A method for providing material to a gasifier. The method comprises providing a feedstock. A flow of the feedstock is formed. The flow is then delivered to a gasifier such that it provides a substantially airtight seal to the gasifier.

대표청구항 ▼

1. A method for providing material to a gasifier, said method comprising: providing a feedstock;forming a substantially continuous flow of said feedstock in an auger feeder, said auger feeder comprising an auger screw;delivering said substantially continuous flow of said feedstock from said auger feeder to an outlet tube, said outlet tube connected at an inlet end thereof to an outlet end of said auger feeder;providing at least one restrictor that extends inwardly from said outlet tube downstream from said auger screw and into said flow of said feedstock to cause said feedstock to form a substantially airtight plug of said feedstock in said outlet tube such that said feedstock continues to flow through said outlet tube, wherein each said restrictor is adjustable such that a respective position of each said restrictor is adapted to be adjusted relative to said outlet tube; anddelivering said substantially continuous flow of said feedstock from said outlet tube to a gasifier such that said flow of said feedstock provides a substantially airtight seal to said gasifier. 2. The method of claim 1 wherein said feedstock is solid waste material. 3. The method of claim 1 wherein said outlet tube is water-cooled. 4. The method of claim 3 wherein water is circulated around said outlet tube in a channel between an inner wall and an outer wall of said outlet tube. 5. The method of claim 3 wherein said outlet tube is configured to be split into a first tube section and a second tube section. 6. The method of claim 5 wherein water circulates from said first tube section to said second tube section through a fluid path external to said outlet tube, said fluid path adapted to be disconnected to enable said outlet tube to be split into said first tube section and said second tube section. 7. The method of claim 6 wherein water is circulated around said first tube section in a channel between an inner wall and an outer wall of said first tube section, through said fluid path, and around said second tube section in a channel between an inner wall and an outer wall of said second tube section. 8. The method of claim 1 further comprising the step of providing a gate, said gate in an open position adapted to allow said feedstock to continuously flow from said auger feeder to said outlet tube, and said gate in a closed position adapted to provide a substantially airtight seal between said auger feeder and said outlet tube and block said flow of said feedstock from said auger feeder to said outlet tube. 9. The method of claim 8 wherein said gate is adapted to be cooled by a flow of water in a channel between a first wall and a second wall of said gate. 10. The method of claim 1 wherein a plurality of said restrictors extend inwardly from said outlet tube into said flow of said feedstock to cause said feedstock to form said substantially airtight plug of said feedstock in said outlet tube such that there is said substantially airtight seal to said gasifier. 11. The method of claim 10 further comprising the steps of: providing coal prior to forming said flow of said feedstock;delivering said coal to said auger feeder; andadvancing said coal from said auger feeder to said outlet tube for delivery to said gasifier. 12. The method of claim 11 wherein said coal maintains suitable size characteristics for use in said gasifier. 13. The method of claim 1 further comprising the step of: circulating a fluid around said outlet tube in a channel between an inner wall and an outer wall of said outlet tube for cooling said outlet tube;wherein said feedstock is solid waste material. 14. The method of claim 1 wherein said feedstock is delivered to said gasifier at a rate of at least about 25 tons/hour. 15. The method of claim 14 wherein said feedstock is delivered to said gasifier at a rate of at least about 50 tons/hour. 16. The method of claim 15 wherein said feedstock is delivered to said gasifier at a rate of at least about 75 tons/hour. 17. The method of claim 1 further comprising the step of delivering said feedstock to a plurality of auger feeders to form said substantially continuous flow and at least one additional substantially continuous flow of said feedstock: wherein said feedstock is delivered to said gasifier at a rate of at least about 50 tons/hour. 18. The method of claim 1 further comprising the step of delivering said feedstock to a plurality of auger feeders to form said substantially continuous flow and at least one additional substantially continuous flow of said feedstock: wherein said feedstock is delivered to said gasifier at a rate of at least about 75 tons/hour.
