. |

Steam is used as a heat transfer medium in several industries including
food, paper, process, chemical manufacture ...etc. In industry steam
is produced by water boilers, which come in all shapes, sizes, types
and pressures and the water within them likewise. This is what makes
the life of a water treatment specialist interesting....having to
deal with all the alternatives and know all the ways of treating
those alternatives.
Why is boiler water used?
Steam under pressure is at elevated temperatures, greater than
100C and therefore can be used to transfer energy to different parts
of a system. This energy can then be used to cook, create energy
for chemical reactions, heat water and a myriad of other uses. Steam
being "pure" water dissolves other materials into it very
easily and it is these other materials that cause problems requiring
treatments. Materials such as metals from the system, Oxygen and
Carbon Dioxide to name but a few.
What problems arise and how do they
occur?
There are several problems within a boiler system some of which
require chemical treatment or other mechanical means to overcome
them. The major problems are:
- Scale
- Corrosion
- Boiler Water Carryover
- Sludge Deposition
These can cause problems in all parts of the system starting with
the feed tank leading through the boiler and into the condensate
system. The problems arise from the quality of the water used within
the steam raising system and the manner in which the system is operated
and hence it is not only chemical issues that need to be addressed.
What happens if problems are not
treated?
In extreme cases is has been known for steam boilers to explode
causing much damage and even death. So it is for this reason that
strict standards have arisen on how to treat and maintain boilers
and associated systems. Then there are efficiency problem with excess
fuel being used to raise the steam or leaks causing loss of water,
chemicals and energy from the system. All of these issues are avoidable
with simple chemicals and good maintenance regimes.

How are Accepta's products applied?
All products are ideally dosed continuously using a dosing pump
and tank. For optimum consumption they should be linked to a water
meter on the feedwater to ensure they are only dosed when needed,
and not under or over dosed. Some products should be dosed to
the feed water, whilst others to the steam header depending on
product system and the site specific problems faced, please consult
Accepta for more details.
What are the benefits of using
Accepta products?
Accepta's products should be used as part of a planned maintenance
regime and help to optimise and extend the life of plant and equipment,
hence reducing operating costs to a minimum.
