Gas block-modular boiler-houses: equipment, construction, installation

Heating - this is one of the most important engineering systems, without which there can not do any industrial, residential or household construction. Without it you will simply freeze in winter. To provide the population with heat, whole boiler houses are built, which can work on different types of fuel. However, their erection requires a lot of time and is quite expensive. Gas block-modular boiler houses make it possible to avoid these problems. In this article you will have the opportunity to consider all the features of the presented structure.

What constitutes a construction

Gas block-modular boiler houses are specific engineering structures, the main function of which is heating of the coolant to provide heat and hot water supply in residential single-storey or multi-storey buildings, industrial plants, and residential buildings.

Connect this design to central or individual heating mains. Transportation of the structure can be carried out using rail or road transport. In order to prevent the theft of the component nodes of such a boiler house, during the transportation it is sewn with a false sheet of metal.

Different fuels can be used to operate the structures. Most often, their work can be based on gas boilers of sufficiently high power.

Product design

Gas block-modular boiler houses in their composition have such components:

1. Boilers. Their number depends on the capacity of the station.

2. Technological equipment.

3. Main fuel supply system.

4. Electrical equipment.

5. Pumps.

6. Combustion system.

7. Device accounting system.

8. Water treatment plant.

9. Automatic control system, security and alert.

Such nodes have a standard boiler room. Naturally, different manufacturers provide different equipment for the presented equipment. Other systems may be present in the design.

Product Advantages

Gas block-modular boiler houses have such advantages:

- They can significantly reduce the heating fee, since the operation and installation of such a structure are relatively inexpensive.

- There is no need for the construction of capital buildings. A small basement is enough. The fact is that the dimensions and weight of the module are not very large.

- Quick installation. To install the boiler is usually enough for 5 days.

- Fast entry of all units into operation. Naturally, you need to check all nodes before starting.

- All equipment inside the module is carefully protected against external negative factors.

- All devices are of high quality.

- It is possible to set those system settings that are necessary for the user.

Principle of operation and scope of application

Modular boiler plants are used for hot water supply and heating of schools, kindergartens, hospitals, production workshops, utility rooms, agricultural warehouses, apartment houses. In addition, they can provide ferry to those enterprises, which it needs to manufacture products.

As for the principle of work, it is very simple. Water is poured into the boilers, which heats up as the fuel burns. This process lasts until the temperature of the coolant reaches the established rate. Then the liquid flows through the pipeline into the consumer system.

After the water has given part of the heat, it returns to the boiler room again. The heating process is repeated again. As you can see, there is nothing complicated here.

Classification of structures

Such modular boiler installations can be distinguished:

1. Type K. They can operate on several fuels, the main of which is natural gas.

2. Type C. Such structures operate on solid fuel.

3. Type G. Boilers of this type can work on both natural and liquefied gas.

Features of manufacturing and transporting the structure

Block-modular gas boiler houses, photos you can carefully consider in the article, together with all the equipment is completely manufactured in the factory. That is, you no longer have to worry about buying and installing individual nodes.

The frame itself of the module is made of steel pipes, which have a rectangular cross section. They are connected by welding. The base is a platform, the floor of which is assembled as a sandwich panel.

Further in the block all necessary equipment is installed. It should be taken into account that the roof and the walls to the base are fixed with bolts or screws. Doors and windows in the module are usually aluminum and they open outward.

Product Specifications

To date, block-modular construction is very common. However, before you buy the presented design, you need to consider its technical features:

1. The capacity of the equipment: 0.4-28 MW.

2. Type of fuel: natural or liquefied gas, coal.

3. Temperature to which the coolant can be heated: 60-95 degrees.

4. Number of boilers: 1-3 pcs.

5. Diagram of boiler house: single- or double-circuit.

6. Warranty from the manufacturer: more than 25 years of impeccable service.

7. Efficiency: about 98%.

8. Voltage in the network: 220/380 V.

9. Hot water temperature: 60-80 degrees.

If you want to install block-modular gas-fired boiler houses, technical characteristics are the main parameter of choice. After all, the productivity and efficiency of the structure depend on them.

Features of choice and rules for operating the structure

The production of block-modular boiler houses provides for a large number of different models. An inexperienced person to understand them is quite difficult. Therefore, during the purchase try to be guided by such criteria of choice:

- Power and heating capacity of the installation. It all depends on the area of the heated room.

- Number of boilers. The standard design provides only 2 units, although there may be more.

- The number of blocks. It depends on how large the heated building is.

- Fuel type. It all depends on your capabilities.

- Presence of additional parameters. This can include a graph of temperatures, voltage monitoring in the network, coolant flow per day or week, and others.

- The cost of the module. Its price ranges from 900,000 rubles.

- Reputation of the manufacturer and user feedback. These parameters will help you really not make a mistake and choose high-quality equipment. Naturally, it is better to give preference to proven brands.

Regarding the use of special requirements there. It is only necessary to periodically clean the equipment from scale and contamination. To perform this work you may need from several days to a week. Cleaning is best done in the summer, when the equipment does not work, but is on preventive maintenance.

Module Mounting Features

The construction of block-modular boiler-houses consists of several stages:

1. Designing. Here it is necessary to observe all necessary safety rules, since the object represents a potential explosive and fire hazard. The project is coordinated with SES, architecture, Gospozharnadzor, Technadzor and other bodies.

2. Production of blocks.

3. Transportation of the product to the installation site.

4. Installation of the boiler room.

5. Connection of all necessary communication systems, arrangement of the chimney.

6. Adjustment of the module, correction of defects, test run.

Installation of a modular boiler house has some features. To begin with, the construction site will need to be prepared: cleaned of debris, pour the foundation, bring the engineering communications. Further, the blocks are mounted on the hardened base. If several modules are needed, they are connected by means of bolt ties.

The next stage of installation is the connection and connection of pipelines, their connection between the units. After this, the roof and walls of the structure are installed. The next step is the fixing of additional elements and a chimney. Lastly, the module is connected to the networks. After this, it is necessary to check the reliability of all fasteners and make a blank start. If everything is ok, the unit is ready for use.

What are the nuances of building a boiler house?

It should be noted that the presented units represent an increased danger. This means that they require special permission and other documents to install them. So, you will need to collect such papers:

- A list of those devices and equipment that are located in the module.

- List of all routine maintenance works on installation and connection of the unit.

- Instructions and documents in which planned work and maintenance of equipment are recorded.

- Technical passport for all equipment that will be installed in the boiler room.

- Instructions for operating the machine as a whole and its individual components.

- Passport of the BMK.

- A copy of Rostekhnadzor's permission to operate the boiler house.

- Certificate of conformity for installed equipment.

In principle, half of these papers are provided to you by the manufacturer, since it produces a complete installation.

That's all the features of block plants for heating buildings. Despite all the safety guarantees from the manufacturer, we can not neglect the rules of boiler operation. Good luck!
