ABSTRACT:
In a vacuum housing (1), an inner duct (17) is disposed. Quadrupole magnets (superconducting coils) (4) is placed around the inner duct (17) is excited by a DC power supply (10). Quadrupole magnets (4) are cooled by liquid helium contained in a helium housing and outer tubes (2, 3) and is brought into a superconducting state. Pulverized coal X is ejected together with air Y from a header (11) through piping (12) and a valve (13) to a baffle plate (14). Pulverized coal is made to fall into the inner duct (3). Paramagnetic materials such as ash are attracted by magnetic force to the tube and are then collected by a collection tube (26). Combustible diamagnetic materials are collected by a combustible collecting tube (18) extending in the central axis. Intermediate materials are collected by an intermediate collection tube (23) and are put back to the head (11) through a bypass tube (25). There are no mechanical parts in the inner duct (3). Consequently, rotation loss and eddy-current heating are prevented.
