High Pressure/Enthalpy Intensified Combustor (High-pressure Hot Air Generator)

Constructed completely of metal, this combustor is designed for high pressure/highly intensified air generation.

  • Pressure:MAX. 1.0 MPa
  • Temperature:MAX. 1,000℃
  • Combustor load:0.58MW/m3 at pressure of 0.5Mpa (depending on operating pressure)

This air generator can reach the maximum enthalpy condition within two minutes after ignition because of its all metal construction. Furthermore, there is no risk of solid matter dispersion into the slipstream because of its non castable refractories construction.
