Oxymat on-site nitrogen generators for mining and mineral processing.

Mine fire prevention is one of Oxymat’s key applications.

In the coal mines, nitrogen is primarily used to prevent mine fires and to inert abandoned areas of mines reducing oxygen level thus lowering limit of explosion.  The nitrogen generator can provide nitrogen at required flow & purity and can be placed stationary or as mobile unit to extinguish pit fire at reasonable cost.

The inert atmosphere is important by metal processing to inhibit unwanted oxidation.

We can provide you with a Oxymat gas generating plant according to your consumption profile at required quantity and purity, designed for harsh environment.

Benefits of using nitrogen in coal mining:

  • Inexpensive medium for inerting – Compressed air is needed for air separation to produce nitrogen in required purity and quantity.
  • Underground fire extinguishing – By reducing oxygen to below a level where burning is possible.
  • Non-aggressive unlike other firefighting sources – water, powder, foam – Nitrogen does not cause corrosion or any other harm such as other agents tend to. The consequences of using nitrogen are easily eliminated by just airing the premises.
  • Constant fire & explosion safe atmosphere – Nitrogen injecting in abandoned areas or mines eliminates the threat of fire or explosion.
  • The „Fire Triangle “- Oxygen, heat, and fuel are frequently referred to as the „fire triangle. “The important thing to remember is: Remove any one of these four elements and you will not have a fire or the fire will be extinguished. Essentially, fire extinguishers put out fire by taking away one or more elements of the fire triangle. What is easier than displacing oxygen with nitrogen and thereby eliminating the risks of fire.
