Electrochemical energy storage fire extinguishing system

Can foam extinguishing agent be used in energy storage station fire?

DNV GL did not recommend the use of foam extinguishing agent in the fire of energy storage stations because the battery module fire required rapid cooling to dissipate heat. Compared with water, foam had more difficulty penetrating the gap of battery packs and cooling the insides of batteries. 4.3.4. Liquid Nitrogen

Which extinguishing agent is effective in suppressing Lib fire?

Russoa et al. compared the inhibition of CO 2, foam extinguishing agent, water mist, water, and dry powder extinguishing agent on LIB fire, and found that water and foam extinguishing agent might be effective in suppressing LIB fire. The comparison results are shown in Figure 13.

How does hydrogel fire extinguishing agent work?

The fire extinguishing time for a single battery is only 9 s, and the consumption is only 0.18 L. Hydrogel effectively reduced the height of the flame, dispersed the flame shape, and blocked the heat transfer between batteries through kinetic energy interference, water mist diffusion, and covering cooling. 4.3.3. Foam Extinguishing Agent

What is the primary and secondary fire extinguishing mechanism?

The primary fire extinguishing mechanism included heat absorption and cooling, mainly aimed at cooling the flame, wetting the surface of burning objects and forming a barrier to isolate external oxygen. The secondary extinguishing mechanism was the thermal radiation barrier and dynamic disturbance of the flame.

What is a gas fire extinguishing agent?

Gas Fire Extinguishing Agent Gas fire extinguishing agents have the advantages of no residue, environmental friendliness, and no damage to equipment.

How to reduce the fire and explosion hazards caused by LIBs?

In addition, to reduce the fire and explosion hazards caused by the TR of LIBs, the highly efficient extinguishing agents for LIBs are summarized. Finally, the early warning technology and fire extinguishing agent are proposed, which provides a reference for the hazard prevention and control of energy storage systems. 1. Introduction
