Autonomous gas supply of a country house is an independent, convenient and safe system for supplying a private country house or cottage with liquefied hydrocarbon gas, which has a number of advantages: uninterrupted gas supply, safety, efficiency and environmental friendliness.
Gas tanks for a country private house: prices in St. Petersburg
When choosing a gas tank for a cottage, you need to decide on its volume. An average of 25–30 liters of gas per year is spent on heating 1 m² of a house area. It must be remembered that the useful volume of the gas tank is 85% of the geometric volume, i.e. the maximum capacity of the gas tank with a volume of 4850 liters is 4122 liters.
Gas holders for a country house are divided into vertical and horizontal, as well as underground and ground. For a country house or cottage, underground horizontal tanks are used, which have the largest evaporation area, and, consequently, greater productivity compared to vertical ones (2–3 times).
Properly installed underground gas tanks work properly and smoothly in Russian conditions. The conditions for the use of gas tanks in the Moscow and Leningrad regions are characterized by severe freezing of the soil in the cold season and the presence of a high level of groundwater. That is why in autonomous gasification systemsinstalled by Gazovoz, tanks with high necks and high tubes are used. Such gasholders are installed below the level of soil freezing and provide uninterrupted gas supply even in the most severe frosts.
The Gazovoz company assembles gas tanks, which are manufactured at the Chemet plant, known since the times of the Soviet Union, and which is the largest European manufacturer of pressure vessels. Chemet tanks are of high quality, modern design and high safety level.
Autonomous gas supply: what is it?
as a fuel in autonomous gasification systems liquefied hydrocarbon gas (LHG) is used, which is stored in a special underground tank — a gas holder.
According to regulatory documents, an underground tank must be installed at a distance of at least 10 meters from the house and other residential buildings.
Autonomous gasification system works on the principle of natural gas evaporation. Inside the gas tank, the propane-butane mixture passes into a gaseous state, then its pressure is reduced by a regulator to 30–50 mbar, and the gas enters the boiler room or kitchen through an underground gas pipeline from HDPE pipes (low pressure polyethylene).
To prevent the gas tank from floating under the action of high groundwater, the tank is installed on a concrete slab and attached to it with stainless steel anchors. In order to protect against electrochemical corrosion, the system includes an anode-cathode protection, which, by means of magnesium oxidation, preserves and restores the iron of the gas tank walls. This protection extends the life of the tank and the entire system. autonomous gas supply generally.
If autonomous gasification of a large object (area over 1000 m²) is carried out, it is necessary to additionally install LPG evaporators, which provide a high rate of transition of liquefied petroleum gas from the liquid phase to the vapor phase.
Organization and operation of the autonomous gasification system
Organization and creation autonomous gasification not as expensive as it seems at first glance. The highest costs are at the construction stage. However, due to low maintenance costs, an autonomous gas supply system is more economical than heating with diesel fuel or electricity.
Autonomous gasification of a private house includes automation that blocks the gas supply in the event of a leak or fire. In addition, the gas tank and pressure regulator have safety devices.
Autonomous gasification of a country houseperformed by qualified professionals is much safer than using conventional gas cylinders.
Refueling gas tanks
The gas tank of the autonomous gasification system of a private house is refueled no more than 2–3 times a year by special vehicles — gas carriers, and the refueling itself is carried out by professional and certified specialists.
