Abstract

The present invention has been designed to provide a solution to problems with conventional gasifiers which operate by having fuel introduced at one end of a gasification retort and gas and residues removed from the other end. This frequently results in powdered char residues being ejected with the gas, causing increased gas clean-up requirements. The present invention provides a solution to this problem by removing the gas from the retort at the fuel inlet end via the fuel feed system which is preferably a combined ram and scroll feed providing a supply of fuel under anaerobic conditions.

Claims

AMENDED CLAIMS received by the International Bureau on 21 jan 2009 (21.01.09)
: A system in which gases produced anaerobically in a gasifier retort are extracted at the fuel inlet end of the retort in which char and residue extraction is effected at the opposite end of the retort from the fuel input end by a scroll and rotary valve mechanism to avoid egress of gas and ingress of air. : A system as claimed in claim 1 in which the gases produced in the gasifier retort are extracted via the fuel feeder. : A system as claimed in any of the previous claims in which the fuel feed or feeds are cooled before discharge into the gasifier retort by means of one or more water jackets. : A system as claimed in claim 3 in which the gaseous products of the gasification process are cooled at discharge from the gasifier retort by means of one or more water jackets. : A system as claimed in any of the previous claims with provision for oils and/or tars to be fed into the gasifier retort via one or more tubes extending into the retort. : A system as claimed in claim 5 in which oils and/or tars are fed into the gasifier retort via a tube or tubes forming the core of a fuel feed scroll. : A system as claimed in claims 5 or 6 in which the oils and/or tars are produced in the gasification process.
