Gas generator from main gas: advantages, types, installation and photo

The gas generator from the main gas is the most common source of power. Of course, there are devices that operate on a different fuel. But they have a number of shortcomings.

The gas generator on the main gas practically does not make noise in operation, and also does not throw harmful substances into the environment. This device is easy to install and use.

Advantages

Among the positive aspects of gas generators is:

1. Operation of the device for a long time. The generator works until the fuel in the main pipeline runs out. To be able to work more, install an additional balloon system. It is this indicator is the main, in comparison with other equipment.
2. Low cost of cubic meter of gas, in comparison with other types of fuel. In addition, fuel can be in cylinders for unlimited time, unlike alternative sources.
3. 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.
4. Ecological compatibility. During its operation no harmful substances are released.

disadvantages

Like all devices, the gas generator on the main gas has minuses:

1. Increased explosion hazard of fuel. Various explosions and fires appear more than with the use of other devices. Therefore, it is necessary to provide additional transportation conditions.
2. Collection of documentation. To use a gas generator on the main gas, you need to obtain a permit, and also develop a project. Its cost will be much higher than the device itself.
3. In the room where the generator will be located, it is necessary to provide for exhaust ventilation.
4. When sub-zero temperatures appear, the fuel cylinder must be transferred to a warmer room.

Types of devices

In residential areas, you can use two types of generators. They are reserved and permanent.

The gas generator of the first type can work up to 20 hours. Cooling apparatus is by air. It can function more time. But at the same time its motor resource will be reduced. The generator can only function when it is in a cooled state. Therefore, most people use it when power is cut off.

If it is necessary 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 can be switched on and off independently. Therefore, it can cool down at these intervals. When this happens, inverters, along with 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 home on main gas

Two types of gas are used in the operation of this equipment. It is liquefied and main. In the first case, fuel is consumed from cylinders, and in the second - from the main pipeline. There are such devices that are able to function on another type of fuel, for example, methane.

Generators with liquefied fuel are recommended for use in the installation of a boiler in a house.

With a generator power of 6 kW, a 50-liter cylinder will last for 20 hours.

The main gas pipeline, which is connected to the house, is an advantageous source of food. Before installing it, you need to know the pressure in the pipeline. At a low value, such a generator for home gas will not function at high power. Before you connect it, you need to obtain permission from the relevant company.

Gas generator selection

To choose the right element for living space, you must consider the following characteristics. Fuel consumption, power, voltage, etc. So, let's consider what are the capacities of this equipment:

• 5-6 kW - this device is suitable for a small apartment house to hold 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 with the help of liquid cooling; Most of these devices are used in country houses or cottages;
• More than 25 kW - such powerful devices I use for production purposes in small enterprises.

As for the indicator, such as voltage, there are single-phase and three-phase gas devices. The first type is used to supply electric power to any household appliances with a voltage of 220 V. The second type, most often used in country houses or cottages for mixed electricity supply with a voltage of 220-380 V.

If three consumers are not connected to the device when using a three-phase type, then a single-phase automation system can be used.

The same can be done with a single-phase view, that is, to install three-phase automation and use the device for three consumers.

When choosing a gas generator, it is worth paying attention to the electric start and the automatic system. These functions are responsible for the automatic turning on and off of the equipment. In addition, the gas generator from the main gas with the auto start has an oil sensor, which protects it from the occurrence of breakdowns.

Installation

As a rule, such devices are equipped with a special protective cover. To perform installation of equipment, the following conditions are necessary:

• The temperature in the room should be above 0 ° C, if this condition is not met, then it is necessary to make the insulation;
• In the room must be provided with supply and exhaust ventilation;
• You need to take care of the removal of combustion products.

To date, there are such models that can be installed on the street. It is for this that they are equipped with a special casing. Their dignity is that they will not take up space in the room. In addition, they will function on the street even at negative temperatures and precipitation. It can work at -30 ° C. The cost of such equipment reaches 200,000 rubles. This price is much higher than that of analogues on diesel fuel with the same characteristics. But such a system quickly pays off if there is a gas heating boiler in the house.

Arrangement of premises

Typically, these devices are installed in the basement, boiler room or other comfortable room. The element can work only under the action of positive temperatures. The place must comply with all technical requirements for boiler houses:

• The room volume should be more than 15 m3;
• Must be provided for intake and exhaust ventilation;
• It is necessary to ensure the evacuation of combustion products;
• It is impossible to install a gas generator from the main gas operating on liquefied fuel in the basement.

In addition, the requirements are imposed on the fuel and the pipeline:

1. To use the devices, there must be a certain pressure inside the main pipeline. Such an indicator should be in the range from 1.3 to 2.5 kPa. At the feeding section of the main gas pipeline, a valve is installed, which serves to shut off the gas flow.
2. For liquefied petroleum, the requirements are no different from the previous version. If a cylinder is used, it must be equipped with a valve and a pressure regulator.
3. The gas generator must be equipped with a manual start.

Connecting the device

Many people ask themselves: how to connect a gas generator to the main gas?

Such a process is not difficult, and if you have certain knowledge, you can do it yourself. At the same time, no permits will be required.

Before connecting the gas generator to the main gas, it is necessary to reconcile all the points with the company supplying the gas. The list of actions is specified in the normative documents. The main of them is a certificate for the purchase of the device, as well as its technical passport. Further, the following questions are solved:

1. Making changes to the current project.
2. Conclusion of an agreement between the owner and the supplier of gas on the maintenance of the generator.
3. Conclusion of a contract on liability for the performance of certain obligations.

Reviews

Most consumers are happy that they chose this type of equipment.

The gas generator can work for a long time, since natural fuel does not wear out the parts. In addition, such gas is cheaper than other types of fuel. Among the shortcomings noted the need to collect additional documentation, which takes a lot of time and effort.

Conclusion

Having installed a gas generator in a room, you can solve problems with electricity supply.

To establish an uninterrupted supply, you must purchase a powerful device that has an autostart function. When making the connection to the gas main, all stages should be coordinated with the local gas service. The gas generator from the main gas, reviews about which in the majority are positive, is an excellent device, both for a small house and for a big dacha.
