ABC® (International patent no. PCT/IB2010/051146) is the Cimprogetti vertical single shaft kiln with counter current flow arrangement and is the latest in the evolution of single shaft kilns. The kiln, thanks to its particular firing system, allows ABC® to produce the so called hard-burnt lime, with an optimal use of diverse limestone sizes and a variety of gaseous, liquid and pulverized solid fuels. The innovative technologies involved in the new firing arrangement achieve a substantial reduction in pollutant emission. KEY FACTORS suitable for gas, liquid, solid fuels highest availability and service life lower maintenance cost easy to operate high kiln temperature ABC® (Advance Burning Concept) kiln With the particular burner design of the the control of ABC®, the burning temperature makes this design the “must-have” technology especially for : soda ash and PCC industries; applications where a high CO -content in off-gases is 2 required. Traditional mixed-fired lime kilns may be replaced with the ABC® lime kiln. 5
