Scope and purpose
The main use of autonomous gas generators is related to their use. at various industrial sites. They can also be installed in civil and domestic facilities as the main source of energy supply. If there is no centralized electrical network at the facility or territory, the installation of this unit allows for a stable supply of electrical energy in the right quantity. If the object is electrified, the gas gas generator is used as a backup power source.
The low cost of fossil fuels largely contributed to the popularization of this equipment. It can operate on the basis of oil mine gases. Along with them, bio-raw materials are suitable for the operation of these plants. This allows you to get electricity at low cost. The advantage of such devices is their environmental friendliness. During work, they do not emit substances harmful to human health.
The principle of operation and design features
To ensure the normal operation of the gas autonomous generator and at the same time a high degree of performance, it is necessary that The following conditions:
- the ability to generate heat, which only happens when fuel is burned.
- conversion to mechanical equivalent of thermal energy. This is realized through the work of the heat engine.
Another transformation is the process of converting mechanical energy into electrical energy. This task is performed by means of the rotor and generator.
If we talk in general about the gas generator, then it represents something similar to a conventional electric boiler, which contains two combustion chambers. Each of them performs its task:
- Fuel loading and partial ignition occur in the primary chamber.
- The secondary chamber ensures complete generation of the incoming gas.
Pyrolysis process It occurs when the temperature is maintained at a level not lower than 1100 degrees and is supplied in sufficient quantity to the combustion chamber of oxygen. The result of the combustion process is the formation of gases containing a fraction of impurities that are cooled and purified. The process of their purification is carried out through special filters.
On the market, gas generators are presented in a large assortment. Along with overall models, compact installations are also available. As the main fuel, these devices use liquefied or natural gas. Devices that operate on liquefied gas, have more advantages, because you can install them even in areas where there are no suitable conditions for the operation of such units.
Types and types of devices
If we consider in detail the design of a pyrolysis generator designed to generate electricity, there are three types of this equipmentwhich differ only in the process of gas generation:
With the method of fuel supply associated features of each of these three types. They also differ in the type of fuel used during operation. So, devices of the first type work on bituminous fuel, which is coal or semi-coke.
Installations of the second type use resin material. Air is supplied from the side. This process occurs at high speed through special devices called lances. In other cases, air is supplied and gas is taken at different levels.
In the case of a direct gas generation process, the supply of natural fuel is carried out from the bottom, and in the upper part there is a gas intake. The reverse process occurs almost the same, only here fuel is supplied from above, and gas intake is from below.
If we consider compact models of gas generators designed to generate electricity, then they can be purchased at a price within 35,000 rubles. Installations having a similar cost are offered by Generac. They run on natural gas. By paying such money, the consumer receives equipment with a high degree of functionality and 2 kW minimum. Noticeably more expensive pyrolysis installation cost, which is understandable, taking into account the complexity of their devices and relatively large dimensions.
Domestic manufacturers of generators
Domestic companies also offer their products on the Russian market. Among them are the following: “EltEnergoEffekt”, “Soyuzenergo”, “AeMes”.
Popular brands are:
- FG Wilson;
The gas equipment for the production of electrical energy produced by these companies differs:
- environmental friendliness;
- availability of fuel.
If pyrolysis plants are a suitable option for a building owner, he can get them by paying serious money. However, they are worth it. The consumer receives the gas generator, which is characterized by high performance and has great power. For models of such installations, this indicator starts at 40 kW and may be higher.
If large-scale electricity production is required, the purchase of such installations is fully justified. Practical experience of using this equipment shows that they are inconvenient to use. At the same time and with their maintenance, there are certain difficulties. One of the problems associated with this equipment is the difficulty of controlling the level of humidity, which has a major impact on the combustion process.
Equipment that uses natural gas to operate requires less space and at the same time provides high performance. The advantage of such installations is that it is available on the market with various power indices. Therefore, the owner of the object can choose the installation in accordance with their needs. But without the drawbacks of such gas generators is complete. The use of such equipment is not suitable in all cases. However, if the choice is made in its favor, then there are no problems with it due to the automation of the work process.
Choosing a place for installation installation features
Pyrolysis devices, characterized by large dimensions, have several drawbacks. They do not have an attractive look and require ample space. Features of operation of this equipment force the owners of the facilities to allocate special rooms in which the gas generator is located. In this regard, installation of such gas generators on the basement or in the basement is permissible at household facilities. In the open air, they can only be positioned if the unit has a degree of protection a certain level.
Currently, gas generators and power plants are widespread among consumers. The profitability of their use is the main reason for the high popularity of this equipment. Most models of these installations are enclosed in a casing, thanks to which a sufficient level of protection of this equipment is ensured. When choosing an installation site, this feature is decisive. The presence of the housing allows you to remove restrictions on the placement of this equipment.
However, there is one point to which attention should be paid. Such installations should set on a flat surface. If this requirement is not fulfilled, the noise level will increase, and this negatively affects the comfort of living people. In addition, there is another drawback - the beating of parts together during the operation of gas generators increases, vibration level increases, which reduces the service life and premature wear of the main parts and nodes.
With regards to the pyrolysis boilers, experts recommend placing them on the site to which it is easiest to ensure the supply of fuel. Often, to provide the facility with electricity, modifications of gas generators are installed, which, along with work on natural gas support the reception of firewood up to 1.5 m. However, it is quite problematic to ensure the supply of solid fuel in conditions premises. When choosing an installation site, such a moment as the level of heat transfer of the equipment is taken into account, since during burning the temperature can reach up to 1400 degrees. The only exceptions are long burning boilerswhose combustion chambers have a thermal insulation layer.
Thus, if the operation of this equipment is organized correctly, the need for regular maintenance of the equipment will be minimized. The gas generator, in contrast to other installations for the production of electrical energy requires little attention, because the fuel does not burn completely. And this allows us not to think about the performance of work on cleaning the combustion chambers.
When selecting equipment for a stable power supply, it is necessary to pay attention to the power indicators. generator sets, as well as the effectiveness of their work in the field, especially if there are no centralized power grids. The important point is that the dimensions of the room in which the planned installation of the equipment must comply with the dimensions of the device. If the plans for the placement of the gas generator in the open air, then this question is not relevant.
Not all facilities have the ability to connect to electrical networks, and in some cases pWorks are conducted in the field and there is a need for electricity. In such situations, without such equipment as a gas generator can not do. The variety of models offered on the market is quite large, so each consumer can choose the equipment according to their needs.
Modern models are economical in operation and good functionality. They can be installed in a specially adapted room. Such plants can work on natural gas. When these units are used in the field, then as fuel liquefied gas is used. The power of this equipment may be different, so the consumer can choose the right equipment for their needs.
