Gas stove
A gas stove is a stove that is fuelled by combustible gas such as syngas, natural gas, propane, butane, liquefied petroleum gas or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836. This new cooking technology had the advantage of being easily adjustable and could be turned off when not in use. The gas stove, however, did not become a commercial success until the 1880s, by which time supplies of piped gas were available in cities and large towns in Britain. The stoves became widespread on the European Continent and in the United States in the early 20th century.
Gas stoves became more common when the oven was integrated into the base and the size was reduced to better fit in with the rest of the kitchen furniture. By the 1910s, producers started to enamel their gas stoves for easier cleaning. Ignition of the gas was originally by match and this was followed by the more convenient pilot light. This had the disadvantage of continually consuming gas. The oven still needed to be lit by match and accidentally turning on the gas without igniting it could lead to an explosion. To prevent these types of accidents, oven manufacturers developed and installed a safety valve called a flame failure device for gas hobs (cooktops) and ovens. Most modern gas stoves have electronic ignition, automatic timers for the oven and extractor hoods to remove fumes.
Gas stoves are an indoor common fossil-fuel appliance that contribute significant levels of indoor air pollution, which is why they require good ventilation to maintain acceptable air quality. They also expose users to pollutants, such as nitrogen dioxide, which can trigger respiratory diseases, and have shown an increase in the rates of asthma in children. Gas stoves also release methane. Research in 2022 estimated that the methane emissions from gas stoves in the United States were equivalent to the greenhouse gas emissions of 500,000 cars. About 80% of methane emissions were found to occur even when stoves are turned off, as the result of tiny leaks in gas lines and fittings. Although methane contains less carbon than other fuels, gas venting and unintended fugitive emissions throughout the supply chain results in natural gas having a similar carbon footprint to other fossil fuels overall. In June 2023, Stanford researchers found combustion from gas stoves can raise indoor levels of benzene, a potent carcinogen linked to a higher risk of blood cell cancers, to more than that found in secondhand tobacco smoke.
