FEEDER FOR INJECTING FIBROUS BIOMASS FUELS INTO A REACTOR AT ATMOSPHERIC PRESSURE OR INTO A PRESSURIZED REACTOR

摘要

A feed apparatus to feed a fibrous fuel into a pressurised vessel, the feed apparatus comprising an inlet into which the fuel can pass, an outlet to pass the fuel into the reactor, a barrel between the inlet and the outlet and through which the solid fuel passes, and at least one feeding roller to feed the fuel into and through the barrel, the construction and arrangement being such that the fuel forms a sealing plug in the barrel and said sealing plug is pushed through the barrel by virtue of the at least one feeding roller.
