“…The radiant heat flux that was used during the test was 25 kW/m 2 . This was lower than the 35 kW/m 2 advocated by Irshad [12,13] for pine wood and this was because sweet sorghum released volatiles at a lower temperature than for pine wood, so the radiant heater in the cone calorimeter was reduced in power. This is equivalent to operating the gasifier at a lower temperature than for wood gasification.…”
