Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct. It is used commercially as a form of waste treatment and has been tested ...
STEEL SLAG Material Description. ORIGIN. Steel slag, a byproduct of steel making, is produced during the separation of the molten steel from impurities in steelmaking furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
Common pollution control equipment on coalfired power plants and the byproduct wastes produced by each. Boiler slag is produced in coalfired power plants that use wetbottom boilers. It forms from melted minerals left over from coal combustion. This molten ash is quenched with water to form a solid, black, glassy waste product, called slag.
slag used for this purpose. • Pelletised or expanded slag has a vesicular texture (like volcanic rock) and is most commonly used as a lightweight aggregate. If finely ground it also has cementitious properties. In some countries, up to 80% of the cement contains granulated BF Using slag prevents it going to landfill as waste, saves

Waste with a lot of inorganic material won''''t yield as much gas. Because of this, some plasma facilities sort through garbage before feeding it into the system. The solid byproduct from the gasification process is called slag. The weight and volume of the original waste material is dramatically reduced.

Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and fluegas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.
Slag is a partially vitreous byproduct of smelting ore to separate the metal fraction from the unwanted fraction. It can usually be considered to be a mixture of metal oxides and silicon, slags can contain metal sulfides (see also matte) and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve ...
