Boiler Slag There are two types of wetbottom boilers the slagtap boiler and the cyclone boiler The slagtap boiler burns pulverized coal and the cyclone boiler burns crushed coal In each type the bottom ash is kept in a molten state and tapped off as a liquid

This gave rise to substitutes including coal slag An Occupational Safety and Health Administration investigation in 2010 uncovered a case cluster of suspected pneumoconiosis in four former workers at a coal slag processing facility in Illinois possibly attributable to occupational exposure to coal slag dust

blasting process seems to be a problem for waste management because of the waste disposal laws The shipyard has to follow a certain track to treat the waste generated depending upon whether it is toxic or not or hazardous or non hazardous Most commonly used abrasives are

of Copper and Coal Slag Abrasives By John Peart and Benjamin Fultz Bechtel Corporation Abrasives processed from slags have replaced silica sands in many steel fabrication shops because of their low free silica content Copper smelters and coalfired electric generating plants are 2 major material sources for these slag products

Coal liquefactionthat is any process of turning coal into liquid products resembling crude oilmay be either direct or indirect ie by using the gaseous products obtained by breaking down the chemical structure of coal

Flue Gas Desulfurization Material a material leftover from the process of reducing sulfur dioxide emissions from a coalfired boiler that can be a wet sludge consisting of calcium sulfite or calcium sulfate or a dry powered material that is a mixture of sulfites and sulfates

The copper slag processing facility was constructed on an old smelting site Smelting is the process of heating ore at high temperatures to remove impurities from the molten metal Inside the smelter furnace a layer of mostly iron silica and other impurities is formed and is known as ‘copper slag’

All bulk samples of finished product granules contained less than 1 silica supporting the claim coal slag may present less risk for silicosis than silica sand We note that the results presented here are solely from two coal slag processing facilities and more indepth air monitoring is needed to better characterize occupational exposure to coal slag dust metals and silica at similar facilities
