PREPARATION OF FREE-BURNING COAL Russian patent published in 2014 - IPC C10L9/08 C10L5/00 C10L9/00

Abstract RU 2537151 C1

FIELD: process engineering.

SUBSTANCE: invention relates to a method of preparation of free-burning coal with the content of volatile substances not exceeding 16% whereat the said coal is heated to 200-395°C to destruct heat-sensitive coal lumps to be cooled and classified thereafter. Anthracite and/or hard coal are used as the free-burning coal. Heated coal is cooled at an ambient temperature.

EFFECT: stabilised grain size, simplified process, higher calorific value.
