Open publisher page 0 citations

Abstract

By experiments adding different amounts Fe 2O 3,CaO,MgO,K 2O,Na 2O,SiO 2,Al 2O 3,P 2O 5,TiO 2 into blend coals and a lot of simulation tests with commercial blend coals in pilot coking oven, 169 groups of data were obtained. The order of ten ash main components in terms of effect on CRI and CSR was clarified by regression analysis. Then the calculation method for ACI(ash catalysis index) and mathematic model predicting CRI and CSR were established.
