Gas-fired boiler equipment is available to customers in a wide range. Modern models have many differences between each other 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 raise 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
Features such as reliability, safety and functionality are typically applied to imported products. This is especially true for high-tech equipment. However, examples of modern domestic enterprises show that our manufacturers can offer at least a quality product. Conveyors and machine tools produce parts and accessories 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 full compliance of the equipment with the requirements and characteristics of a particular boiler room. This is especially important when considering the capacities with which industrial and commercial units operate.
Unit design
Most industrial models are designed for heating industrial buildings, workrooms and workshops. The design of the boilers is subordinate to these tasks. Its main element is rod burner devices. As a rule, a group of parallel-running rods is used, in each of which holes are provided for the removal of the air-fuel mixture. In the process of mixing with air, a flame is formed that evenly distributes heat throughout the area. Also, the device of an industrial gas boiler may include a water tube heat exchanger, which is heated by combustion of the gas mixture.
There are more complex units that are equipped with flare gas burner elements. A feature of such models is that the entire basic design, coupled with a 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 the spread of flame and heat. On the market, industrial gas boilers with flare burners are available in two-way or three-way versions. The most powerful of them are able to provide water heating to 115 º, and also to produce high-temperature steam. At this point, it is worthwhile to examine in more detail the two main varieties of such equipment - steam and hot-water models.
Steam models
This category of boilers is designed to generate steam. Most enterprises that use steam in the process require high pressure. Therefore, the performance of such equipment is composed of indicators of temperature and pressure. Mostly gas industrial steam boilers are units that generate steam with a capacity of not less than 0.25 t / h through fire tube structures. 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 º. Modern models are distinguished by the ability to work on various types of liquid and gaseous fuels. It will not be superfluous to take into account the additional equipment provision in the form of deaeration devices, dispensers and bubblers when choosing.
Hot water models
Models with hot water supply differ in the symmetrical arrangement of the heating surfaces, but, as in the case with steam units, they work on the principle of one-or multi-pass passage of the combustion product. At the same time, it is worth noting the multifunctionality and versatility that industrial gas boilers are endowed with. The photo below, in particular, illustrates a water-heating model that can work not only on a gas source of fuel, 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 consequence, the price depend on it. In some cases, such characteristics of the operation of water-heating devices as the pressure level (maximum is about 16 bar) and heat output, which varies from an average of 0.7 to 35 MW, come first.
Assortment in the market
At the moment, however, most of the models available on the market relate to foreign brands. These, for example, are 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 maximum power 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, gas-fired industrial gas boilers of Russian production are available in the lines of 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 Nuances
The long-term use of boiler equipment depends not only on the working resource laid down by the manufacturer. To a large extent, it is determined by maintenance - its quality and frequency. Among the maintenance measures, keeping the chimney in optimal condition and conducting regular inspections of all systems for the removal of combustion products stands out. 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 left and right, allowing cleaning. This operation should be performed regularly, but taking into account the intensity of operation of the equipment.
Service life
Subject to the manufacturer's recommendations, gas equipment can serve an average of 15 to 20 years. Again, the retention period of a working resource depends on many factors, including the materials used and the good faith during maintenance. In this regard, the lifetime of industrial gas boilers up to the moment of the first cleaning is also important. Usually this period is 3000 hours. The need for major repairs is difficult to overestimate, but it should be done at large intervals - about once every 3 years.
Boiler reviews
Gaseous fuel boilers are evaluated by consumers according to different criteria. First of all, it is productivity - for example, most foreign models demonstrate working pressure, 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 of the models from major Russian manufacturers are deprived of the main advantage of our products - a lower price in relation to imported analogues. Also, many attribute the weaknesses of gas boilers on the market to the need for 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 fuels. It is this factor that determined the relevance of replacing models operating on solid fuel sources of fuel. However, gas industrial boilers should not be overestimated, since the nature of their operation imposes a number of requirements for manufacturers and direct users. These are mainly strict safety standards that determine the increased strength characteristics of the equipment design. For users, in turn, restrictions of a different kind are imposed - in terms of the nuances of maintenance, operation and maintenance.
