Thermoelectric Generator: A device that produces electrical power through the direct conver- sion of heat energy to electrical energy. Power Unit: The hermetically sealed portion of the generator that contains the thermoelectric materials and the cooling fins. TEG: A thermoelectric generator. Matched Load: A condition of load where: the load voltage of the generator is one-half of the open circuit voltage. the load resistance is equal to the internal resistance of the generator. Optimum Load: A condition of load where the power output of the generator is maximized. Precision Load: The precision resistor contained on the generator that provides the optimum load condition. The voltage across the resistor is defined as V and is used to analyze gener- ator electrical performance. Power Conditioner: A broad term used to describe an electronic device attached to the gen- erator output that converts, adjusts, limits or otherwise conditions power. Auto Shutoff: The 1120 generator is equipped with a thermocouple controlled solenoid valve that can be manually reset. In the event of extended flame failure the thermocouple output will be reduced sufficiently to release the solenoid and stop fuel gas flow to the burner.

Page 11: Theory Of Operation
If this junction is heated to a higher temperature than the other end of the wire, Figure1 TEG Design a voltage will exist across the cooler end. Further, electrical power will be delivered to a load placed in the circuit. This process will continue provided that the temperature difference is maintained. A TEG is a system which provides the means to maintain these required con- ditions. Figure 1 illustrates how this is accomplished in the model 1120 TEG. A thermocouple is formed by a P type and an N type thermoelectric element joined together electrically by a hot junction electrode. Adjacent thermocouples are joined together electrically by cold junction electrodes. Eighty thermocouples, each producing 84mV are connected in series so the power unit produc- es 120 Watts at 6.7 Volts and 18 Amperes.

Page 12: Physical Description
The burner operates at moderate pressures from 28 to 70 kPa (4 to 10 psi). The gas is expanded through an orifice and then flows through a venturi where it draws in air needed for combustion. The fuel flow is controlled by a pressure regulator and is adjusted by the operator to obtain the desired power output. In summary, the TEG produces electrical power when a temperature difference is maintained between the hot and cold junctions of the thermoelectric materials. The temperature difference, and therefore the amount of power produced, depends on the rate at which fuel is supplied to the burner. The operation of the TEG is simply the control of the fuel pressure to the burner which results in the desired power output. 1 .4 Physical Description Figure 2 shows the generator in its normal operating position.

Page 14: Electrical Output Characteristics
1 .5 Electrical Output Characteristics Figure 3 shows the electrical output characteristics of the Model 1120 power unit, which gives the power, current and voltage as a function of the load resistance. The TEG will operate at any load condition from short circuit to open circuit. Observe that the power goes through a broad maximum between 0.3 and 0.5 ohms. Rated power (120 Watts) can be obtained only if the load resistance is within this range. The graph is useful in determining power, current and voltage at various customer load conditions. Refer to the graph and consider the following example: You are installing a Model 1120 TEG at a gas wellhead to cathodically protect the well-casing from corrosion. You have measured and determined your total ground bed resistance to be 1.0 ohm. Find 1.0 ohm on the horizontal axis. Read vertically until intersecting the power, current, and voltage curves. Read horizontally to the vertical axis to determine the values of power, current and volt- age. Which are 106 Watts, 10.2 Amps and 10.3 Volts. 1.6 Ambient Temperature Effects The electrical output of the TEG is dependent on ambient temperature as shown in Figure 4. Observe that the power decreases as ambient temperature increases. Statement of Rated Power The Power Unit produces 120 Watts when operated at an ambient temperature of 20ºC. -

Figure 5. Ensure that the TEG is mounted in accordance with following notes: The TEG must be mounted with the fin duct in a vertical position. The air flow through the cooling fins must not be obstructed. The TEG should be mounted at a height sufficient to prevent direct flooding or heavy snowfall from interfering with the flow of cooling or intake air. When the generator is installed near a building, field experience has shown that the best locations are on the roof or on the windward side, with a minimum distance of 3.0 meters (10 feet) from the building. Be sure that the TEG location relative to buildings and fuel containers are in accordance with local regulations. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -

Page 25: Start-Up Data Sheets
Start-up Data Sheets are provided at the back of this manual to assist you in setting up the TEG properly. During set up you will be asked to record data on these sheets so keep them available. It is recommended that a Data Sheet be used each time the TEG is started. They are valuable for future reference. If additional sheets are needed they can be duplicated. 2 .3 Starting Generator Perform the following steps (see Figure 10): 2.3.1 Turn on fuel. Loosen the lock nut on the fuel regulator. 2.3.2 If required, correct the factory set fuel pressure for the elevation as per Figure 9, Change in Fuel Pressure Vs . Elevation . 2.3.3 Adjust the air shutters to slightly fuel rich from the factory set position. Note that the air shutters should always be adjusted equally in small increments. 2.3.4 Set the “Power Switch” to set up position. 2.3.5 Set the “Output Voltage Adjust” to middle position.

