Test on pure hydrogen at EQR of 0.51

When hydrogen was injected the mixture self-ignited within the rig causing the auto-shutdown function (based on temp rise) to trigger. Gases were shut down. 2 sets of data were recorded (15 seconds apart). No obvious reason for auto-ignition so re-tried with same results. 3rd data set 15 minutes later.

Decided to re-try after removing rakes from expansion section (possible source of ignition) -  see test HRSG Test 34
