Frequently Asked
Questions |
|
How is
the energy recovered? |
|
The air at atmospheric
pressure contains a base level of energy.
The compression increases the air pressure
and raises its temperature, and therefore
the available energy. In order to maintain
the compressor tolerances, the excess of
heat is removed via
the air or oil cooling system while the
compressed air is cooled down to make it
suitable for the intended use.
Using a heat exchanger it is possible to
extract this energy and transform it into
useful work reintroducing it into the
process for
heating air or process water. |
|
Where do
the savings come from? |
|
The main direct savings come from a
reduction in the amount of external fuel
sources used during the application process.
Besides, additional savings can be expected
from a reduction on maintenance costs of
associated firing fuel equipment (fans,
burners,
ducts, ovens, etc…) or improvements on the
overall efficiency on other compressed air
equipments (compressors, regeneration
dryers, etc…).
Potential savings are dependent on the load
cycle of the compressor, the cooling
mechanism and the application given to the
recovered heat. |
|
What can
be the typical applications for the
recovered heat? |
|
The heat recovered can be used for
pre-heating water or for heating air
providing a wide range of applications that
can be grouped
according to the duty or use cycle.
Recovered heat can be used for basic
stationary and intermittent use (normally
2000 to 3000 h/yr) such as:
supplemental space heating, general heating,
hot water for showers, toilets, laundries…
Or used directly in the process in a
continuous duty (normally 6000 to 8000 h/yr)
such as:
industrial drying, preheating aspirated air
for oil burners, central water heating,
makeup air heating, water preheating for
boiler
systems, industrial cleaning processes,
plating operations, heat pumps, laundries,
or any other application where hot water is
required.
Recoverable heat from a compressed air
system is not however, normally hot enough
to be used to produce steam directly. |
