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.

Safety

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.
