Gasification Reactor an overview ScienceDirect Topics

The ‘clean cavern’ techniques were developed during the RM-1 trial in the USA (e.g. Boysen et al., 1990) to quench the reactor and remove any contaminants. The clean cavern technique involves flushing the cavity with water/steam to quickly reduce the temperature of the coal and stop contaminant formation via coal pyrolysis.

Lining (Refractory) an overview ScienceDirect Topics

Feb 01, 2011· When a common tap hole is used for both slag and alloy tapping, a post–tap hole cleaning step is required to obtain slag-free alloy and also alloy-free slag. The most common practice is to tap into cascading ladles, which results in the alloy collecting in the first ladle and the slag overflowing into a slag ladle or into a slag pit.

Active Tundish Slag Pyrometallurgy

slag is a barrier against reoxidation and thermal losses. By reconstructing tundish to a closed chamber with lid, argon gas shrouding and eventual heating system, tundish slag might be even ignored. The concept of “active tundish slag” aims definitely at improving of steel cleanliness by “tailoring” a proper tundish slag.

Low CO2 emission technologies for iron and steelmaking as

Aug 01, 2007· Titania slag is an important raw material for the production of TiO 2 pigment. Today’s practice is to reduce and smelt the iron in the ilmenite (FeTiO 3) in an electric furnace to produce hot metal for further steelmaking and TiO 2 slag. Feeding hot and prereduced material into the smelting furnace could save considerable electric power.
