Method and apparatus for recovering preheater coal fines

Patent ·
OSTI ID:6376512
Coal fines developed from the processing of coal through a preheating system are accumulated in a secondary cyclone system. The coal fines, at an elevated temperature, are mixed with a hydrocarbon organic binder and compressed into larger particles of sufficient structural integrity and mass to be fed directly through pneumatic pressure coke oven coal charging lines without significant size reduction, resulting in the elimination of fine coal build-up in coke oven standpipes and charging mains as well as overloading of the charging system.
