Abstract
The invention relates to producing lump semicoke and can be used in metallurgy. Essence of the invention consists in that a method for producing said lump semicoke calls for using, as coal bed, coal having a fraction of 20-70 mm and air is supplied thru the coal bed with a relative blowing rate of 70-99.5 m 3 /m 2 ·hr according to a coal rank.
Claims
exact text as granted — not AI-modified1 . A method for producing lump semicoke comprising the thermal treatment of a coal bed in a vertical shaft-type apparatus on kindling from the side opposite air supply, characterized in that the coal bed used is represented by coal having a fraction of 20-70 mm and air is supplied thru the coal bed with a relative blowing rate of 70-99.5 m 3 /m 2 ·hr, in relation to a coal rank.
