9.
Adjusting Air Shutter
Decrease the air shutter opening until the maximum power unit output is observed.
Allow the TEG to stabilize between air shutter adjustments, approximately 15
minutes. Lock the air shutter in place once the maximum power has been reached.
When the power starts to decrease slightly, reverse the last air shutter adjustment.
This should be the optimum setting.
NOTE: Optimum air shutter adjustment results in a peak point in power. Any adjustments
from this point will result in a decrease of power. The power falls off quicker if the combustion
is fuel rich compared to fuel lean, therefore it is better to be slightly air rich.
10. Adjusting fuel pressure
a.
If the measured power is
ABOVE
the target setup power,
decrease
the fuel
pressure by 3.5 kPa (0.5 psi) increments
b.
If the measured power is
MORE than 10 Watts
BELOW
the target setup
power, increase the fuel pressure by 3.5 kPa (0.5 psi) increments
c.
Allow the TEG to stabilize for 15 minutes between power measurements and
adjustments.
WARNING: Under no circumstances should the fuel pressure exceed 97kPa
(14psi) for Natural Gas, or 172 kPa (25psi) for Propane . Do not adjust fuel
pressure to achieve power greater than the target set up power.
11.
Re-adjusting Air Shutter
a.
Decrease the air shutter in increments of 5% to 10% and allow the TEG to
stabilize for 15 minutes between power measurements and adjustments. This
will cause the power to increase between adjustments.
b.
When the power starts to decrease slightly, reverse the last air shutter
adjustment. This should be the optimum setting.
NOTE: Optimum air shutter adjustment results in a peak point in power. Any adjustments
from this point will result in a decrease of power. The power falls off quicker if the combustion
is fuel rich compared to fuel lean, therefore it is better to be slightly air rich.
12.
If the measured power is still ABOVE the target setup power, reduce the fuel pressure
to reach the target power. This will leave the combustion slightly air rich as desired.
NOTE: Incorrect air shutter setting may result in power loss, unburnt hydrocarbons, and/or
carbon monoxide emissions greater than 50ppm. Soot may be visible on the exhaust and
rain cap.
3.4 LEAVING THE SITE
1.
Make sure the TEG performance is as required for the load and that the TEG is
operating normally.
2.
Make sure the Customer Load circuit breaker is in the “ON” position.
3.
Close the main electrical panel lid.
4.
Replace the pyramid stand panels using the 1/4 turn fasteners (1/4 turn clockwise).
5.
Ensure there are no combustible materials within 46 cm (18 inches) from the TEG.
