Is coal edible, and is coal edible?

Coal is not to be eaten. Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus and other elements, the sum of carbon, hydrogen and oxygen accounts for more than 95% of organic matter, which is a very important energy source, and is also an important raw material for metallurgy and chemical industry. The famous writer Zhu Ziqing also wrote a poem titled coal, giving it a unique symbolic meaning.

Uses of coal. The organic matter in the coal is gradually decomposed with the increase of temperature, and the volatile substances in the coal escape in the gaseous or vapor state to become coke oven gas and coal tar, while the non-volatile solid residue is coke. Coke oven gas is a fuel and an important chemical raw material.

Coal tar can be used to produce fertilizers, pesticides, synthetic fibers, synthetic rubber, paints, dyes, medicines, explosives, etc. Coke is mainly used in blast furnace ironmaking and casting, and can also be used to make nitrogen fertilizer and calcium carbide. Calcium carbide is a synthetic chemical product such as plastics, synthetic fibers, and synthetic rubber.

No, eating coal is the same as eating sand and soil, it will have an impact on the body, but it is not excluded that some strange people and strange things cannot be eaten by normal people.

It can be eaten, but it will affect the body and cause indigestion. Don't eat until you're in a hurry!

OK. It's just that it's going to be indigestion.

For humans, there is nothing that cannot be eaten.

I'm also here to find the answer, Mo Yan ** frog said that coal can be eaten, come and see!

If you really don't have anything to eat, you can only eat coal to stay alive.

Of course, it is not edible, coal is toxic, sulfur is a common harmful component in coal, and the content of other harmful elements in coal is generally not high, but it is extremely harmful, such as arsenic is a toxic element. In the combustion of coal, sulfur is the main source of environmental pollution in cities and towns.

Safety precautions for using coal:

All types of coal combustion will release carbon monoxide (colorless and odorless gas) during combustion, and it is necessary to pay attention to indoor ventilation during use, especially at night, and avoid sealing doors and windows. Be sure to ensure the height and diameter of the chimney, often check the flue gas pipeline and coal-fired stove, whether there is damage, whether it is smooth, whether the stove and the chimney connection is sealed, regularly clean the flue ash, the chimney outlet is best to install a wind shield to prevent wind, if there is a flue gas leakage, it should be stopped immediately to prevent carbon monoxide poisoning.

**Accident. Coal is the most abundant and widely distributed fossil fuel on the earth.

The main elements that make up the organic matter of coal are carbon, hydrogen, paramediate oxygen, nitrogen and sulfur, in addition, there are very small amounts of phosphorus, fluorine, chlorine and arsenic.

You can't eat it.

Coal is used in coking to produce coal tar and ammonia. Coke is an important raw material used in ironmaking. Coal tar can extract a variety of important compounds for industrial use. Coal can also be vaporized directly to produce water gas (a mixture of carbon monoxide and hydrogen), which can be used directly as a clean fuel.

Coal liquefaction is used to produce liquid synthetic fuels from coal: methane, and petrochemicals. Coal liquefaction is divided into two types: direct liquefaction and indirect liquefaction.

Direct liquefaction means carbonization and hydrogenation. Indirect liquefaction is to gasify coal first to produce water gas, and then synthesize fuels such as ethane and ethanol, and can also further synthesize fuel oil.

Coal can't be roasted and eaten. Ordinary coal will produce a large number of undesirable substances after combustion, and it is not allowed to be used, while the charcoal used in barbecue is generally charcoal or flammable carbon, which is specially treated. Barbecue food is generally contaminated with the smell of charcoal, so it is recommended to control the amount when eating, and do not use it too chaotically.

Coal can't be eaten in the mountains. Ordinary coal will produce a large number of undesirable substances after combustion, and it is not allowed to be used, while the charcoal used in barbecue is generally charcoal or flammable carbon, which is specially treated. Barbecue food will generally be contaminated with the smell of charcoal, so it is recommended to control the amount when eating and not overuse.

No. Coal contains highly polluting chemicals.

Highly polluting fuels mainly include coal (including coal products with coal as the main raw material), fuel oil (heavy oil and residual oil), charcoal, various combustible wastes and biocelery only fuels for direct combustion (trees, straw, sawdust, rice husks, bagasse, etc.), as well as light oil with sulfur content greater than ash content, artificial gas with sulfur content greater than 30mg m and ash content greater than 20mg m.

To sum up, if you use coal for barbecue, not only will you pollute the environment, but the food you grill will also be contaminated.

It's okay to eat.

It is true that some of it can be digested.

However, if you eat too much, you will hang.

It's more advanced than Kannon soil, but it's not as delicious as Guanyin soil.

Coal will produce a large amount of toxic substances such as sulfur dioxide and carbon dioxide when burned, and in the case of high temperatures, the food made will cause immeasurable harm to the human body, because coal and arsenic and other harmful substances, serious will damage the digestive and respiratory systems.

That's certainly not allowed. Good coal is also about the same as ordinary coal.

The composition of coal includes both organic and inorganic matter.

1. The main elements that constitute the organic matter of coal are carbon, hydrogen, oxygen, nitrogen and sulfur, in addition, there are very small amounts of phosphorus, fluorine, chlorine and arsenic and other elements. Carbon, hydrogen and oxygen are the main body of organic matter in coal, accounting for more than 95%.

2. The content of inorganic substances in coal is very small, mainly water and minerals, and their existence reduces the quality and utilization value of coal. Minerals are the main impurities of coal, such as sulfides, sulfates, carbonates, etc., most of which are harmful components.

The main components of coal are: carbon, hydrogen, oxygen, nitrogen, sulfur, ash, moisture, volatile matter (hydrocarbons, sulfides) miners eat coal in the collapsed mine, I have heard such a statement, it is also a helpless move, coal is not nutritious, and poisonous, do not eat it in the usual situation.

No, food refers to substances that can meet the body's normal physiological and biochemical energy needs and extend normal lifespan. For the human body, the substance that can meet the needs of normal life activities and help prolong life is called food. Food is usually made up of carbohydrates, fats, proteins, and water, which can provide nutrients for humans through eating or drinking.

1.plants, including cabbage, rice, cucumbers, etc.;

2.Animals, fish, chickens, ducks, pigs, etc.;

3.mushrooms, mushrooms, fungus, etc.;

Coal, on the other hand, is a combustible black or brownish-black sedimentary rock that usually occurs in rock formations or veins known as coal beds or coal seams. Because later exposed to increased temperatures and pressures, harder forms of coal can be considered metamorphic rocks, such as anthracite.

Coal is mainly made up of carbon, along with other elements in varying quantities, mainly hydrogen, sulphur, oxygen and nitrogen.

It is not to be eaten directly.
