    Accurate Prediction of Sintering Temperature in Rotary

    Jul 08, 2018 The Sintering Temperature (ST) in the burning zone of the alumina rotary kiln determines the quality of the alumina clinker directly and the energy consumption. What is more, the ST is a key controlled parameter to the alumina rotary kiln. In this paper, a kind of Phase-Space-Reconstruction-based (PSR-based) prediction methods are proposed to accurately predict the ST. After comparative
