Experimental Devices for Burning Particles and Vaporizing Drops at High Pressure
Contact : Christian CHAUVEAU
High pressure chamberThis chamber is equipped with an electrostatic levitation unit allowing the study of particle combustion without contact. The ignition is ensured by a CO2 laser. • Maximum pressure : 12 MPa |

Types of particles
|
Different types of particles can be studied in this device : • Al, AL-Ni, Mg, Fe • Coal, lignite, petroleum coke The ignition delay and combustion time of these particles can be determined as a function of the parameters: pressure and composition of the ambient gas. |
