Gas block boiler house: description, characteristics, photo

The gas block boiler house is a transportable factory installation facility. It can operate on the basis of gas boilers, the power range of which varies from 200 to 10 000 kW. The hot water circuit can optionally be installed in addition. The structures have the necessary documentation, after installation and connection they are completely ready for operation. Their main difference is that the system can be transported.

Description

Gas block boiler house is an installation supplied by the customer in full factory readiness, with all necessary certificates and documents. Gas boiler plants are a modern solution for heating of administrative buildings, production halls, residential complexes and other objects of different purposes. A block boiler house is a device that is characterized by efficiency and high power, as well as transportability and operational comfort.

The installation is capable of performing several tasks at once, among them there are:

• hot water supply;
• heating;
• Ventilation.

Among other things, the consumer acquires ready-to-install boiler units. The advantages of such boilers are the availability of certificates and permits, factory readiness, automatic operation mode, as well as a wide range of boiler rooms. The consumer benefits and saves on the design work, he will be able to obtain different permits without much difficulty. The construction period of the boiler house can be significantly reduced, it will be possible to reduce the cost of design and installation work. If the consumer chooses such a block boiler house, he can reduce the cost of duty personnel, greatly improving the convenience of work.

For reference

On sale it is possible to meet modular boiler-houses in a wide range, they can have the necessary equipment and power. Among other things, they are economical. The use of boiler houses reduces the cost of heating, because the price of 1 kW of heat energy, which is produced by the boiler, will be lower than that offered by central heating systems.

Additional features

The modular boiler-house is a device that is completely ready for installation on the foundation, which is why it is possible to transport the object to the facility in an already assembled state. The consumer will only have to connect it to the gas main system and heating. For capital construction, the costs will be excluded, reconciliation work will be cheaper, because such products require compliance with technical conditions.

Boiler rooms can be combined into a cascade, while capacity is increased. Devices have a low weight, so they can be placed even on the surface of the roof of buildings. Their compact size attracts the attention of consumers, it distinguishes these devices from stationary boiler-houses. They can be produced in the form of ready-to-use products. For installation, a minimum permissions package is required, automation is guaranteed to be complete, therefore maintenance of the installation is not required. If necessary, the boiler room can be dismantled from the current location for use in another facility.

Specifications

Block gas boiler houses have certain characteristics, among them the use of gas as the main fuel, as well as the usual type of combustion. The heat exchanger is tubular and is made of steel. The operation of such a boiler house can be controlled using an electronic block device. The gas supply is automatic.

Design features

As the main process equipment, which is used in modular boiler houses, the steam or hot water boiler itself acts. Heat exchangers and a burner are used. For gas block boiler houses, gas equipment is used, which includes a filter, a gas pressure regulator, and emergency valves. The gas metering units and shut-off valves are not excluded.

The block boiler plant must contain pumping equipment; these can be network or circulating pumps, nutrients, make-up pumps, and anti-condensate pumps. For water treatment and water purification, appropriate equipment is used, and in the presence of hot water supply, the equipment of the circuit is used. For correct functioning of the system, control and measuring equipment is used, through which the system records temperature, electricity, steam, water and other parameters. The presence of chimneys and flues is important.

Principle of operation

In boiler plants, water is heated by heat, which is obtained from the combustion of fuel. The resulting heat heats the liquid that circulates in the heat exchanger. Pumping equipment is necessary for supplying water to feed pumps, and for the circulation of water in the heating system, appropriate equipment is used, which transports the liquid from the boiler room to the consumer and back. This involves circulating and network pumps.

In the combustion process, combustion products can form, they are discharged to the outside through chimneys or flues, getting into the atmosphere. In order to prevent the formation of scale and ensure the normal operation of the hydraulic system, it is necessary to purify water from mechanical impurities. For this, the boiler plants can have a deaerator, as well as purification filters. If there is water treatment equipment, this significantly extends the life of the equipment, reducing the risk of failure. Membrane or expansion tanks are required in the boiler room for liquid pressure and maintaining pressure in the system. They are needed to prevent water hammering.

Minimal equipment of gas boiler house

Manufacture of block boiler houses provides observance of one of three complete sets. If it is a minimum, the gas boilers made of steel are supplied in two pieces, this also applies to the boiler pumps. But the circulation pump is used in a single copy, like the chemical water treatment station. The same applies to each of the below mentioned components: a membrane tank, a unit for commercial water metering, electricity and gas, a modular boiler house, a control panel for burglar and fire alarms, control and shut-off valves.

Conclusion

There are special companies that are engaged in the design, manufacture and installation, as well as commissioning of the equipment described in the article. These include "Block boiler technology", which are engaged in the manufacture of block power plants in a separate building or in the energy complex. Typical solutions are developed and advantageously distinguish the company from alternative manufacturers of this segment. Typical options affect the timing and cost of the final product in a smaller direction, which is very much welcomed by consumers.
