Answers
to questions commonly asked about
The Eddy Draft Regulator |
When should the Eddy Draft Regulator BE
USED?
The EDR'S is applicable in any flue stack system which has an
excessive static flue pressure. "Excessive" means
negative flue pressure greater than the optimum suggested by the
equipment manufacturer, or which causes increased flue gas
velocity and excess air in the fuel/air ratio, resulting in heat
loss through the flue stack. Dampers, oxygen trim systems,
economizers, turbulators and other heat loss controls are not
disturbed by installing the EDR, but much of the function of
each is placed or superseded by the operating dynamics of the
EDR. |
Can the EDR cause any harm to
Equipment?
NO!! The EDR simply "tunes" the flue stack system for
optimum combustion and thermal performance. It does not change
the characteristic operations of the equipment, nor does it
exceed the manufacture's suggested combustion or venting
parameters. In fact, with the EDR, the equipment runs smoother,
burns cleaner and lasts longer. Heat exchanger surfaces and
combustion chambers require less maintenance and repair. Nothing
in the burner, pressure vessel, or basic equipment itself is
adversely affected. Less fuel is used per BTU output. Flue gas
temperatures are sometimes slightly decreased in power boilers
due to better thermal transfer, but in the majority of cases are
10% to 25% higher due to better fuel combustion and flue gas
heat retention. Therefore, flue gas condensation and acid
formation is eliminated. |
How much Energy can be saved with the EDR?
Savings will, of course, vary with the application. A brief test
of the equipment's "as found" operating conditions
provides the data needed to project an expected savings range.
Typical energy savings range from 10% to 30% in
atmospherically-vented equipment, and 5% to 20% in power-vented
equipment, depending on the "as found" combustion and
draft readings. Energy savings of even 2% or 3% are very
significant in large industrial boilers which consumes millions
of dollars in fossil fuels each year. Pollution reduction
achieved with the EDR will pay additional dividends for years. |
Is the EDR Approved?
There are many agencies, jurisdictions and governments from
which product "approval" or "acceptance" is
possible. Many have no policy regarding products such as the
EDR. Others request a "listing" by local or national
mechanical codes. The EDR meets ALL common codes related to
mechanical flue stack venting, and listings are possible. None
have been sought to date due to the simplicity of the technology
and its safety. |
Why isn't the EDR widely used if it is so
Effective?
The answer is simple. The EDR is patented only recently and is a
relatively little known technology to date. It is a unique and
fail safe answer to major causes of fossil-fuel heating and
process equipment inefficiency. As expanded marketing allows the
EDR to be widely introduced to the multi-billion-dollar
fossil-fuel heating and boiler industry, the EDR will certainly
become a commonly used and well established technology in the U.
S. and in all other industrialized countries of the world. |
Who can install the EDR?
The EDR is not a "do it yourself" technology. It must
be installed by a trained and certified heating and boiler
technician to ensure proper settings. |
