Annular shaft kiln for lime burning with kiln gas

The effects of increasing air excess ratio during the process of lime burning in an annular shaft kiln are specifically analysed. The paper presents a case of a remodelled annular shaft kiln, in which the air excess ratio can be reduced to its optimal level by recirculation of recuperator waste gas and its injection into the combustion chambers.

Air Pollution due to Lime and Brick-Kilns Environmental

Lime-kilns produce SO 2, CO about 50 percent un-burnt volatile matter of coal and lime­stone coal dust, emitting from the top layer of the kiln.Most of the kilns do not have any kind of stack for release of flue gases. Except for Belgian type kilns, the other kilns, namely, KVI, CBRI and country type vertical kilns have batch feeding twice a day.

Limepit Wikipedia

The burning process would last three to six days, without letup. After the burning was finished, the kiln would be left to cool for four to six days. The lime would then be taken out. The large lime blocks along the edge of the pit were considered of the highest quality, while the small pieces towards the center of the pit were considered grade B.
