Applications:

Inject nitrogen into the oxidation space of mining empty zone or fire zone to reduce the proportion of oxygen to less than 10% or 3%,to achieve fireproofing and blast-proof, such as:1. Eliminate danger of fire damp explosion.2. Reduce air leak effect. 3. Reduce temperature4. Prevent the coal from heating and self-ignite.Reduce burning intensity.
