METHOD FOR INHIBITING OCCURRENCE OF PYROLYSIS DEPOSIT IN PYROLYSIS GASIFICATION SYSTEM, AND PYROLYSIS GASIFICATION SYSTEM

摘要

This method for inhibiting the occurrence of a pyrolysis deposit in a pyrolysis gasification system includes: gasifying biomass (S2) through pyrolysis in a pyrolysis gasification furnace (5) to form a pyrolysis gas (G1) and a carbide (C) continuously; subjecting the pyrolysis gas (G1) and the carbide (C) to separation in a solid-gas separation unit (7); feeding an oxygen-containing gas (G3) to the separated pyrolysis gas (G1); and introducing the pyrolysis gas (G1) together with the oxygen-containing gas (G3) to a combustion furnace (6) through a pipe (9) which constitutes a pyrolysis gas line (8).
