Military Engineering — MineBurner UXO Clearance System

The MineB­urn­er is a patent­ed sys­tem devel­oped to dis­pose of explo­sive rem­nants of war using non-explo­sive com­po­nents or sub­sys­tems by com­bin­ing oxy­gen with liq­uid petro­le­um gas to pro­vide a high tem­per­a­ture cut­ting flame that burns through the case of a land­mine and ignites the con­tents. The flame has a tem­per­a­ture of 2,300° C and can pen­e­trate 3mm steel. Oxy­gen is obtained by pump­ing atmos­pher­ic air through a fil­ter to remove the nitro­gen. Liq­uid petro­le­um (cook­ing) gas is local­ly avail­able, there­by elim­i­nat­ing the require­ment to trans­port haz­ardous car­go to the mine­field. The MineB­urn­er and acces­sories are all air-trans­port clas­si­fied as non-hazardous.

The MineB­urn­er con­sits of the fol­low­ing reusable components: 

  • Bat­tery Charg­er Unit (1)
  • Field Mod­ule Unit (5)
  • Blad­der Assem­bly (2)
  • flame-proof cov­er for the Blad­der Assem­bly (3)
  • Blad­der Filler Unit (4)
  • Remote Fir­ing Unit

The remote fir­ing unit enables the oper­a­tor to ini­tial­ize the igni­tion from a dis­tance of 2km+ depend­ing on the use of repeater and the land­scape. And there is no line-of-sight required. For the increase of effi­cien­cy the oper­a­tor can use ten field mod­ules to burn ten tar­gets simultaneously. 

The blad­der assem­bly con­sists of three sep­a­rate blad­ders that store the gas­es. The first is filled with 0.5 liter liq­uid petro­le­um gas (LPG), the sec­ond with 2.5 liter Oxy­gen with up to 0.4 bar and the third with 2.5 liter com­pressed air to dri­ve the oth­er gas­es. All blad­ders con­tained togeth­er in strong stitched seam out­er cov­er. The oxy­gen and LPG hose from the blad­der assem­bly are con­nect­ed to the field mod­ule unit and from there the hoses with the igni­tion and flame detec­tion cables are lead­ing to the tar­get. The field mod­ule unit sounds a 10 sec­ond audi­ble alarm via its installed siren before the igni­tion and mon­i­tors and trans­mits the mea­sure­ments about the flame and gas mix­ture to the remote fir­ing unit.
