Nearly, 60.5% of the coal particles reach the furnace exit in 4 s or lesser with a burner tilt of − 15°, as compared to 68% particles which reach the exit when the burner tilt is + 15°. Nearly, 20% of the coal particles spent between 10 and 20 s inside the furnace for − 15° tilt compared to 12% for a + 15° tilt.
