T he r esult s reveal th at oil shale h as better ig ni tion f eatures and low er ignition temperature compared to coals . It s combust ion is m ainly the burning of volatile m atter so the [ 1] combustion inten sity is strong at ear ly stage but sig nif icantly re 4 750 du ced at the f ollow ing char burn out stage. T his sug gest s that oil [ 2] 5. 4 shale is not su itable f or pulv er ized combu stion due to it s slag ging f eatures and high ash content but is ideal f or flu idized bed boil ers.
