What is the difference between natural gas and gas? Why do so many buildings use natural gas?

The gas of natural gas and coal gas is not the same, if you choose natural gas, then the purity will be relatively high, there are basically no impurities in the combustion process, and the pressure of transportation is relatively high, and the transmission speed is relatively fast. However, there are many impurities in the combustion process of gas, and many harmful substances will be emitted. So natural gas has a great advantage over it, so much so that many buildings are using natural gas.

What is the difference between natural gas and gas? Why do so many buildings use natural gas?

In the process of using natural gas and coal gas, the stoves used are also different. If you are using natural gas, then you must buy a natural gas stove, and if you are using gas, then you need to use a gas stove together, and the two stoves cannot be used with each other, nor can they be mixed, otherwise there will be serious consequences. Moreover, the pressure of natural gas is relatively small, and the pressure of gas is relatively large, so the stove needs to be transformed before it can be used.

It is also because the use of gas is more complicated, and the use of natural gas is relatively simple, so many buildings are using natural gas.

Natural gas and gasBurn valueIt's not the samePressure gaugeIt also varies

The pressure of natural gas is 2800 Pa, but the pressure of gas will be lower, if you want to change the gas stove to a natural gas stove, then you need to change its nozzle and fire, if the two are used together, then it will cause certain hidden dangers, and there will be a risk of fire.

Which is better natural gas or gas? I'll tell you by

If you choose **, relatively speaking, it is relatively less harmful to the human body, but there will also be gas poisoning.

phenomenon. In fact, there are pros and cons to both methods, so we can't make a fair judgment, but I also want to advise everyone that whether you use natural gas or coal gas, you need to pay attention to safety in the process of use. And in the process of use, we must pay attention to maintaining a ventilated state in time.

For natural gas and coal gas, they have different meanings, different essences, different principles, different compositions, **different, **different; The reason why many buildings are made of natural gas is that it is more convenient and relatively practical for natural 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 difference between gases: natural gas is generally dry gas, the composition is mainly methane, basically free of impurities, high calorific 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.

The difference between natural gas stove and gas stove: Usually the pressure of gas is large and the orifice diameter of the gas nozzle is small, while the pressure of natural gas is small and the aperture 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.

2. Combustion value and pressure: The working principle and shape of natural gas stove and gas stove are similar, the difference is that the orifice of the nozzle is different, we all know that the main reason is that the combustion calorific value of natural gas and gas is different, and their pressure is different. Everyone should choose according to the needs of their own family.

The pressure of natural gas is 2800 Pa, and the pressure of pipeline gas is 2000 Pa. An air call pipeline gas stove can be changed to a natural gas stove. This process requires changing the nozzle and fire lid of the stove.

The rest is handled by the gas company. The difference between a natural gas stove and a gas stove is not dangerous as long as it is changed, but it is very dangerous to burn natural gas if you use an air sensitive pipeline gas stove that has not been changed.

3. Combustion characteristics: In terms of combustion characteristics, natural gas and coal gas are not interchangeable, so when gas is converted to natural gas, the original gas cooker, appliances, meters, and transmission and distribution network must be replaced or transformed. Among them, artificial gas stoves should be transformed or updated to natural gas stoves, and household stoves should be transformed into natural gas stoves by replacing the nozzle and fire hole cover.

Household water heaters are converted into natural gas water heaters by replacing nozzle (main fire, permanent open flame, etc.) burners.
