Slags sulfide capacities

This paper will be divided into three parts. First, the selection of slag compositions will be outlined. Second, sulfide capacity measurements of these slags will be discussed. Third, the desulfurizing potential of a slagging, cyclone combustor will be evaluated using these measurements. 

Sulfide capacities of the selected slag compositions were measured to rate the slags and to provide data for evaluation of the operation of a combustor with these slags.

The sihca dux combines with iron(II) sulfide and iron(II) oxide to form slag. The duidity of the slag, in which unwanted impurities dissolve, is controlled by the addition of limestone. Reverberatory furnaces have been largely replaced by more advanced smelting furnaces, which require lower energy input, have higher capacity, and produce higher sulfur dioxide content off-gas.
