Message summary:
Superfine dry powder fire extinguishing system and gas fire extinguishing system are currently the most commonly used automatic fire extinguishing systems, so is the ultrafine dry powder fire extinguishing system a gas fire extinguishing system? Nianhai Fire Fighting describes the difference between ultra-fine dry powder fire extinguishing system and gas fire extinguishing system from the two fire extinguishing principles and fire extinguishing states.

Superfine dry powder fire extinguishing system and gas fire extinguishing system are currently the most commonly used automatic fire extinguishing systems, so is the ultrafine dry powder fire extinguishing system a gas fire extinguishing system? Is there a necessary connection between the two? The difference between the two is explained by Nianhai Fire Fighting.

I. Gas fire extinguishing system

A gas fire extinguishing system is a fire extinguishing system in which the fire extinguishing agent is stored in a gas or liquid state in a pressure vessel, and the gas (including steam and aerosol) is sprayed during fire extinguishing. It can form a uniform gas concentration in all directions in the space of the protection zone, and at least keep the fire extinguishing concentration to reach the immersion time specified in the specification, so as to extinguish the space and three-dimensional fire in the protection zone. The gas fire extinguishing system is composed of a gas fire extinguishing device, a gas fire extinguishing controller, a fire detector, an audible and visual alarm, a gas release indicator, an emergency start and stop button, an external power source, and a fire power source.

气体灭火系统

Common gas fire extinguishing systems mainly include heptafluoropropane gas fire extinguishing system, high pressure carbon dioxide fire extinguishing system, IG541 mixed gas fire extinguishing system, fire detection pipe gas fire extinguishing system, etc. I have written this article before, and interested friends can move to " What are the common fire gas extinguishing systems? " This page.

Okay, far away. Next, please follow Xiaobian to see the specific situation of the ultra-fine dry powder fire extinguishing system.


Second, ultra-fine dry powder fire extinguishing system

The ultra-fine dry powder fire extinguishing system uses ABC ultra-fine dry powder as the fire extinguishing agent. The ultra-fine dry powder is non-toxic, harmless, does not cause damage to the protected object, and has no irritation to human skin and respiratory tract. Superfine dry powder fire extinguishing system is composed of superfine dry powder fire extinguishing device, gas fire extinguishing controller, fire detector, sound and light alarm, deflation indicator, emergency start and stop button, peripheral power supply, starting components, fire power supply and display panel, etc. composition. Hanging superfine dry powder fire extinguishing device is the most commonly used type of superfine dry powder fire extinguishing device, while hanging superfine dry powder fire extinguishing device is divided into two categories: temperature-controlled superfine dry powder fire extinguishing device, and electric control ultrafine dry powder fire extinguishing device.

超细干粉灭火系统

The pressure storage temperature-controlled ultra-fine dry powder fire extinguishing device is driven by nitrogen. When the ambient temperature rises to a set nominal value, the valve on the fire extinguishing device automatically opens to release the ultra-fine dry powder fire extinguishing agent to extinguish the fire.

The piezoelectric storage ultra-fine dry powder fire extinguishing device can be connected to the gas fire extinguishing controller, and can output a feedback signal during the injection. The composite fire signal is detected by the detection device and sent to the gas fire extinguishing controller. The controller confirms and outputs the command signal. The command signal activates the fire-fighting power through the repeater to open the valve to the fire-extinguishing device and release the ultra-fine dry powder fire extinguishing agent to extinguish the fire.

3. Is the ultra-fine dry powder fire extinguishing system a gas fire extinguishing system?
In summary, the gas fire extinguishing system is a kind of fire extinguishing method that sends out gas by high pressure. The gas fire extinguishing systems currently in use are in accordance with the Montreal Protocol, colorless, odorless, low toxicity, good insulation, and no secondary pollution. In addition, the clean gas with zero ozone depletion potential (ODP) meets the requirements of environmental protection, and will not cause pollution to fire objects after fire extinguishing.

The ultra-fine dry powder is also non-toxic, harmless, does not cause damage to the protected objects, and has zero ozone depletion potential (ODP). Objects have a certain degree of fouling and dust pollution, and are also difficult to clean. Generally, they are not suitable for objects of precision instruments.

气体灭火系统,超细干粉灭火系统

Both belong to different automatic fire extinguishing systems in terms of fire extinguishing agent filling and fire extinguishing status. Therefore, the ultra-fine dry powder fire extinguishing system is not a gas fire extinguishing system, but both have the same advantages in fire extinguishing and both have an irreplaceable role.


Whether the protection zone chooses a gas fire extinguishing system or an ultra-fine dry powder fire extinguishing system, this needs to be judged according to the situation of the on-site protection zone, but you can not worry about this. A service provider focusing on fire protection solutions in key protection zones like Nianhai Fire Protection will When designing the scheme, comprehensively consider the various situations of the protected area, and design a suitable fire extinguishing scheme for you.
