Heating is one of the most important engineering systems, without which no industrial, residential or domestic building can do. Without it, you just freeze in the winter. To provide the population with heat, whole boiler houses are built that can run on various types of fuel. However, their construction requires a lot of time and is quite expensive. Gas block-modular boiler rooms 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 is the design
Gas block-modular boiler houses are specific engineering structures, the main function of which is to heat the coolant to provide heat and hot water in residential single-storey or multi-storey buildings, industrial enterprises, and residential buildings.
Such a design can be connected 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 components of such a boiler house, during transportation it is sewn up with a fake sheet of metal.
For the operation of structures, various fuels can be used. Most often, their work can be based on gas boilers of sufficiently high power.
Product Device
Gas block-modular boiler rooms incorporate the following components:
1. Boilers. Their number depends on the power of the station.
2. Technological equipment.
3. The main fuel supply system.
4. Electrical equipment.
5. Pumps.
6. The system of elimination of combustion products.
7. A system for recording the operation of devices.
8. Water treatment plant.
9. Automatic control, security and warning system.
These 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 rooms have the following advantages:
“They allow you to significantly reduce heating fees, since the operation and installation of such a structure are relatively inexpensive.”
- There is no need for the construction of capital buildings. Just a small foundation is enough. The fact is that the dimensions and weight of the module are not very large.
- Quick installation. It usually takes 5 days to install the boiler room.
- Fast commissioning of all units. Naturally, before starting, you need to check all the nodes.
- Partial or full automation of all building systems.
- Lack of constant monitoring of the functioning of the boiler room.
- No need to separately collect all the nodes of the system. The design is delivered to the installation site in a completely finished form.
- All equipment that is inside the module is carefully protected from 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 action and scope
Modular boiler plants are used for hot water supply and heating of schools, kindergartens, hospitals, production halls, utility rooms, agricultural warehouses, residential buildings. In addition, they can provide steam to enterprises that need it to manufacture products.
As for the principle of operation, 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 norm. Further, the fluid flows through the pipeline into the consumer system.
After the water gives up 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 facilities
We can distinguish the following modular boiler plants:
1. Type K. They can operate on several types of fuel, the main of which is natural gas.
2. Type C. Such facilities operate on solid fuels.
3. Type G. Boilers of this type can operate both on natural and liquefied gas.
Features of the manufacture and transportation of the structure
Block-modular gas boiler rooms, you can carefully consider the photo in the article, together with all equipment they are completely manufactured at the factory. That is, you no longer have to worry about buying and installing individual nodes.
The module frame itself is made of steel pipes that have a rectangular section. They are connected by welding. The base is a platform, the floor of which is assembled like a sandwich panel.
Then in the block all the necessary equipment is installed. It should be noted that the roof and walls are fixed to the base with bolts or self-tapping screws. The doors and windows in the module are usually aluminum and they open outwards.
Product Specifications
To date, block-modular construction is very common. However, before buying the presented design, it is necessary to consider its technical features:
1. Equipment power: 0.4-28 MW.
2. Type of fuel: natural or liquefied gas, coal.
3. Temperature to which the heat carrier can be heated: 60-95 degrees.
4. Number of boilers: 1-3 pcs.
5. Scheme of the boiler room: single or double circuit.
6. Warranty from the manufacturer: more than 25 years of excellent service.
7. Efficiency: about 98%.
8. Mains voltage: 220/380 V.
9. Hot water temperature: 60-80 degrees.
If you want to install block-modular gas boiler houses, technical specifications are the main parameter of choice. After all, the productivity and efficiency of the structure depends on them.
Features of the choice and rules of operation of the structure
The production of modular boiler houses provides for a large number of different models. An inexperienced person is difficult to understand. Therefore, at the time of purchase, try to be guided by such selection criteria:
- Power and heat output of the installation. It all depends on the area of the heated room.
- The number of boilers. The standard design provides only 2 units, although there may be more.
- The number of blocks. It depends on how big the heated building will be.
- Type of fuel. It all depends on your capabilities.
- Availability of additional parameters. This may include a temperature chart, monitoring the voltage in the network, coolant flow per day or week, and others.
- The cost of the module. Its price ranges from 900,000 rubles.
- Manufacturer reputation and user reviews. These parameters will help you really not to be mistaken and choose high-quality equipment. Naturally, it is better to give preference to trusted brands.
There are no special requirements regarding the use. It is only necessary to periodically clean the equipment from scale and dirt. You may need from a few days to a week to complete this work. It is better to carry out cleaning in the summer, when the equipment does not work, but is under preventive maintenance.
Features of module installation
The construction of modular boiler houses consists of several stages:
1. Design. 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 the SES, architecture, State Fire Inspection, Technical Supervision 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 room has some features. To begin with, the construction site will need to be prepared: clean up the debris, fill the foundation, bring engineering communications. Next, the blocks are installed on the hardened base. If several modules are needed, they are connected using bolt ties.
The next stage of installation is the supply and connection of pipelines, connecting them between the blocks. After this, the roof and walls of the structure are installed. The next step is to mount additional elements and a chimney. Lastly, the module is connected to networks. After that, you need to check the reliability of all fasteners and make an idle start. If everything is in order, the installation is ready to use.
What are the nuances of building a boiler room
It should be noted that the presented units represent an increased danger. This means that their installation requires special permission and other documents. So, you need to collect such papers:
- A list of those devices and equipment that are located in the module.
- A list of all maintenance work on installing and connecting the unit.
- Instructions and documents that record scheduled work and equipment maintenance.
- Technical passport for all the equipment that will be installed in the boiler room.
- The instruction manual for the unit as a whole and its individual components.
- BMK passport.
- A copy of the permission of Rostekhnadzor for the operation of the boiler room.
- Certificate of conformity for installed equipment.
In principle, half of these papers are provided to you by the manufacturer, since he is making a complete installation.
That's all the features of block installations for heating buildings. Despite all the safety guarantees from the manufacturer, the boiler house operating rules cannot be neglected. Good luck
