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, the location where the biomass raw material (11) is pulverised; 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). A plurality of table grooves (31) are formed on the surface of a table liner (14b) of the pulverisation table (14) radiating towards the outer edge side of the pulverisation table (14) from the inner peripheral section thereof, and the tips of the grooves (31) are near the central section of the table liner (14b).
