   The thermocouple sensor detects the heat from the pilot light and sends a signal to keep the gas valve open, but if the pilot light is extinguished, then the thermocouple will send a signal to the ...

   en.wikipedia.org/wiki/Bimetallic_strip

   In devices without pilot lights for ignition (as in most modern gas clothes dryers and some natural gas heaters and decorative fireplaces) the power for the contacts is provided by reduced household electrical power that operates a relay controlling an electronic ignitor, either a resistance heater or an electrically powered spark generating ...

4. Pilot light - Wikipedia

   en.wikipedia.org/wiki/Pilot_light

   The appliance efficiency of a gas-fired balanced flue local space heater in pilot light mode is almost equal with the appliance efficiency measured at the reduced power of the appliance, which efficiency is between 65–95% based on the low calorific value of the consumed gas, making part of the pilot light's energy consumption into useful heat.

5. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   As illustrated in the use of the thermostat above, all of the power for the control system is provided by a thermopile which is a combination of many stacked thermocouples, heated by the pilot light. The thermopile produces sufficient electrical power to drive a low-power gas valve, which under control of one or more thermostat switches, in ...

6. Gas stove - Wikipedia

   en.wikipedia.org/wiki/Gas_stove

   Gas stoves today use two basic types of ignition sources, standing pilot and electric. [21] A stove with a standing pilot has a small, continuously burning gas flame (called a pilot light) under the cooktop. [21] The flame is between the front and back burners. When the stove is turned on, this flame lights the gas flowing out of the burners.

7. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty ...
