Gas-fired boiler equipment is available to customers in a wide range. Modern models have many differences among themselves both in design and in functional content. The introduction of new technological solutions, as well as the use of materials with improved performance indicators, makes it possible to regularly improve the level of technical characteristics of such units. This is confirmed by gas industrial boilers of domestic production. Russian enterprises produce high-quality equipment in this segment, focusing not only on the experience of foreign colleagues, but also on their own developments. It is worth noting the economic attractiveness of serial production of industrial boilers. Two factors contribute to this. First, the payback of products that are not cheap. Secondly, the demand for high-quality and efficient units.
Russian production of industrial boilers
Such characteristics as reliability, safety and functionality are usually applied to imported products. This is especially true for high-tech equipment. Howeverexamples of modern domestic enterprises show that our manufacturers can offer no less high-quality product. Conveyors and machine tools manufacture parts and components according to European standards, and technologists improve approaches to assembly processes. It is also worth noting that the production of industrial gas boilers in Russia, as a rule, is complemented by design services. This means that already at the assembly stage, the customer can count on the complete compliance of the equipment with the requirements and characteristics of a particular boiler house. This is especially important when considering the capacities that industrial and commercial units operate with.
Aggregate device
Most of the industrial models are designed for heating industrial buildings, workrooms and workshops. The design of boilers is also subject to these tasks. Its main element is the core burners. As a rule, a group of parallel rods is used, each of which has holes for the removal of the air-fuel mixture. In the process of mixing with air, a flame is formed, which evenly distributes heat over the entire area. Also, the device of an industrial gas boiler may include a water-tube heat exchanger, which heats up as a result of the combustion of the gas mixture.
There are also more complex units that are equipped with flare gas burner elements. The peculiarity of such models is that the entire basic designtogether with the fan is installed on the front side of the case. In the boiler itself there is a nozzle, which, in fact, acts as a source of flame and heat propagation. On the market, industrial gas boilers with flare burners are available in two-pass or three-pass versions. The most powerful of them are capable of heating water up to 115 ºС, as well as producing high-temperature steam. At this point, it is worthwhile to take a closer look at the two main varieties of such equipment - steam and water-heating models.
Steam models
This category of boilers is designed to generate steam. Most plants that use steam in their process require high pressure. Therefore, the performance of such equipment is made up of temperature and pressure indicators. For the most part, gas-fired industrial steam boilers are units that, through fire-tube structures, generate steam with a capacity of at least 0.25 t / h. Depending on the requirements of the enterprise, you can choose models with more power. As a rule, the maximum reaches 55 t/h. Pressure indicators, in turn, can be up to 30 bar, and temperature conditions - up to 300 ºС. Modern models are distinguished by the ability to work on various types of liquid and gaseous fuels. When choosing, it will not be superfluous to take into account the additional provision of equipment in the form of deaeration devices, dispensers and bubblers.
Water heating models
Models with hot water supply are symmetricalheating surfaces, but, as in the case of steam units, they operate on the principle of one- or multi-pass through the combustion product. At the same time, it is worth noting the versatility and versatility that industrial gas boilers are endowed with. The photo below, in particular, illustrates a hot water model that can operate not only on a gas fuel source, but also on a diesel engine.
When choosing such boilers, it is important to pay attention to the material of manufacture. In many respects, the reliability of the equipment, its safety and, as a result, the price depend on it. In some cases, such characteristics of the operation of water heating devices as the pressure level (maximum is approximately 16 bar) and heat output, which varies on average from 0.7 to 35 MW, come out on top.
Market assortment
At the moment, most of the models available on the market belong to foreign brands. These are, for example, units from the German manufacturer Bosch, which supplies models with the ability to work on both gas and liquid fuels. Also noteworthy are the Babcock Wanson models with a maximum power of up to 1757 kW. For large enterprises, it is worth noting the products of the Belgian company Prestige. It produces installations from several hot water boilers, characterized by high reliability and working life.
In turn, Russian-made gas industrial boilers are available in linescompanies "Turbopar", "Gorgaz" and "Aguna". The factories of these enterprises are engaged in serial production, including units of increased power up to 3.6 MW. Models are distinguished by the presence of automatic systems, a variety of designs and the ability to adapt specifically to the requirements of the installation site.
Maintenance details
The long-term use of boiler equipment depends not only on the working resource provided by the manufacturer. To a large extent, it is determined by maintenance - its quality and frequency. Maintenance measures include maintaining the chimney in optimal condition and carrying out regular inspections of all flue systems. No less important is the cleaning of industrial gas boilers, for which the burner is located on the door. In this state, it can open to the left and right to allow cleaning. This operation should be carried out regularly, but taking into account the intensity of operation of the equipment.
Operating life
Subject to the manufacturer's recommendations, gas equipment can serve an average of 15 to 20 years. Again, the working life depends on many factors, including the materials used and the conscientiousness of the maintenance. In this regard, the service life of industrial gas boilers until the first cleaning is also important. Typically this period is 3000 hours.difficult to overestimate, but it should be produced at large intervals - about once every 3 years.
Reviews about boilers
Gaseous fuel boilers are evaluated by consumers according to different criteria. First of all, this is performance - for example, most foreign models demonstrate an operating pressure that is quite close to the officially declared one. At the same time, domestic gas industrial boilers have already established themselves as safe, functional and at the same time aesthetically pleasing equipment. However, most models from major Russian manufacturers are deprived of the main advantage of our products - a lower price compared to imported counterparts. Also, the weaknesses of the gas boilers on the market include the need to purchase an external boiler and problems with the installation and operation of the thermocouple.
Conclusion
Gas heating equipment is beneficial in many ways. First of all, it is the economic feasibility of using gaseous fuel. It is this factor that has determined the relevance of replacing models operating on solid fuel sources. However, one should not overestimate industrial gas boilers, since the nature of their work imposes a number of requirements for manufacturers and direct users. These are mainly strict safety standards that determine the increased strength characteristics of the structure.equipment. For users, in turn, restrictions of a different kind are imposed - in terms of the nuances of content, operation and maintenance.

Natural gas is formed by mixing various gases in the earth's crust. In most cases, the depth of occurrence ranges from several hundred meters to a couple of kilometers. It is worth noting that gas can form at high temperatures and pressures. In this case, there is no access of oxygen to the place. To date, gas production has been implemented in several ways, each of which we will consider in this article. But let's talk about everything in order
