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 ...
Pilot lights were withdrawn because their continual small flame represented a waste of fuel. [1] Pilot lights required their own FSD, typically a thermocouple which held the valve open. [2] Regular testing of FSD is a part of routine maintenance for gas appliances. [3] Other safety devices may be fitted in addition to an FSD.
A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition ...
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.
Gas lighting in the historical center of Wrocław, Poland, is manually turned off and on daily.. Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas (town gas) or natural gas.
Heated enclosure packages are used to protect pipes from rain and ice build-up by keeping the pipes heated. The catalytic heater is contained within the package which is usually made out of stainless steel. Instrument gas and pilot preheating regulators are only used for freeze protection, and to heat up the gas before it reaches the pilot.

Auto reignition lowers the risk of gas leaks: if a flame goes out during operation, for example, from vibration or a gust of wind; due to misoperation—a user might not understand the "light" position must be maintained for about 0.5 to 2 seconds before turning the burner knob on fully.
