Glassy slag

Continuous casting slags. These slags have the approximate composition (CaO = SiO = 35% Al-O, = 7% Na O 4-15 and CaF 5-8 ). Olusanya - has reported that the absorption coefficients lie in the range (0.5 - 5 cm ) and thus could be appreciable in these slags. Values of were obtained for ten glassy-slags by Tay r and... 

Reasons for the low destruction rates include reduced operational availability due to a detonation inside the facility and buildup of a glassy slag material inside the liquid agent incinerator. The Army has developed design changes to address the mechanical difficulties however, some will not be tested until the disposal facility at Tooele Army Depot, Utah, begins operations. That facility is currently conducting nontoxic tests of the plant s systems. 

Granulated nickel slag is essentially an angular, black, glassy slag sand with most particles in the size range of -2 mm to 0.150 mm... 

Plagioclase feldspar (Na-Ca aluminosilicate), other than albite, stains red potash feldspar (microcline or orthoclase) stains yellow, and quartz and glassy slag are unstained. Calcite takes on various shades of pink and dolomite may be deep red. The particles are normally examined in immersion mounts, utilizing liquids of known index of refraction and a cover glass.

At the time being, a special incinerator is in construction for the treatment of soil contaminated with arsenicals. After a flotation process, soil wash containing the arsenicals goes to a plasma arc reactor where agents, carbon etc. are combusted and the soil is melted to a glassy slag containing some arsenic. 

Cyclone firing It refers to slagging combustion of coarsely pulverized coal in a cylindrical (cyclone) burner. Some wet-bottom boilers are not cyclone-fired. The primary by-product is a glassy slag referred to as boiler slag. 

The repowered plant air emission estimates are significantljr lower than the original power plant on the unit basis of pounds of emissions per million Btu feed coal or per MW-hr electricity generated. Furthermore, the absolute air emissions in tons per year are still lower even though the plant will increase from a cycling-load 100 MW unit to a base-load 265 MW unit. In addition, the only solid is a black, glassy, slag which is a non-leachable, sand-like material. The sulfur is recovered as a valuable liquid sulfur byproduct.
