Abstract

The invention relates to a method and to a system for homogenizing and controlling the solid fuels delivered pneumatically using dense flow conveyance to a gasifier for generating syngas, configured such that considerably homogenized feeding of the coal to the combustion chamber is enabled, wherein the short-term fluctuations are minimized and the gasification quality is thereby improved and control of the coal quantities to the combustion chamber are configured more effectively. Said object is achieved in that the fine-grained to powdered fuel is first delivered from a storage container (1) positioned below the combustion chamber level to a level above the combustion chamber level, and subsequently homogenized in a line directed downward toward the combustion chamber (4a, 4b).
