Anonymous users2024-01-24It could be a physical explosion or a chemical explosion.
A physical explosion does not involve a chemical change, but a sudden rupture of a pipeline caused by a large change in pressure caused by a change in temperature of a simple gas.
Chemical explosions are caused by a sudden increase in gas pressure caused by the intense heat release caused by combustion.

Anonymous users2024-01-23If it is simply a broken gas tank, it is a physical explosion. The phenomenon is that there is no flame, but only because of the sudden drop in pressure: due to various reasons such as impact and vibration, the surface of the gas storage container is cracked or the structure is changed and cannot withstand the original pressure, so that the liquid gas or compressed gas with a sudden decrease in pressure is rapidly vaporized or expanded, and passes through the cracks on the surface of the container at high speed, breaking through and destroying the original structure of the container; The high-pressure gas makes a loud explosion sound at the moment of decompression expansion, resulting in an explosion.
If gas or fuel is accidentally ignited, it is a chemical explosion. A chemical explosion is caused by the reaction of matter to instantly produce a large amount of heat, heating the surrounding air and the fuel itself that has been vaporized, so a large amount of rapidly expanding high-temperature gas quickly spreads to the surrounding area, producing an explosion shock wave.
If the user's kitchen comes into contact with an open flame and natural gas explosion, of course, it is a chemical explosion.

If there is an explosion, there are two main reasons: 1. Leakage. There is a gas leak, and the gas mixture is detonated during ignition; 2. Ignition failure. >>>More
First of all, hot weather pipelines generally do not explode, and natural gas can only explode when it is mixed with oxygen in large quantities to reach the explosion limit and encounter ignition energy. Secondly, kitchen renovation as a rental house is not in line with fire regulations, it is recommended not to rent and report the landlord, human life is a matter of heaven, do not underestimate.
You should find the natural gas management center in the community to see if there is a leak in the natural gas pipeline or a valve leak. Once the leak is identified, replace the valve or line. Because, even if you don't use natural gas for a short period of time, there is a possibility of gas leakage!
Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.). And people have been common for a long time"Natural gas"The definition is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas. >>>More
So what else can be done, electric water heaters, solar energy, heat exchangers (which can only be used for heating in winter), there is no other way.
