FURNACE FOR ACTIVATION OF CHARCOAL Russian patent published in 2009 - IPC C10B31/08 

FIELD: technological processes.

SUBSTANCE: invention may be used in recycling of cull wood. Prepared and fractionated charcoal is supplied to device 2 for loading. Natural gas and air are supplied to burner 11, being mixed and burned in combustion chamber 12. Combustion products including water vapor and CO₂ are supplied to upper part of heating chamber 3 and via openings 13 supplied to reactor cavity 1. Passing through charcoal combustion products heat it and enter in reaction with it. Then water vapor and CO₂ enter through openings 13 in opposite wall of reactor 1 in upper part of heating chamber 3. From source 9 of water vapor supply along manifold 10 saturated water vapor comes to lower part of chamber, via openings 13 it passes in reactor 1 and cools charcoal in its lower part prior to unloading.

EFFECT: possibility to use CO₂ produced in process of gas burning during charcoal activation, simple design of device and its higher efficiency.
