A fire broke out in a large building within the Taiyuan Iron and Steel Group Company on Hengshan Road, Jiancaoping District, Taiyuan City, Shanxi Province. It is understood that the building on fire stored a large amount of gas. It is already summer. So there is a certain probability that an explosion will occur. The population density near the factory should be relatively high, so the local police, fire and medical teams have been dispatched to the scene. At present, the accident scene has been completely controlled, there are no reports of injuries, and the cause of the accident is still under investigation.
Coal gas is only one energy gas and is one of the most commonly used energy sources in cities and industries. Coal gas is produced by gasification of coal. Gas is mainly divided into three types: water gas, semi-water gas and air gas. The main components of water gas are carbon monoxide and hydrogen. After combustion, carbon dioxide and water will be produced. If burned in the absence of oxygen, carbon monoxide and water will be produced, so for safety reasons , people will add some unpleasant smelling gases to the gas to prevent gas leakage accidents. Water gas is generally used by civilians. The main components of semi-water gas are nitrogen, hydrogen, carbon monoxide, etc. It is mainly used in industry, and the content of hydrogen and carbon monoxide is relatively low.
Coal gas is a flammable gas. When the gas encounters an open flame or sparks, it will burn violently. The gas will release a large amount of heat during the combustion process, and the large amount of heat will cause surrounding Air expands rapidly, and if hot air continues to expand in a closed environment, an explosion will occur. Gas explosion accidents were not uncommon in the past. Most of the reasons were because people were not very vigilant about the safe use of gas, the quality of gas equipment was not up to standard, and there were no good protection measures around the gas equipment. led to the accident. However, with the development of human society, coal production began to gradually decrease, and the state began to control coal mining. Now many residential areas have begun to use relatively safe natural gas.
