6 FAQs about [Liquid nitrogen explosion suppression and fire extinguishing device in energy storage cabin]

Does liquid nitrogen fire extinguishing work in utility tunnel?

The feasibility of liquid nitrogen fire extinguishing in utility tunnel was studied. It is found that the main mechanism of liquid nitrogen fire extinguishing is cooling and asphyxiation. Cooling during vaporization can suppress fire rapidly, and the asphyxiation completely extinguishes the flame.

Why is liquid nitrogen a fire extinguisher?

Liquid nitrogen (LN), an extinguishing agent characterized by its extremely low temperatures, liquefies at −196°C, forming a colorless and transparent liquid. Its remarkable capability to rapidly put out fires stems from its extreme coldness, leading to swift vaporization upon application of heat.

Can liquid nitrogen be used to extinguish underground mine fires?

According to previous experience, liquid nitrogen can be used to extinguish underground mine fires. Urban underground utility tunnel belongs to the enclosed underground space, in which a certain fire prevention zone is set up inside. In theory, the liquid nitrogen fire extinguishing system is adapted in utility tunnel.

What is liquid nitrogen (ln 2)?

As an efficient and environmentally friendly cryogenic extinguishing agent, liquid nitrogen (LN 2) is highly promising for fire extinguishing in narrow and long underground confined spaces. It is difficult to tackle the urban utility tunnel fire due to its complex and narrow structural characteristics.

Can liquid nitrogen extinguish a power cable fire?

Experiments show that liquid nitrogen can effectively extinguish power cable fires. And it is mainly achieved by asphyxiation. Cooling during the vaporization of liquid nitrogen can inhibit the development of the fire rapidly.

What is the extinguishing mechanism of liquid nitrogen?

The extinguishing mechanism of liquid nitrogen is discussed. The practical extinguishment calculation is analyzed. The extinguishing effect is related to the LN 2 release distance and direction.
