BIOMASS PULVERISATION DEVICE AND BIOMASS/COAL CO-COMBUSTION SYSTEM

摘要

Disclosed is a pulverisation device (13) equipped with: a raw material supply pipe (12) which supplies biomass raw material (11) from above in the vertical axis direction; a pulverisation table (14) on which the biomass raw material (11) is placed; a pulverisation roller (16) which moves in conjunction with the rotation of the pulverisation table (14), and which pulverises the biomass raw material (11) by pressing force; a blowing means which generates an updraft; and a classifier (19) which classifies the pulverised biomass powder (17). The pulverisation device (13) is provided with a blowing gas introduction section (21) which supplies blowing gas towards the central section of the pulverisation table (14), and which promotes the movement of the biomass raw material (11).
