China The Western Han Dynasty is the earliest period of mining and using coal in China, the color of coal is dark, like a stone, so in ancient times there are stone Nirvana, carbon, graphite, Wujin, Shiheidan and other names written in the late Spring and Autumn Period and the beginning of the Warring States Period (about the fifth century B.C.), the Classic of Mountains and Seas, the Five Tibetan Mountain Sutra said, the mountain of the female bed, the mountain of the female bed, the mountain of the female bed is in present-day Shaanxi, and the mountain of the female bed is in present-day Sichuan, indicating that coal has been found in these areas at that time, which is the earliest record of coal in China.
China is the first country in the world to mine and use coal. In Europe, there was a written record of coal in 315 AD, about 800 years later than the written record in China; Coal mining in England only began in the 13th century, about 1400 years later than China.
The name "oil" was first seen more than 900 years ago in the Northern Song Dynasty scientist Shen Kuo (1031?1095). The book says:
There is oil in Luyan, and it is said that the fat water in Gaonu County is also ......This thing will be great in the world, and it will be done from the beginning, and it will be covered with oil at most, and it will be born in the earth endlessly. ”
About 2,000 years ago, people in northwest China knew that the oil floating on the surface of the water was "extremely bright", so they collected it into containers and used it to light lamps. Northern Wei Dynasty Li Daoyuan (466 472?In 527), there was a record of oil "anointing carts and water scoop nails" (Note:
The hub of the iron is also, that is, the axle. This sentence means: with ** painted on the bearings of the car and the water mill, very good).
Since the Tang and Song dynasties, oil has been used to make "stone candles" and ink. During the Northern Song Dynasty, there was a workshop for refining "fierce fire oil" in Kaifeng, the capital city, and the fierce fire oil produced was mainly used for military purposes.
The earliest oil wells also appeared in the Song Dynasty. According to the records of the early Yuan Dynasty's "Yuan Yi Tongzhi", "there is a well of oil drilled in the south of Yinghe in Yanchang County, and its oil is combustible, and it also treats six animal scabies." from).

Coal, oil, and natural gas are collectively referred toFossil fuels
Coal, oil, and natural gas are fossil fuels, and they are non-renewable and non-renewable energy.
Minerals such as coal, oil, and natural gas are produced in 10,000 years at the shortest. From the deposition, compaction, burial, and then through a series of evolutionary processes of organic matter, this time can be as short as tens of thousands of years, and as long as tens of millions or even hundreds of millions of years.
Precautions for using gas burners
Use gas burning appliances that meet the requirements of the gas source and have flame-out protection devices, and gas burning appliances should be installed in well-ventilated kitchens, and should not be installed in bedrooms, bathrooms, living rooms, and basements.
Hoods and exhaust fans should be installed in rooms where gas burning appliances are used.
and other exhaust facilities, gas water heaters.
Gas heating stoves need to be installed with special flues, and it is strictly forbidden to use in-line gas water heaters indoors.
The installation of gas burning appliances (except household gas stoves) should be installed by qualified units, and the relevant procedures should be handled by the gas ** enterprise before installation, and the installation can only be carried out after meeting the conditions.

Among fossil fuels, natural gas is the most likely to replace coal in the energy mix in the future.
Data Extension:
Natural gas refers to all gases that exist naturally in the natural realm, 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.).
The long-term common definition of "natural gas" 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. The composition of the hosiery base is mainly hydrocarbons and contains non-hydrocarbon gases.
On May 6, 2020, PetroChina's Southwest Oil and Gas Field Gongna Vertical Division disclosed that the company had discovered a new zone rich in natural gas, with an estimated potential resource of more than one trillion cubic meters.
On February 28, 2023, the National Bureau of Statistics released the Statistical Communiqué of the People's Republic of China on National Economic and Social Development in 2022, which preliminarily calculates that natural gas consumption will decline, and the consumption of clean energy such as natural gas, hydropower, nuclear power, wind power, and solar power generation will account for an increase of one percentage point in total energy consumption.
Natural gas is contained in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcanic gas and biogenerated gas, and a small amount also comes from coal seams. It is a high-quality fuel and chemical feedstock.

The energy used in China is dominated by coal. Coal is China's largest energy source, accounting for more than 70% of the country's total energy production and consumption China is the country with the largest coal production in the world.
In the "Energy Development Strategic Action Plan (2014-2020)" issued in 2014, it was determined that the focus will be on the construction of northern Shanxi, central Jinzhong, eastern Jindong, Shendong and northern Shaanxi.
Huanglong, Ningdong, Luxi, Lianghuai, Yungui, Jizhong.
14 large-scale coal bases of 100 million tons in Henan, eastern Inner Mongolia and Xinjiang. Data show that in 2013, 14 large-scale coal bases produced 100 million tons, accounting for 91% of the country's total output.