Page 26: Heat Up To Rated Power
If V is greater than 6.5 volts, the fuel pressure is set for more than rated power. Reduce the fuel pressure by 9.8 kPa (1.4 psi) at this time, see Figure10 and Figure 13. WARNING: To prevent damage to the TEG do not allow the V to exceed 7.1 volts at ambient temperatures above 24ºC (75ºF). 2 .6 Versus Power the voltage across the precision load, is a measure of power. The value of the precision load (0.387 ohms) is selected to provide the optimum load condition for the TEG. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -
Page 27: Determining Required V Set
The power is 120 watts. Locate 120 watts on the horizontal axis. Read vertically until intersecting the curve. Read horizontally to the vertical axis to determine V Which is 6.8 volts. 2 .7 Determining Required V This heat up period is the ideal time to determine the V is based on set up power as follows: SET UP POWER from Figure 4 from Figure 12 Set up power is found by adjusting the desired power for ambient temperature. V is deter- mined from set up power as shown in Figure 12. Estimate the maximum ambient temperature expected at the side and record on the start up data sheet as Item 3. Measure or estimate the present ambient temperature and record as Item 4. If rated power or maximum allowable power is desired: Use the information in Figure 4 and the procedures in section 1.7 to determine the cor- responding set up power and record as Item 5. Use Figure 12 to determine the related V and record as Item 6. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -
Page 28: Fuel And Air Adjustment
Figure 12 V Vs Set up Power If less than rated power is desired: Determine the desired power output. Determine the corresponding set up power by adding 0.3 watts to the desired power for each ºC difference between the present and maximum ambient temperatures. Refer to Figure 12 to determine the related V and record as Item 6. 2 .8 Fuel & Air Adjustment After the TEG has been operating for one hour, V should not be changing with time. The readings on the start up data sheet at 40 and 60 minutes should not differ by more than 0.2 volts. When you are satisfied that V is not changing with time, compare the measured value of V with the required V , Item 6. Proceed with air shutter adjustments to optimize the burn- er first (section 2.9) then adjust the fuel pressure as required (section 2.10).

Page 29: Air Shutter Adjustment
In both cases fuel is being wasted. When the air shutter is at its optimum setting (neither of above) the TEG is operating at maximum efficiency. NOTE: If available a combustion analyzer will facilitate rapid air shutter optimizing as you need not wait for V to change. Figure 13 shows change in V as a function of air shutter settings. Observe that V decreases more rapidly on the fuel rich side than on the air rich side. For this reason a fuel rich operation is to be avoided. Make initial adjustments of air shutters towards the fuel rich side by decreasing the air holes. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -
Page 30: Fuel Pressure Adjustment
Suppose the measured V is 6.5 volts, but 6.7 volts or a change of +0.2 volts is required. Locate the ±0.2 volts on the vertical axis and read horizontally until intersecting the curve. Read vertically down to the horizontal axis and find the required change in fuel pressure. Which is 5.5 kPa (0.8 psi). You must increase the fuel pressure by 5.5 kPa or 0.8 psi. Suppose the measured V is 6.8 volts and that 6.5 volts or a change of -0.3 volts is required. Locate -0.3 on the vertical axis and read horizontally until intersecting the curve. Read vertically down to the horizontal axis and find the required change in fuel pressure. Which is -8.3 kPa (-1.2 psi). You must decrease the fuel pressure by 8.3 kPa or 1.2 psi. 2.10.1 Use the following procedures to make the adjustment in fuel pressure: Global Power Technologies 1120 - Class I, Division 2, Group D, T3... - Page 31 Figure 14 Fuel Pressure Vs V Record V after a minimum of one hour of operation as Item 7. Determine the required change in V by subtracting Item 7 from Item 6 and record as Item 8. Record the fuel pressure as Item 9. Determine the required change in fuel pressure from Figure 14 and record as Item 10. Determine the new fuel pressure by adding Item 10 to Item 9 and record as Item 11. EXAMPLE: Item 9 = 37.9 kPa (5.5 psi) Item 10 = 2.1 kPa (0.3 psi) New Fuel Pressure = 35.8 kPa (5.2 psi) Adjust the fuel pressure to the value in Item 11. Close the cabinet doors and record the time.

