Fine fuel delivery system with remote drying and on site storage

摘要

A system and method of delivering dried fine fuel. Moist coal is extracted from a source and initially dried to a moisture content of five percent by a gas fired dryer plant. The initially dried fuel is then transported to a central processing site whereat the coal is pulverized and further dried and fed to a storage silo. Tractor-trailers receive the dried fine coal from the storage silo and transport same to the end user's site. The trailer is disconnected from the tractor and is utilized as a storage tank as the coal is withdrawn therefrom on an as-needed basis. A fuel injector coupled to a variable rate feeder is utilized in one embodiment to convey the dried fine fuel from the trailer to the burner.
