Abstract
A method of manufacturing a pelletized fuel including the steps of hydrolizing cellulose containing material to form a binder, mixing the binder with combustible fines including preferably coal fines and wood chips or saw dust in which the binder is about two percent to eight percent by weight of the mixture, and forming the mixture into pellets. The pellets are dried by subjecting them to a temperature sufficient to drive off substantially the water content thereof to provide pellets which are crush resistant and weather resistant and which may thereby by handled for use as a fuel such as in a boiler for generating steam.
Claims6
The method of manufacturing a pelletized fuel comprising:
- (1) hydrolyzing cellulose containing material to produce a binder;
- (2) mixing the binder of step (1) with combustible fines in which the binder is about 2% to about 8% by weight of the mixture;
- (3) forming the mixture in step (2) into pellets which may be burned as a fuel;
- and
- (4) curing the pellets from step (3) by subjecting the pellets to an elevated temperature of about 165.degree. C. in an environment wherein the pressure is not substantially greater than atmospheric pressure.
