APPARATUS TO CONTROL STEAM PRESSURE OF REHEAT STEAM SUPPLY CHAMBER IN COAL DRYER

摘要

The present invention relates to an apparatus to control steam pressure of a reheat steam supply chamber to improve a drying efficiency of coal by controlling steam pressure to form consistent injection pressure of reheat steam for transferred coal inserted into a transferring apparatus in a multi-stage dryer drying coal using the reheat steam. The present invention comprises: a first coal dryer wherein a second flue gas chamber is installed to collect flue gas on a first chain; a second coal dryer wherein a fourth flue gas is installed to collect flue gas; and a coal drying apparatus comprised of inserting primarily dried coal in the first coal dryer into the second coal dryer for the coal to secondarily be dried.;COPYRIGHT KIPO 2015
