| Without question energy conservation and the
environment are among America's most critical issues. Present
patterns of fossil fuel usage and waste will not only continue
to destroy our environment, but further our dependence on
foreign fuel supplies, which create economic hardship.
We at Draft Technologies LLC believe that we
have the single most comprehension solution to the heating
industry's fossil fuel inefficiency in the world today. The
technology is simple, fail safe, universally applicable and
effective in reducing consumption of natural gas, LP, gas,
(propane) and oil. While saving fuel (and therefore, money) our
product by its very design creates a cleaner, healthier
environment.
Combustion engineers agree that "stack
loss" (the wasted heat that escapes up the flue stack of
our residential, commercial, industrial and government
buildings) is the greatest heating industry contributor to air
pollution and energy loss.
Curbing stack loss is the
most direct route to energy efficiency and pollution control.
The technology offered by Draft Technologies
LLC does just that.
When heating equipment utilizing fossil fuel
is rated for performance in the laboratory, an ideal flue draft
is used in order to obtain the optimum output of the equipment.
The same equipment installed in the "real world", is
attached to a stack with a height that may range from several
feet to several stories. The stack is nearly always over-sized
with no provision for controlling flue draft. It is common for
heating equipment efficiency to plummet from 15 to 60 percent
between the laboratory and the real world conditions.
Economizers, preheaters, oxygen trim devices, turbulators and
damper systems are a few of the solutions that are used to add
percentage points to the efficiency ratings of boilers.
Barometric dampers attempt to address the flue
draft problem but achieve only partial results and waste
conditioned air in the process. Vent dampers close off the flue
on the standby cycle, but do nothing for the problem during the
run cycle. Oxygen trimmers are expensive, complicated high tech
devices subject to electronic failures, normally used only on
large commercial and industrial boilers. Users often disconnect
them out of frustration. |
