The design of gas fire extinguishing installations (GSP) is carried out on the basis of a specialist's study of many parameters of the building, including quite specific aspects:

• dimensions and design features of the premises;
• number of premises;
• distribution of premises by fire hazard categories (according to NPB No. 105-85);
• the presence of people;
• parameters of technological equipment;
• characteristics of HVAC systems (heating, ventilation, air conditioning), etc.

In addition, the fire extinguishing project must take into account the requirements of the relevant rules and regulations - so the extinguishing system will be as effective as possible in fighting fires and safe for people in the building.

Thus, the choice of the designer of the gas fire extinguishing installation should be taken responsibly, it is better if the same contractor is responsible not only for the design of the facility, but also for the installation and further maintenance of the system.

Technical description of the object

A gas fire extinguishing installation is a complex system that is used to extinguish fires of classes A, B, C, E in enclosed spaces. The selection of the optimal GFFS (gas extinguishing agent) option for the UGP makes it possible not to be limited only to those rooms where there are no people, but also to actively use gas fire extinguishing to protect facilities where service personnel may be.

Technically, the installation is a complex of devices and mechanisms. As part of a gas fire extinguishing system:

• modules or cylinders that serve to store and supply GFFS;
• distributors;
• pipelines;
• nozzles (valves) with a locking and starting device;
• manometers;
• fire detectors that generate a fire signal;
• control devices for UGP control;
• hoses, adapters and other accessories.

The number of nozzles, the diameter and length of pipelines, as well as other parameters of the UGP, are calculated by the master-designer according to the methods of the Norms and Rules for the design of gas fire extinguishing installations (NPB No. 22-96).

Drawing up project documentation

The drafting of project documentation by the contractor is carried out in stages:

1. Inspection of the building, clarification of customer requirements.
2. Analysis of initial data, performing calculations.
3. Drawing up a working version of the project, approving documentation with the customer.
4. Registration of the final version of the project documentation, which includes:
   • text part;
   • graphic materials - the layout of the protected premises, the available technological equipment, the location of the UGP, the connection diagram, the cable routing;
   • specification of materials, equipment;
   • detailed estimate for installation;
   • work sheets.

The speed of installation of all equipment, as well as reliable and efficient operation of the system, depends on how competently and fully the UGP project is in the future.

Gas extinguishing module

For storage, protection from external influences and release of GFFS to eliminate the fire, special modules of gas fire extinguishing are used. Outwardly, these are metal cylinders equipped with a locking and starting device (ZPU) and a siphon tube. Those models in which liquefied gas is stored, in addition, have a device for controlling the mass of the GFFS (it can be either external or built-in).

The cylinders usually have an information plate, which is filled in by the person in charge or the UGP maintenance master. The following data must be entered on the plate regularly - the capacity of the module, the working pressure. Also, the modules should be marked:

• from the manufacturer - trademark, serial number, compliance with GOST, expiration date, etc .;
• working and test pressure;
• the mass of an empty and charged cylinder;
• capacity;
• dates of tests, charges;
• name of GOTV, its weight.

The activation of the module in case of fire occurs after the receipt of a signal from the manual start devices or the control and monitoring security and fire device to the starting device (CP). After triggering the PU, propellant gases are formed, creating excess pressure. Thanks to this, the ZPU is opened and the fire extinguishing gas comes out of the cylinder.

The cost of installing gas fire extinguishing

The UGP designer must carry out a preliminary calculation of the installation cost.

The price will depend on several factors:

• the cost of technological equipment - modules, including components and the required number of GEF, control and monitoring devices, detectors, displays, cabling;
• the height and area of ​​the protected premises (or premises);
• the purpose of the object;
• type GOTV.

after discussion and approval with the client, they will be spelled out in the contract.

As a result, we get a job, and our client - a gas fire extinguishing system with a guaranteed high degree of reliability and quality.

