BIOMASS PULVERIZATION DEVICE, AND BIOMASS/COAL CO-COMBUSTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a biomass pulverization device in which a biomass raw material can be pulverized efficiently and stably and to provide a biomass/coal co-combustion system.

SOLUTION: The biomass pulverization device includes: a pulverization device body 13 having a raw material supply pipe 12 for supplying the biomass raw material 11 from above in the vertical axis direction; a pulverization table 14 on which the biomass raw material 11 is placed; a drive 15 for rotary driving the pulverization table 14; a pulverization roller 16 which moves linked with the rotation of the pulverization table 14 and pulverizes the biomass raw material 11 by pressing force; a blowing means for jetting a conveying gas 18 which forms an ascending flow upward from below on the outer circumferential side of the pulverization table 14 and pneumatically conveys the pulverized biomass raw material 17; a sorter 19 which is arranged on the inside of the top part of the pulverization device body 13 and used for sorting the biomass powder 17 accompanying the conveying gas 18; and a blowing gas introduction section 21 for supplying a blowing gas 22 toward the central part of the pulverization table 14 to promote the movement of the biomass raw material 11.
