BIOMASS PELLET CRUSHER, AND BIOMASS-COAL MIXED-COMBUSTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a biomass pellet crusher and a biomass-coal mixed-combustion system capable of easily crushing a biomass pellet being subject to mixed-combustion with coal.

SOLUTION: The biomass pellet crusher includes: a moisture giving means 13 for giving moisture 12 to the biomass pellet 11; and a coarse-crushing means 14A for crushing the biomass pellet 11A to which the moisture 12 is given. The biomass pellet 11A to which the moisture 12 is given is temporarily stored in a hopper 16. During the storage time, the moisture 12 is spread to the entire pellet so as to be collapsed by itself, thus facilitating fine crushing by a fine crushing means 14B and improving the mixed-combustion rate of the coal 30.
