High-expansion foam fire extinguishing device for coal mines
High-expansion foam fire extinguishing devices for coal mines are mainly used to extinguish fires in underground mine tunnels, surface areas, and confined underground architectural spaces. They are suitable for fires involving coal, wood, oil, and similar materials. For fires in narrow terrains that are difficult to approach or locate, rescue can be carried out from a safe distance. High-expansion foam can quickly cover the fire source, cutting off the air supply to the fire scene. It vaporizes in the combustion area, absorbing a large amount of vaporization heat, providing insulation and cooling effects. At the same time, it releases a large amount of steam, diluting the oxygen content in the combustion area, thereby achieving suffocation extinguishing.

Fuel Oil Inert Gas Foam Generator for Mining
The inert gas foam generator for mining is an advanced technological device primarily used for fire suppression in underground coal mines. It can rapidly inert the fire zone, effectively prevent gas explosions, and significantly reduce or eliminate the risk of residual fire re-ignition. This device integrates inert gas and high-foam technologies, featuring dual functions of isolation cooling and releasing suffocating inert gases, ensuring more thorough fire extinguishing and quickly restoring safety to the work area. The device supports compatibility with inert gas and inert foam, can monitor oxygen levels in real time, and adjust gas composition, enhancing automatic protection functions during water shortage and power failure. Additionally, it is equipped with a secondary combustion device to ensure that carbon monoxide levels remain low even when oxygen concentration decreases. The device uses imported oxygen sensors that can be used long-term without replacement.

Fuel Oil Inert Gas Generator for Mining
The mining fuel inert gas generator is a fire extinguishing and explosion prevention device specially designed for underground working environments such as coal mines. The device operates based on the combustion technology of an aviation turbojet engine. Through the rapid oxidation reaction of fuel in a specially designed combustion chamber, it produces inert gases mainly composed of nitrogen (N2), carbon dioxide (CO2), and carbon monoxide (CO). These inert gases are cooled by water jackets and flue spray to become wet inert gases that meet fire extinguishing requirements, used to extinguish underground fires and suppress gas explosions.
