When there is a heat differential between its ends
No, a thermocouple does not convert chemical energy into electrical energy. It generates electricity by using the Seebeck effect, which is based on the temperature difference between two different metals. The thermocouple produces voltage directly from heat.
A thermocouple produces electrical energy by utilizing the Seebeck effect, which generates a voltage when there is a temperature difference between the two junctions of dissimilar metals in the thermocouple. This electrical energy can be used to measure temperature or power electronic devices.
It doesn produce electricity. It uses electricity and shows magnetic properties.
The thermocouple is normally regarded as a high-impedance voltage source. As such, the voltage across it due to temperature is sensed, and processed by an amplifier stage that doesn't rely on it to supply appreciable current. You should think of it as a constant voltage source with a high internal resistance.
Windmills produce electricity by harnessing the kinetic energy of the wind. The wind causes the blades of the windmill to rotate, which in turn drives a generator to produce electricity.
No single piece of metal will produce electricity when heated. You will need two different metals, mechanically touching. When the join between the metals is heated, it will produce electricity, dependant on the metals used. This is known as a 'thermocouple'.
These are called "thermocouples".http://en.wikipedia.org/wiki/Thermocouple
A thermocouple is used to measure electricity in industrial situations. The K type thermocouple is the most common one as it is inexpensive and can be used to test in a large number of situations.
To test a thermocouple on a water heater, you can use a multimeter to measure the voltage output. Disconnect the thermocouple from the control unit and place the multimeter probes on the thermocouple terminals. A functioning thermocouple should produce a voltage reading within the expected range. If the reading is outside this range, the thermocouple may need to be replaced.
Use a thermocouple.

Batteries do not produce electricity, they only store electricity.
To produce 230 volts using thermocouple action, you would need to connect multiple thermocouples in series to add up their voltages. Each individual thermocouple generates a small voltage, typically in the range of millivolts, so by connecting them in series you can sum up their voltages to achieve the desired 230 volts. Keep in mind that the number of thermocouples needed would depend on the voltage output of each thermocouple and the overall design of the setup.

generators produce electricity via electromagnetic induction
If your talking about a pilot in a furnace or fireplace, then its because the gasvalve is powered by a thermocouple. The thermocouple is 2 dissimilar metals fused together, when heated it produces a small amount of electricity to hold the valve open.
Well, Many things can produce electricity. An easy way to produce electricity is to get a coil and pass a bar magnet through it.
