Some stoves must be lit manually with matches.
A gas ring is a burner designed to control the flow of gas to create stable, easily adjusted heat. Gas rings come in a variety of shapes, sizes and styles designed for everything from outdoor cooking to gas stoves. They are usually available at hardware stores, along with the necessary accessories to ensure they are safe to use.
When gas is used as a fuel for cooking, it is vital to be able to control the gas. A gas ring has a series of small nozzles that release gas when a valve is turned, allowing the gas to mix with oxygen so that complete combustion can take place. Depending on how wide the valve opens, the heat generated can be adjusted, allowing cooks to control the height and heat of the flames. When the valve is turned off, no gas can flow through the gas ring and it becomes inert again.
Gas rings control the flow of heat, usually to a stove.
On a gas stove, the burners are classically lit with a pilot light or an electric starter. In the case of a stove with pilot light, a small gas stove is kept lit constantly, so that when you light the burner, the gas ignites. On an electric start stove, turning the valve to send the gas to a gas ring also triggers an electrical signal that generates a spark, igniting the gas. Electric stoves can also be lit manually with the aid of a lighter or match.
Gas rings can also be placed directly over gas tanks, a technique that is sometimes used for outdoor cooking. These rings have the advantage of being potentially very large, which can be useful for cooking huge pots of food. They can also be designed to emit heat to heat an area, or to be decorative, in which case the gas ring can be partially closed for safety.
Cooking with a gas ring of any size is usually quite easy, but there are a few safety precautions to keep in mind. Gas rings should be cleaned regularly to remove buildup, ensuring all nozzles are clean, and it’s a good idea to check seals and connections between a gas ring and a gas source for leaks. Even a small leak can be potentially explosive, as well as harmful to pets and people who can inhale the gas.
If a gas ring is turned on and does not light immediately, it must be turned off again while the pilot and other connections are checked. Otherwise, the gas may ignite explosively when exposed to a flame.
