Description | 7/16" thick, 24" wide, 96"tall panels of OSB mounted to 1" thick Marinite board (new Marinite). Ignite using rectangular propane burner @ 60kW for ignition, burner shut off once then left on throughout remainder of experiment (turn off early to protect back side of panel apparatus). Heat flux gauges mounted flush with fuel surface |
