In this paper, numerical simulations of the effects of the primary air and secondary air FGR (Flue Gas Recirculation) ratios in a lime rotary kiln on combustion characteristics, NOx generation, and limestone calcination degree were studied in detail. The results revealed that two distinct temperature peaks were observed along …

WHAT IS A LIME KILN? Rotary kilns are large steel tubes that are lined on the inside with refractory bricks. They are slightly inclined from the horizontal and are slowly rotated on …

One common use for rotary kilns is the production of lime (calcium oxide) by calcinating limestone, which requires significant heat to achieve – approximately 900 °C (1,650 °F). Such high-temperature processes must be handled carefully, and there are several problems that may arise if the kiln is not properly configured for this usage ...
