TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Method: The step (S20) and (S30) are performed by using disc-shaped or drum-type tumbling granulator, pug or paddle low-speed mixer granulator, Schugi (RTM: Vertical continuous mixer and agglomerator) mixer type, horizontal pin type or peg mixer type high-speed mixer granulator, fluidized bed granulator, centrifugal granulator, spray dryer, spray process of prilling tower or flash dryer, molding, piston, tablet or roll pressing confined pressure device, pellet mill or extrusion screw extruder. The hydrophobic coal-biomass granule type mixed fuel is produced using granulator, molding machine and/or extruder.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The step (S20) comprises mixing greater than 0 wt.% to less than 100 wt.% solid biomass powder and greater than 0 wt.% to less than 100 wt.% coal powder. The particle size of the mixed fuel is 4-100 mm. The step (S30) comprises adding greater than 0 wt.% to less than or equal to 50 wt.% binder. The step (S40) and (S50) are performed at 30-700 degrees C. The step (S50) is performed at 30-700 degrees C, preferably 200-700 degrees C. The mixed fuel is formed at atmospheric pressure to 10 MPa.
