cooling circuit. This water is then sent to a cooling
system, before it is re-injected into
the cooling circuit.
deNOx: elimination of Nitrogen oxides, NOx in short
form, from waste gases.
deSOx: elimination of Sulfur oxides, SOx in short form,
from waste gases.
Dry cooling system or air-cooled steam condenser:
used in the production of electricity, this system directly
condenses steam at the exit of the steam turbine, in
finned tube bundles cooled by the surrounding air.
EBIT: Earnings before interest and tax.
EBITDA: Earnings before interest, taxes, depreciation
& amortization and non-recurring items.
EMEA: Europe, Middle East and Africa.
EPC (Engineering, Procurement and Construction):
engineering firm.
Glossary
Air Cooler (or AFC): heat exchanger in which an often
corrosive liquid or gas, under high pressure and high
temperature, passes through special alloy finned tubes
and is cooled by air from a ventilator. Used mainly in
petrochemicals, and the Oil & Gas industry, but also
in the cooling of auxiliaries, for example water in the
steel industry.
APC: Air Pollution Control.
Bank Guarantees: guarantees given by a bank for a
certain amount and over a fixed period, when contracts are
made (sold) and executed. Principal categories: advance
payment bond, performance bond, and warranty bond.
Cooling System when referred to in the context of
power generation: in a traditional power plant generating
electricity, water is heated and transformed into high
pressure steam. This turns a steam turbine connected
to an alternator, which converts mechanical energy to
electrical energy. At the exit of the turbine, the steam is
cooled on a surface condenser through indirect contact
between the steam and cold water running through the
ESP: Electrostatic Precipitator, an electrostatic filter
that eliminates particles from the exhaust gases.
FRP: Fibre-Reinforced Plastic, used for example for
exhaust gas ducts in chimneys.
GRI: Global Reporting Initiative: international body
whose mission (at a worldwide level) is to provide to
organizations of any size, any location and any area a
reliable, credible and standardized framework for their
reporting in sustainable development.
Group or Hamon Group: the name for Hamon and
its subsidiaries in the sense of the Company Code,
article 6, 2°.
Hamon: the name of the limited company (under Belgian
law) Hamon & Cie (International) SA, with its head office
at Axisparc, rues Emile Francis 2, 1435 Mont-St-Guibert,
Belgium. The Hamon trade mark and logo (as it appears
on the back cover of this report) are protected in most
countries in which Hamon is established.
HRSG: Heat Recovery Steam Generator, used in
combined cycle power plants to generate steam from
the hot gas turbine exhaust.
Hybrid cooling system: combination of a wet cooling
system and finned tube bundles that slightly heat the
saturated humid air, in order to reduce the steam plume.
