HP-CO2 Pressure Tube

The principle of high pressure CO2 tube was developed at the beginning of the 20th century. The basic idea was to get an efficient and secure material removal technique for mining and excavation purposes.
Unlike using explosives, high pressure CO2 doesn’t cause evacuation of certain parts of the mine. . The HP CO2 system doesn’t ignite fire damp and other explosive gas mixtures as well as ash deposits or other combustible materials.
The original HP CO2 system removes slag deposits from the outside through the furnace wall. A Pressure Tube, filled with liquid CO2, is inserted into the deposit. A heating cartridge evaporates the CO2. The expanded CO2 increases its volume by 600 times creating a powerful heaving force at pressures up to 3,000 bar. The outlet pressure is defined by a rupture disk. The gas backs away through the nozzle head into the slag and safely dislodges blockages or deposits.
