PELLETIZED FUEL COMPOSITION AND METHOD OF MANUFACTURE

摘要

A pelletized fuel composition comprising coal fines in an amount of from 60 % to 80 % by weight, paper making sludge in an amount of from 10 % to 30 % by weight, and a shredded polymeric material in an amount of from 0.5 % to 15 % by weight. A method of manufacturing the fuel composition involving pelletizing at pressure of from about 1,000 psig to about 4,000 psig is also disclosed. An apparatus for processing the composition is shown in the Figure and includes a continuous mixer (25) and pellet mill extruders (40).
