What gas in the apartment - natural or liquefied?

What kind of gas is used in apartments - natural or liquefied? In the kitchen stoves and systems for heating the premises, fossil fuels are supplied, which is extracted from the bowels of the earth. Naturally, before entering the pipes that lead to our houses, the gas is pre-processed, substances added to it that make it possible to make its composition optimal for household use. Let's find out what kind of gas is in the apartment?

Composition

What kind of gas in the apartments is propane or methane? In fact, the fuel that is supplied to homes is a mixture not only of these substances, but also a whole mass of additional substances. In fact, its basis is methane. The content of this substance in natural fuel can be from 70 to 98%.

And answering the question, what kind of gas in the apartment, we can say that in addition to methane in its composition includes the following substances:

• propane;
• butane;
• Hydrogen sulphide;
• carbon dioxide;
• A pair of water.

To protect such fuel and make it more quality, optimal for domestic use, suppliers are subject to natural fossil cleaning, remove excess impurities from it and then sell it to consumers.

What is the gas pressure in the apartment?

Before natural fossil fuels burn on kitchen stoves in our homes, it overcomes tens and hundreds of thousands of kilometers along main gas pipelines. The pressure in such gas transport arteries is extremely high and can reach an indicator of the order of 11.8 MPa.

Obviously, this pressure indicator does not meet the safety requirements for domestic consumption. Therefore, fuel is pre-fed to gas distribution stations. Here, its pressure is reduced to 1.2 MPa. In addition, fuel stations are cleaned at such stations.

Why does the gas in the apartments smell?

What kind of gas enters the apartment? Everyone knows from the school curriculum that natural fuel has no color and smell. A characteristic aroma is given to him at all the same gas distribution stations. To such fuel add so-called odorants - specific substances which are recognized by human smell and, accordingly, help prevent a life-threatening gas leak in the room. They have a rather unpleasant smell. The latter reminds us of the spirit that comes from decaying cabbage or sordid hay.

Often used for this purpose, odorants are substances such as ethanethiol and ethyl mercaptan. These substances are presented in the form of odorous liquids. When processing natural gas, they are sprayed into its structure, which allows to give the fuel a characteristic aroma.

Is natural gas toxic

So we found out what kind of gas is being supplied to the apartments. Now let's see if such fuel can harm health.

Contrary to common misconceptions, the gas that is supplied to our homes is absolutely non-toxic. Therefore, poisoning with its inhalation is extremely difficult. However, there are exceptions everywhere. Numerous cases are known when consumers died in gassed premises. However, the lethal outcome in such situations did not come from intoxication, but from suffocation. The fact is that molecules of carbon dioxide, a small percentage of which is present in the composition of natural fuels, are able to displace oxygen molecules from space. Thus, breathing becomes difficult, and when the room is filled with gas completely impossible.

Explosion hazard of natural gas

Which gas in the apartment is explosive or not? The concentration of the fuel for the occurrence of the effect of its ignition is extremely thin. The probability of an explosion depends on the gas composition, the pressure level, and the ambient temperature.

A dangerous situation can occur only if the concentration of natural fuel in the room reaches 15% relative to the total air mass.

It is impossible to independently determine the percentage of gas in space without the use of specialized measuring equipment. Therefore, having sensed a characteristic aroma, it is necessary to cut off the supply of fuel to household appliances. It is also extremely important to de-energize devices that use electrical impulses. This concerns not only home appliances, but also devices that function from batteries, batteries. As practice shows, when the gas concentration in the room is at 15% of the total amount of air, its ignition can occur even from the work of a mobile phone or laptop.

When there is a smell of gas, you must immediately open all doors and windows in the room. Airing habitation will reduce the likelihood of an explosion prior to the arrival of the emergency service.

How to protect yourself while operating gas appliances

To ensure that natural fuel only benefits, it is necessary to follow the generally established rules for the use of gas appliances:

1. It is recommended that specialists be called annually to check the traction in the premises.
2. Do not completely isolate the ventilation grilles, as well as windows and doors in winter.
3. Before leaving home for a long time, it is necessary to cover all gas valves and valves, as well as to disconnect electrical devices.
4. Do not leave functioning gas appliances unattended.
5. Having felt the smell of gas, you should avoid turning on the light and using an open flame.

As evidenced by this or that color of fire in the burner

The shade of the flame in the gas burner can tell you about the peculiarities of burning natural fuels. If the fire has a saturated blue color of a homogeneous structure, then the gas is completely burned. In this case, the maximum amount of heat is released into the space.

And what happens in cases when the flame in the burner gets a reddish or bright yellow hue? If the gas during combustion has any other color than blue, this may indicate that a limited amount of air is supplied to the burner or the gas is of poor quality. In this case, fossil fuel does not efficiently heat up. To eliminate this drawback, it is enough to call a qualified specialist by contacting the gas sector.

As can be seen, the color of the gas during combustion can provide useful information. A yellowish or reddish shade of fuel upon ignition suggests that a low-density gas is fed into the house. And since heating boilers are designed for fuel consumption of a certain quality, if the gas density decreases, the equipment will need more substance to create a comfortable temperature.

In fact, the yellow or red tongues of fire on the igniter indicate that more fuel will be consumed by the instruments. Culprits of such omission may be the management companies. Some of them intentionally reduce the content of carbon dioxide and hydrocarbon in the gas. Therefore, when changing the color of the flame on the gas burner, users have the right to contact the supplier for clarification.

Finally

So we figured out what kind of gas in the apartment, and answered a whole series of other questions. Finally, it should be noted that the use of high-quality natural fuel is an extremely important point, which affects the stable operation and efficiency of the equipment. Unfortunately, consumers do not have the opportunity to independently determine how high-quality fuel is fed into the house. Therefore it is important to periodically recruit specialists to check gas equipment.