Page 32: Applying Customer Load
When the measured and required values of V are in agreement, the TEG is ready to switch to operation mode. 2 .11 Applying Customer Load The TEG is now operating at the required power output. If this is a single TEG system, it is ready to connect to the customer load. If there are multiple TEGs ensure that all units are ready before proceeding. If station batteries are present, measure and record their voltage. Batteries should be fully charged; if they are too deeply discharged, the 1120 TEG will not charge the station battery. Set power switch to “Run” position, see Figure 10. The TEG “normal” light should come on. Adjust the voltage control to the desired operating voltage plus 0.7 volts using the Output Voltage Adjust dial on the electronics box and the reading on digital panel meter. If a multiple TEG system is in use, ensure that all outputs are equal. Note: The TEG incorporates a protective series diode. The output voltage will drop 0.7 Volts from the no load to loaded condition. Push the red “Meter Select” button to read the current. Connect the customer load via disconnects mentioned in Electrical Connection section 1.12. The TEG “Normal” light should remain as a steady glow, if the lamp dims or the output voltage drops significantly, the TEG is being overloaded. Ensure that the load is no more than 100 watts at 24-30 volts. In multiple generator systems ensure that all outputs are set the same.

3 .3 Burner Assembly: See Figure 25 The burner assembly consists of the burner components, the heat exchanger, and flame arres- tors, air intake and exhaust . This assembly performs several functions. The orifice introduces fuel at a predetermined pressure to the burner. This fuel flows through the venturi tube and the venturi effect causes air to be drawn in through the intake flame arres- tors. The air shutters regulate the combustion air quantity. Thus fuel and air are mixed in the venturi tube and passed through the burner screen to the back of the combustion chamber, where it is ignited and burned to produce the operating temperature required. See Figure 1, section 1.3. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -

14 kPa (2 psi). This switch on closing applies 2 VDC and power to the ignition system dis- cussed above. This feature gives auto ignition at start up and a short term auto re-ignition in the event of a flame out, due to blow out, short term loss of gas, or short term severe hazard condition. The fuel is next fed to the flexible fuel line and then to the orifice. The flexible fuel line is stan- dard, however the orifice is unique to the type of fuel used, natural gas or propane. 3 .5 Igniter Housing Assembly: See Figure 28 . The ignitor housing assembly consists of a junction box housing, the associated fittings and the high voltage ignitor module. Also it contains the ignitor electrode assembly, the interconnect cable and the mounting connector. Global Power Technologies 1120 - Class I, Division 2, Group D, T3... -

3.7.1 Electronic Housing: This box has been designed to meet the requirements of Class I, Division 2, hazardous areas. It also performs as a heat sink capable of dissipating the full output power of the TEG when in a set up or no load condition. 3.7.2 Precision Load: Two 0.75 ohm, 50 watt resistors connected in parallel (resulting in 0.375 ohm) as well as their associated wiring, which when switched to the power unit, give us a precision load resistance of 0.387 ohm (approximately), provide the optimum load condition for the TEG. This precision load is used for adjusting the TEG and eval- uating its performance. A load voltage of 6.87 volts would give 120 watts from the TEG.

The 20K trim pot is used to set the gain of the OP-AMP to limit the current at 15 AMPs. This is factory set and should not be adjusted by field personnel. 3.7.5 Voltage Sensing Relay Circuit (VSR): Refer to Figure 19. The VSR circuit uses a LM311 voltage comparator to operate the relay K1. The 2.5 Volt level created by the LM285Z 2.5 voltage reference is used as one input while the output from the tap of the 10K trim pot is used as the other. The LM317T is configured as a 10.0 volt regulator to provide a stable voltage for the relay and comparator to operate with either a 12 or 24V output voltage. The 10K trim pot is set so that the relay is energized for normal opera- tion, and de-energizes for an alarm. The relay contacts are brought out to the edge of the main PCB shown in Figure 30.
