METHOD OF LIQUID FUEL COMBUSTION OBTAININGSLAG OF GIVEN COMPOSITION Russian patent published in 2009 - IPC F23B90/00 

FIELD: power engineering.

SUBSTANCE: invention relates to heat-power engineering and the construction industry and can be used for obtain obtaining slag glass-ceramics during fuel combustion in bubbled melted slag. Fuel combustion and obtaining slag of the given composition is carried out by bubbling oxygen-containing gas through a molten bath with the intensity of 1000-2700 nm³/h on 1 m³ of molten below tuyere and above tuyere zones, and together with the fuel simultaneously add "ЗШО", limestone and clay with the intention of obtaining homogenous melted slag, of the given composition, wt %: 62-67 CaO; 18-24 SiO₂; 4-7 Al₂O₃; 1.5-6.5 Fe₂O₃; 0.5-4.5 MgO; 0.4-1.2 K₂O; 0.3-1 Na₂O and SO₃<1.

EFFECT: obtaining melted slag of the given composition, suitable for direct obtaining of Portland blast-furnace slag cement which meets the standards of All-Union-State-Standard, creation of technology by ecologically clean, safe and with high economic efficiency.
