01-09-2017· This was realized by moving the existing meal inlets to the riser duct height of about 8–10 m. As the kiln is equipped with an extended kiln riser duct (without tertiary air) it is possible to fire a significant amount of fuel in this kiln riser duct. Now about 25 % of the total fuel as SAF with main burner quality can be fired in the kiln riser.Get Detail