Gas fire extinguishing is the most effective and, in many cases, the only way to automatically extinguish a fire (ignition). Gas extinguishing agents have been used in fire extinguishing systems for many years - they began to be widely used in Europe back in the 1950s. Gas has many advantages - it is most often an environmentally friendly substance that effectively extinguishes fires and does not harm property and interiors.

Modern gas fire extinguishing systems are truly unique. If a few years ago we knew only about a few varieties, then today new generations of gaseous extinguishing agents used in automatic fire extinguishing systems make it possible to speak of themselves as absolutely safe, environmentally friendly products that quickly evaporate from the atmosphere.

The area of ​​application of gas fire extinguishing systems is wide - they are used wherever the use of water, powder or foam is undesirable or impossible - at facilities where there is a lot of electronic computing equipment (server, computer centers, hardware), where even a short-term power outage can lead to extremely serious consequences (for example, on airplanes and on ships), as well as in premises where securities or works of art are stored - archives, libraries, museums, art galleries.

List of design works

Choosing a specialist

The use of the latest gas fire extinguishing systems requires a number of preparatory and design work, on which the flawless operation of the entire automatic fire extinguishing system as a whole largely depends.

The design of gas fire extinguishing should be carried out by specialists, since all calculations are made in accordance with the rules established by law. The design of gas fire extinguishing systems is based on the analysis of several parameters: the number of rooms, their size, as well as the presence of suspended ceilings and partitions, the area of ​​doorways, the temperature regime at the facility, the air humidity in the room, the presence and mode of work of personnel are taken into account.

Based on these data, the required number of modules / tanks with gas is calculated, the diameter of the pipelines through which the gas will be supplied to the fire site, as well as the number and size of holes in the nozzles that spray the gas.

Equipment selection

The advanced technologies and improved developments of the 3M company have made it possible to create an absolutely safe, environmentally friendly product of a new generation - the gas substance Novec 1230. The composition contains non-corrosive components with excellent dielectric properties.

The gaseous substance is not absorbed into surfaces that are sensitive to moisture, it evaporates quickly, as a result of which there is no damage to valuable property, for example, when extinguishing a fire, archival materials, electrical equipment, computers, as well as objects of art are not damaged by the Novec 1230 gas substance used for fire extinguishing.

A mandatory requirement of the current standards is the calculation of the need to organize openings to relieve excess pressure, the integration of the AUGPT into the building, the organization of gas exhaust from the protected premises after extinguishing a fire. All these complex calculations are performed according to approved methods and require special engineering knowledge.

Methodology for calculating the parameters of AUGP for extinguishing by volumetric method

1. The mass of the gas extinguishing composition (Mg), which must be stored in the AUGP, is determined by the formula

M G = Mr + Mtr + M 6 × n, (1)

Where Мр is the estimated mass of the GOS, intended for extinguishing a fire in a volumetric way in the absence of artificial ventilation of air in the room, is determined: for ozone-safe freons and sulfur hexafluoride according to the formula

Мр = К 1 × V P × r 1 × (1 + К 2) × С Н / (100 - С Н) (2)

For carbon dioxide according to the formula

Мр = К 1 × V P × r 1 × (1 + К 2) × ln [100 / (100 - С Н)], (3)

Where V P is the estimated volume of the protected premises, m 3. The calculated volume of the room includes its internal geometric volume, including the volume of a closed ventilation, air conditioning, and air heating system. The volume of equipment in the room is not deducted from it, with the exception of the volume of solid (impenetrable) building fireproof elements (columns, beams, foundations, etc.); K 1 is a coefficient that takes into account the leaks of a gas extinguishing agent from cylinders through leaks in the valves; K 2 is a coefficient that takes into account the loss of a gas extinguishing composition through leaks in the room; r 1 is the density of the gas extinguishing composition, taking into account the height of the protected object relative to sea level, kg × m -3, is determined by the formula

r 1 = r 0 × T 0 / T m × K 3, (4)

Where r 0 is the vapor density of the gas extinguishing composition at a temperature of T o = 293 K (20 ° C) and an atmospheric pressure of 0.1013 MPa; Tm is the minimum operating temperature in the protected room, K; С Н - standard volumetric concentration of GOS,% vol. The values ​​of the standard fire extinguishing concentrations of GOS (C H) for various types of combustible materials are given in Appendix 2; K z - a correction factor that takes into account the height of the object relative to sea level (see Table 2 of Appendix 4). The remainder of the waste water treatment plant in pipelines М МР, kg, is determined for AUGP, in which the nozzle holes are located above the distribution pipelines.

