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.

Mine Fuel Oil Inert Gas Generator
Product Introduction
The mine fuel oil inert gas generator is a fire extinguishing and explosion-proof device specially designed for underground working environments such as coal mines. The working principle of this device is based on the combustion technology of an aviation turbojet engine. Through the rapid oxidation reaction of fuel oil 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.
Used for extinguishing fires and suppressing gas explosions in coal mine underground areas. It produces low-oxygen mixed inert gas by burning kerosene, suitable for handling underground mine fires and goaf fires. In addition, this device can also be used for fire extinguishing and explosion prevention in closed or semi-closed spaces.
Product Features
- Oxygen content can be observed at any time, and gas composition can be adjusted. It improves the automatic protection device for water shortage and power failure.
- Equipped with a secondary combustion device, allowing it to maintain CO at a low level even when oxygen decreases. Uses imported oxygen sensors for permanent use without replacement.
- Uses the latest devices such as mine explosion-proof switches and automatic ignition. Operation is both safe and simple. It is the most practical fire extinguishing device for coal mines.
- The fire extinguishing effect is remarkable, capable of quickly extinguishing large-area open fires underground in coal mines, effectively suppressing gas explosions, and rapidly inerting the fire zone gases. It can handle open fires in tunnels as well as goaf fires.
- Uses ordinary civilian kerosene as fuel, which is low cost and easy to source.
- The equipment has a large gas production capacity per unit time, fast inerting speed in the fire zone, and after extinguishing, work can be resumed safely, quickly, and economically with low equipment loss rate.
