Modeling Efforts

Annular shaft kiln (ASK) with five burners at each top and bottom levels (total of 10 burners). Our CFD analysis reveal flow and temperature imbalances which were corrected to optimize fuel efficiency, improve temperature distribution and product quality as a result.

Geometry of annular shaft kiln (ASK) showing five burners at the top level and bottom levels, i.e. total of 10 burners for the whole ASKG
Temperature distribution at the lower set of burner tube reaches a maximum
of about 1890K
Top view cross section area along the axis of the lower burner tube where flame spreads nearly the whole tube.  This is an indication that most of the combustion takes place in the burner tube attaining maximum of about 2180 K.