M tr = V tr × r GOS, (5)

Where V tr is the volume of AUGP pipelines from the nozzle closest to the installation to the end nozzles, m 3; r GOS - the density of the residual GOS at the pressure that exists in the pipeline after the end of the outflow of the estimated mass of the gaseous fire-extinguishing composition into the protected room; M b × n is the product of the remainder of the GOS in the battery (module) (M b) of the AUGP, which is accepted according to the TD for the product, kg, by the number (n) of batteries (modules) in the installation. In rooms in which, during normal operation, significant fluctuations in volume (warehouses, storage facilities, garages, etc.) or temperature are possible, it is necessary to use the maximum possible volume as the calculated volume, taking into account the minimum operating temperature of the room. The standard volumetric fire extinguishing concentration С Н for combustible materials not listed in Appendix 2 is equal to the minimum volumetric fire extinguishing concentration multiplied by the safety factor of 1.2. The minimum volumetric fire extinguishing concentration is determined according to the method described in NPB 51-96. 1.1. The coefficients of equation (1) are determined as follows. 1.1.1. Coefficient that takes into account leaks of a gas extinguishing composition from vessels through leaks in the valves and uneven distribution of the gas extinguishing composition over the volume of the protected room:

1.1.2. Coefficient that takes into account the loss of a gas extinguishing agent through leaks in the room:

K 2 = 1.5 × F (Sn, g) × d × t POD ×, (6)

Where F (Cn, g) is a functional coefficient that depends on the standard volumetric concentration of C H and the ratio of the molecular masses of air and gas extinguishing composition; g = t W / t GOS, m 0.5 × s -1, is the ratio of the ratio of the molecular masses of air and GOS; d = S F H / V P - room leakage parameter, m -1; S F H - total area of ​​leakage, m 2; H is the height of the room, m. The coefficient F (Cn, g) is determined by the formula

F (Cn, y) = (7)

Where = 0.01 × C H / g is the relative mass concentration of GOS. The numerical values ​​of the coefficient Ф (Cn, g) are given in reference annex 5. 2. The time of release into the protected room of the calculated mass of the GOS, intended for extinguishing a fire, should not exceed a value equal to: t POD £ 10 s for modular AUGP, using as GOS freons and sulfur hexafluoride; t POD £ 15 s for centralized AUGP, using freons and sulfur hexafluoride as GOS; t POD £ 60 s for AUGP using carbon dioxide as GOS. 3. The mass of a gas extinguishing agent intended for extinguishing a fire in a room with a working forced ventilation: for freons and sulfur hexafluoride

Mg = K 1 × r 1 × (V p + Q × t POD) × [CH / (100 - CH)] (8)

For carbon dioxide

Mg = K 1 × r 1 × (Q × t POD + V p) × ln [100/100 - CH)] (9)

Where Q is the volumetric flow rate of air removed by ventilation from the room, m 3 × s -1. 4. Maximum overpressure when supplying gas compositions with leaks in the room:

< Мг /(t ПОД × j × ) (10)

Where j = 42 kg × m -2 × C -1 × (% vol.) -0.5 is determined by the formula:

Pt = [CH / (100 - CH)] × Pa or Pt = Pa + D RT, (11)

And with a leaky room:

³ Mg / (t POD × j ×) (12)

Determined by the formula

(13)

5. The release time of the WTP depends on the pressure in the cylinder, the type of the WTP, the geometric dimensions of the pipelines and nozzles. The release time is determined when carrying out hydraulic calculations of the installation and should not exceed the value specified in clause 2. of Appendix 1.
