Gasification of Simplex briquets: briquet production. Vol. 1. Final report

Technical Report · Fri Apr 01 04:00:00 EST 1983

OSTI ID:5730479

A 7-ton/hr briquetting plant was installed at International Briquetting in Baltimore, Maryland, and used to produce 360 tons of Simplex briquets from Pittsburgh No. 8 seam, Champion No. 1 mine caking coal and shredded, air-classified Baltimore County refuse. The production of these briquets was funded by the Department of Energy, through the US Bureau of Mines, and a consortium comprised of the New York State Energy Research and Development Authority and the Empire State Electric Energy Research Company. This report describes the briquetting plant and discusses the problems that were encountered in producing the briquets. The following modifications are recommended for future Simplex briquetting plants: drying equipment should be installed on the RDF feed system to ensure that the RDF moisture is below 18%; the crushed coal must be dried to less than 4% moisture to ensure its free flow in the bins; magnets should be installed above the coal and RDF feed conveyors to remove any tramp metal; a 3/4-inch screen should be installed over the coal feed bin to remove any oversize rocks or lump coal; the RDF handling system and turbulizer discharge to the press should all be enclosed for dust control (the enclosures should be vented to a baghouse); only heavy duty apron conveyors should be used where belt conveyors are needed; briquetts should be cured if they are going to be stored in containers where they might sweat; and a screen with 1 1/4-inch openings should be used to remove the fines from 2 1/4-inch briquets (this screen should be sufficiently large to prevent briquets from crowding together on the screen).