Coal, oil, and natural gas are known as fossil fuels.
Coal, oil, and natural gas are non-renewable. Coal, oil, and natural gas are known as the three major fossil fuels, coal is called "the food of industry", oil is called "the blood of industry", coal and oil are not only important fuels, but also important chemical raw materials The main component of natural gas is methane, which is a compound containing carbon elements and belongs to organic matter. As an energy source, forward energy can be gradually replaced by wind energy, solar energy, tidal energy, nuclear energy, geothermal energy, and biomass energy in the field of power generation.
Coal, oil and gas are formed by the accumulation of paleontological remains through geological time changes, and this kind of energy is non-renewable after use, and is collectively referred to as non-renewable energy. Non-renewable energy refers to the energy that has been formed in nature for hundreds of millions of years, cannot be restored in the short term, and with large-scale development and utilization, the reserves are getting smaller and smaller, and there is always a day of depletion.
Definition of fossil energy
Fossil energy refers to carbon-containing energy represented by oil, natural gas, and coal, which can actually be regarded as a chemical energy, and its energy utilization is mainly based on the chemical exothermic reaction of carbon oxidation to CO2 (including hydroxide to water). Many of the reactions involved in carbon are the basic chemical reactions existing in nature, which are related to the whole process of the origin of life, the annihilation of life organisms, the development of the bridge to the extinction and collapse of bridges, and the whole process of the formation, utilization and consumption of fossil energy.
Fossil fuels include natural resources such as coal, oil, and natural gas. They are deposited from fossils of ancient organisms and are a primary energy source. Fossil fuels emit toxic gases when they are not completely burned, but they are essential fuels for human beings.
The above content refers to Encyclopedia - Fossil Energy.

Fossil fuels. Coal, oil, and natural gas are all formed by the accumulation of paleontological remains through geological time changes, so they are called fossil energy. The shortest generation of minerals such as coal, hail, coal, oil, and natural gas is also calculated in 10,000 years.
From the deposition, compaction, burial, and then through a series of evolutionary processes of organic matter, this time can be as short as tens of thousands of years, and as long as tens of millions or even hundreds of millions of years.

Coal, oil, and natural gas are collectively referred to as fossil fuel resources.
Fossil fuels, also known as mineral-derived fossil fuels, are hydrocarbons or mixtures of hydrocarbon derivatives that include natural resources such as coal, oil, and natural gas. Fossil fuels are non-renewable resources formed by the remains of ancient organisms through a complex series of changes.
The use of fossil fuels can enable large-scale industrial development and replace water wheels. When electricity is generated, energy is generated during the burning of fossil fuels, which propels turbines to generate power.
Old-style generators used steam to propel turbines. Many power stations now use gas turbine engines, which use gas to propel turbines directly.
The crisis caused by the overuse of fossil fuels:
Fossil fuels are non-renewable fuels and are stored in finite quantities in the earth's crust. It will run out soon. Fossil fuels contain sulphur, which produces toxic sulphur dioxide when burned, and also causes acid rain and damages the ecological balance. Burning fossil fuels also produces carbon particles, which pollute the air and cause respiratory diseases.
Burning fossil fuels releases carbon dioxide, the most greenhouse gas caused by human activity. Scientists have calculated how safe the atmosphere is to absorb carbon dioxide to avoid climate change, and if emissions exceed the safe threshold, the climate will shift dramatically, making it impossible for ecosystems to adapt, and the planet will be headed for an irreversible and uncontrollable situation.
Oil and natural gas are formed by organisms in the earth's crust, and the corpses of these organisms go through various reactions to produce some oil, which forms natural gas or oil.
The organic matter in coal is a complex polymer organic compound, which is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and the sum of carbon, hydrogen and oxygen accounts for more than 95% of the organic matter. The inorganic matter in coal also contains small amounts of carbon, hydrogen, oxygen, sulfur and other elements.

The source of the Iranian crisis is that the United States said that Iran is developing nuclear **, and the United States said that if Iran does not stop the research and development of nuclear **, it will impose sanctions on Iran and ban the export of Iranian oil. The economic interests of the United States will suffer a great loss, and the United States will not do it, so the two will do it. Iran says that it has the strength to blockade the Strait of Hormuz, and you can see it if you look at the map, the Strait of Hormuz is close to Iran, and it is very narrow, which is equivalent to the throat of the Persian Gulf. >>>More
Salt is not only an indispensable condiment in people's daily life, but also one of the important substances to maintain the normal metabolism of the human body. As for the use of salt, people are generally limited to the understanding of the seasoning of table salt, and the understanding of its other uses is not enough, so I have conducted research on various uses of salt by means of interviews and research and data review. >>>More
