  1. “Where are we going?”Derek BradleySchool of Mechanical Engineering, University of Leeds British Section Combustion Institute: “Limits in Combustion Systems” Oxford 2006

  2. Fusion ignition and burning • International Thermonuclear Experimental Reactor (ITER) • Start-up 2016 • Full power operation 2021

  3. Energy and GHG Analysis

  4. Selected Areas • New Fuels. • High Pressure. • Flameless Combustion. • Very Big Fires and Explosions. • Electrical Fields.

  5. Problems of high pressure modelling and experiment

  6. H2-air, f= 0.4, T = 365K, 0.1 MPa

  7. H2-air, f= 0.4, T = 365K, 1.0 MPa

  8. H2-air burning velocities at 1.0 MPa and 365K

  9. Extinction stretch rates

  10. Ignition delay times, 4 MPa, f = 0.5

  11. Well-stirred Reactor

  12. Aachen Burner

  13. Scale of hazardous releases • 1986 Chernobyl, H2 explosions, plus 27,000 GJ graphite, at 20 MW. • 1988 Piper Alpha, burn rate 6.8 GW (17% average UK electricity generation rate). • 1989 Ufa, 100,000 GJ. Devastating explosion. • 2005 Buncefield, 1.3 GJ. Soot dispersion.
