A gas generator from main gas is the most common power source. Of course, there are devices that operate on another type of fuel. But they have a number of disadvantages.
The gas generator on the main gas practically does not emit noise in operation, and also does not emit harmful substances into the environment. Such a device is easy to install and use.
Advantages
Among the positive aspects of gas generators it is worth highlighting:
- The operation of the device for a long time. The generator works until the fuel runs out in the main pipeline. In order to be able to work more, install an additional balloon system. This indicator is the main, in comparison with other type of equipment.
- Low cost of a cubic meter of gas, in comparison with other types of fuel. In addition, fuel can be in tanks for unlimited time, in contrast to alternative sources.
- Long service life. Details, namely structural elements, practically do not wear out. As a result, a small amount of combustion products leaves the apparatus. Therefore, the occurrence of corrosion is minimized.
- Environmental friendliness. During its work no harmful substances are emitted.
disadvantages
Like all devices, the gas generator on the main gas has disadvantages:
- Increased fuel explosion hazard. Various explosions and fires appear more than when using other devices. Therefore, it is necessary to provide additional transportation conditions.
- Collection of documentation. To use the gas generator on the main gas, you must obtain permission, and also develop a project. Its cost will be much higher than the device itself.
- In the room where the generator will be located, provide exhaust ventilation.
- When freezing temperatures occur, the fuel cylinder must be moved to a warmer room.
Types of devices
In residential premises, you can use two types of generators. It is reserve and permanent.
The first type gas generator can work up to 20 hours. The unit is cooled by air. It can function even more properly. But at the same time, its motor resource will be reduced. The generator can only operate when it is in a refrigerated state. Therefore, most people use it when turning off the electricity.
If you need to use a gas element for a long time, you should choose the second type of such a device. Its main feature is liquid cooling. Such equipment is able to turn on and off independently. Therefore, it manages to cool in these periods of time. When this happens, the inverters, along with the batteries, supply electricity to other devices. Devices of this type can be used at high power, as well as in the event of a breakdown, are quickly repaired.
Gas generators for a home on gas
When using this equipment, two types of gas are used. It is liquefied and main. In the first case, fuel is consumed from cylinders, and in the second, from the main pipeline. There are devices that can operate on another type of fuel, such as methane.
It is recommended to use liquefied fuel generators if a heating boiler is installed in the house.
With a generator power of 6 kW, a cylinder with a capacity of 50 liters is enough to work for 20 hours.
The main gas pipeline, which is brought to the house, is a profitable power source. Before installing it, you need to find out the pressure in the pipeline. With a low value, such a gas generator for the home will not function at high power. Before you connect it, you must obtain permission from the appropriate company.
Gas generator selection
To choose the right item for your living space, consider the following: Fuel consumption, power, voltage, etc. So, we will consider what capacities of this equipment are found:
- 5-6 kW - such a device is suitable for a small residential building to conduct electricity in it, as well as for cooking;
- 15-20 kW - the equipment can function for 12 hours, which makes it possible to obtain the necessary comfort in the room by connecting different types of electrical appliances. Such a long-term supply is possible due to air cooling;
- 10-25 kW - this equipment works for a long time using liquid cooling; most of these devices are used in country houses or cottages;
- over 25 kW - I use such powerful devices for production purposes in small enterprises.
As for such an indicator as voltage, single-phase and three-phase gas devices are distinguished here. The first type is used to supply electric current to any household appliances with a voltage of 220 V. The second type, most often, is used in country houses or cottages for mixed power supply with a voltage of 220-380 V.
If three consumers are not connected to the device when using the three-phase type, then a single-phase automation system can be used.
The same can be done with a single-phase view, that is, install three-phase automation and use the device for three consumers.
When choosing a gas generator, you should pay attention to the electric start and the automatic system. These functions are responsible for automatically turning on and off the equipment. In addition, the gas generator from the main gas with auto start has an oil sensor that protects it from breakdowns.
Mounting
As a rule, such devices are equipped with a special protective cover. To make the installation of equipment, such conditions are necessary:
- the temperature in the room should be above 0 ° C, if this condition is not met, then it is necessary to insulate;
- ventilation must be provided in the room;
- you need to take care of the removal of combustion products.
Today, there are such models that can be installed on the street. For this they are equipped with a special casing. Their advantage is that they will not take up space in the room. In addition, they will function on the street even at low temperatures and rainfall. It can work at -30 ° C. The cost of such equipment reaches 200,000 rubles. This price is much higher than that of diesel-based analogues with the same characteristics. But such a system quickly pays off if there is a gas boiler in the house for heating.
Arrangement of premises
Typically, these devices are installed in a basement, boiler room or other convenient room. The element can work only under the influence of positive temperatures. The place must comply with all technical requirements for boiler rooms:
- the volume of the room should be more than 15 m3;
- ventilation must be provided;
- it is necessary to ensure the removal of combustion products;
- Do not install a gas generator from main gas running on liquefied fuel in the basement.
In addition, the requirements are for fuel and piping:
- To use the devices, a certain pressure inside the main pipeline is necessary . Such an indicator should be in the range from 1.3 to 2.5 kPa. A valve is installed on the supply section of the main gas pipeline to shut off the gas flow.
- For liquefied fuels, the requirements are no different from the previous version. If a cylinder is used, it must be equipped with a valve and pressure regulator.
- The gas generator must be equipped with a manual start.
Device connection
Many people wonder: how to connect a gas generator to the main gas?
Such a process is uncomplicated, and with certain knowledge it can be carried out independently. No permissions are required.
Before connecting the gas generator to the main gas, it is necessary to coordinate all points with the gas supplying company. The list of actions is indicated in regulatory documents. The main ones are a certificate for the purchase of the device, as well as its technical passport. Further, the following issues are resolved:
- Making changes to an existing project.
- Conclusion of an agreement between the owner and supplier of gas to service the generator.
- Conclusion of a liability agreement for the fulfillment of certain obligations.
Reviews
Most consumers are satisfied that they have chosen this type of equipment.
A gas generator can work for a long time, since natural fuel does not wear out parts. In addition, such gas is cheaper than other types of fuel. Among the shortcomings note the need to collect additional documentation, which takes a lot of time and effort.
Conclusion
By installing a gas generator in the room, you can solve problems with the power supply.
To establish uninterrupted supply, you must purchase a powerful device that has an autostart function. When connecting to the main gas pipeline, all stages should be coordinated with the local gas service. The gas generator from the main gas, reviews of which are mostly positive, is an excellent device for both a small house and a large summer house.
