What is the difference between natural gas and gas? Under normal circumstances, which one is better?

Natural gas is much better than coal gas, because gas is more polluting than natural gas in the process of production and use, and with the large-scale application of natural gas, coal gas is becoming less and less, and natural gas produces much more heat than coal gas.

Natural gas, as the name suggests, is a class of natural gases naturally produced in nature, mainly hydrocarbon and non-hydrocarbon mixed gases, often produced in oil fields, so the general oil field not only produces oil, but also produces natural gas, natural gas is also due to the ancient organisms are buried underground, in the high temperature and high pressure environment and the decomposition of microorganisms will decompose organic organisms into small molecule hydrocarbon substances. Therefore, natural gas mostly exists with oil, and organic hydrocarbons with large molecular weight mainly exist in liquid form, which is what we call **. Whereas small molecules such as methane, ethane, and propane are found in gaseous form in the upper part of the oil, and these natural gases are sequestered underground due to the sealing of the rock layers.

As you can guess from the name, there is a certain relationship between coal and coal, and it is true that the main raw material for gas production is coal. There are many ways to produce coal gas, the basic principle is to use coal and water or air to react under certain conditions to produce carbon monoxide and hydrogen, we can think of coal gas as a type of gas produced by incomplete combustion of coal.

Due to the higher danger of coal gas, natural gas has now become the mainstream of household fuels, but these gaseous fuels can not be negligent in the process of use, one of the common hidden dangers is that they are prone to occur after leakage**. Therefore, although natural gas is cleaner and safer than coal gas, it should not be used carelessly.

Natural gas generally needs to be piped throughout the community, and it is not possible to install it for every household in remote areas. Coal gas is generally liquefied petroleum, and its composition is different from that of natural gas, which can be stored through gas tanks, which is more convenient than natural gas, but there may be gas leaks, so natural gas is safer. In general, it is more appropriate to use gas.

The composition of natural gas is relatively clean, free of impurities, and the pressure is relatively less, while the composition of natural gas is more complex and has more impurities, so I personally think that it will be better to use natural gas.

Household (based on electric yuan): when the bottled gas is less than 89 yuan, using gas is cheaper than electricity; Rent a house (based on electricity yuan): save electricity when the gas cylinder is less than 222 yuan!

Because bottled gas is basically impossible to be greater than this price, the city still uses natural gas and gas tanks for cooking, and now a lot of natural gas is imported from the west and east, and some of it is gasified from coal.

<> 1 kilogram of gas is equivalent to about 11 kilowatt-hours of electricity, a bottle of gas = 15 kilograms, and the use of a bottle of gas is equivalent to the use of electricity: 11 15 = 165 kilowatt-hours. If you use electricity, you can use an induction cooker or kettle, 1500W of electricity per hour, which is equivalent to 25W per minute, and the capacity of gas per minute can reach 75W.

It must be more cost-effective to use gas, but it depends on the price of your electricity there. In general, it is more cost-effective to use gas in households. But gas and electricity are necessary for the family, and our family now uses gas for water heaters.

Gas is more convenient, there are household gas tank type, bottled type Cass furnace, but the cost is higher. Electricity generally has rice cookers, induction cookers and other equipment, as long as there is electricity can be used, the cost of use is higher than natural gas but lower than coal gas. Personally, I think it is cost-effective to use gas, a bottle of gas is 120 yuan, a family of four can use it for two months, and the meals made are more fragrant and delicious than electricity.

If you use electricity, 120 yuan is not enough for a month, and there is no fragrance when cooking. As the saying goes, people take food as their day, and eating is a very important thing in life. With the progress of society, people have brought great convenience to life from the past to use firewood for cooking, then canned gas, then gas pipes, and now induction cookers.

I feel the same, mainly depending on how many appliances there are at home. We now use electricity for cooking and bathing, and the monthly electricity bill is similar to the cost of cooking and bathing with natural gas in the past.

Coal gas is perfect, and natural gas is better than blue. This should be the difference. For our daily use, natural gas is less than gas because the quality of natural gas is relatively light, and it spreads upwards after leakage.

Personally, I think that if conditions permit, try to use natural gas as much as possible.

Natural gas is a colorless and odorless gas with relatively high safety, and coal gas is extracted from oil, which is prone to leakage in a sealed environment, which can cause danger. Natural gas is usually more economical than coal gas.

Natural gas is more affordable. Different gases: Natural gas is relatively pure and basically free of any impurities. There are more impurities in coal gas, not only moisture, but also dust, hydrogen sulfide, etc.

Natural gas is a colorless and odorless gas, the main component is methane, there is no corrosiveness and mutuality, no need to refine can be used, in order to ensure safety, odorous gas is added to it, it is easier to be found when a leak occurs. Since it is lighter than air, it will float in the air after leaking, and it is easier to diffuse than gas, so it is safer.

