Effects of Slag Compositions on the Rate of Methane-Stream Reaction

摘要

For the effective heat recovery from molten slag by utilizing a chemical reaction, rates of the methane- steam reaction on the slag surface were studied for thirteen slag samples, in which effects of mass ratio of CaO to SiO_2(CaO/SiO_2 ratio),and concentrations of wustite (FeO) and sulfur in slag on the reaction rate Were systematically examined in the slag temperature range from 1473 to 1823 K.