Coal gas is usually a by-product obtained after oil exploitation and processing, and the main components are propane, butane, etc., which leak in a sealed environment, and people will feel difficult to breathe and dizzy after reaching a certain amount.

1 kilogram of liquefied petroleum gas ** is about yuan, and a kilogram of liquefied petroleum gas is yuan. The ** of 1 cubic meter of natural gas is about 3 yuan (less than 3 yuan in most cities). There is no doubt that natural gas is much more cost-effective than liquefied petroleum gas.

Of course natural gas.

The first is safety, at least the natural gas is non-toxic.

The second is that the calorific value is large, and the calorific value of pure natural gas is greater than that of coal gas.

In some places, piped gas was originally used, but after switching to piped natural gas, some nitrogen was mixed with natural gas in order to balance the calorific value. Otherwise, the calorific value of pure gas is too large, and the original gas stove, water heater or something will have to be replaced with a new one.

The differences between natural gas and coal gas are as follows:

1. Different gases: The purity of natural gas is relatively high, and the main components are methane and hydrogen, and there is no special smell. The combustion is relatively sufficient, there are no impurities, the main component of coal gas is carbon monoxide, and there are more impurities, dust, colorless and odorless but toxic.

2. The use of stoves is different: the use of natural gas requires natural gas stoves, and the use of gas requires gas stoves, both of which have their own special appliances and cannot be mixed.

Causes of the formation of natural gas

The causes of natural gas are varied, the formation of natural gas runs through the whole process of diagenesis, plutonic formation, post-formation until metamorphism, various types of organic matter can form natural gas, saprolite-type organic matter is both oil and gas, humic organic matter mainly produces gaseous hydrocarbons.

Biogenesis. In the early stage of diagenesis, in the shallow biochemical zone, the natural gas formed by the fermentation and synthesis of sedimentary organic matter by microorganisms is called biogenetic gas. It is sometimes mixed with gases formed by early low-temperature degradation. Biogenetic gas occurs in rock formations with shallow burial, new age and low degree of evolution, and is dominated by methane-containing gas.

The prerequisite for the formation of biogenic gas is more abundant organic matter and a strong reducing environment.

Natural gas and coal gas are clean, easy to regulate, and have high thermal efficiency. The main differences are: different compositions, different concentration ranges of combustion, different harmfulness, different calorific values, different pressures, and natural gas is much cheaper than coal gas.

Coal gas is a mixture of various gases, containing water, oil and dust, ammonia, hydrogen sulfide and other impurities, and the delivery pressure is low. Natural gas is generally dry gas, mainly composed of methane, basically free of impurities, high calorific value, slow flame propagation speed, and high transmission pressure.

"First of all, the composition of the two is different, natural gas is mainly composed of methane, less impurities and high purity, while coal gas is a mixture of carbon monoxide, methane and other gases, with low purity. Secondly, the pressure is also different, the former is close to 3000pa, and the latter is about 2000pa, which means that the diameter of the gas nozzle used in the two is also very different and cannot be mixed. Finally, natural gas burns more thoroughly and safely, while gas is a secondary energy source that produces harmful gases when burned. ”

1. The gas composition is different

Natural gas is generally dry gas, the composition is mainly methane, basically free of impurities, jujube has high heat value, slow flame propagation speed, and high transmission pressure. Coal gas is a mixture of various gases, containing impurities such as moisture, oil and dust, ammonia, hydrogen sulfide, etc., and the delivery pressure is low.

2. The pressure is different

The pressure of natural gas is 2800 Pa, and the pressure of pipeline gas is 2000 Pa.

3. **Different

Coal gas is called gas because it is made from coal. Natural gas, on the other hand, is extracted from oil and gas fields, that is, from the ground.

4. **Different

The ** of coal gas and natural gas is not fixed, mainly depends on the market value of the local area, the ** of each region is not the same, for the area with rich natural gas resources, the ** of natural gas is lower, and for the natural gas transported outside the state, the natural gas ** in that area will be more expensive.

5. The use of stoves is different

Usually, the pressure of gas is high and the orifice size of the gas nozzle is small, while the pressure of natural gas is small and the orifice size is large, so they cannot be mixed. In addition, when designing the stove, it is usually also concerned about the oxygen (combustion capacity, i.e. mixing ratio, LPG requires more air, and the other two are less.

Summary. The difference between natural gas and coal gas is: 1. The main component of natural gas is methane, which has a relatively high purity, while coal gas is a mixture of various gases, including moisture, hydrogen sulfide and other impurities.

2. Carbon monoxide will only exist when natural gas is not burned out, which is generally non-toxic and harmless. When the gas is burned, a large amount of oxygen is produced, and carbon dioxide is easily produced afterwards, and in a sealed environment, it is easy to be poisoned. The above information is on the web.
