Tyer carburetion process

a carburetion process and gasifier technology, applied in the field of fluidized bed gasifiers, can solve the problems of insufficient processing of most starved-air gasifiers, inability to meet the requirements of use, and high cost, so as to achieve accurate control of fuel movement, reduce the pitch of the auger, and maximize the exposure to oxidation and/or gasification

Abstract

A means for improving prior art combined cycle combustor and / or gasifiers and / or plural thermodynamic cycle gasification systems by introducing and utilizing an auger for the continuous feeding, agitation, tumbling, advancement and discharge of heterogenous carbonaceous fuel. In addition to the aforementioned improvement, I have included provisions for Fontana's water gas shift reaction utilizing refectory embedded down-tubes that convey steam and oxygen into and through the chambers fluidized bed.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims subject matter disclosed in a provisional application filed Jan. 14, 2009, Ser. No. 61 / 205,055 entitled “Combined Cycle Gasifier” and a non-provisional application filed Feb. 20, 2009, Ser. No. 12 / 378,864, entitled “Improved Auger Combustor”, and is a continuation of a non-provisional application filed Jan. 19, 2010, Ser. No. 12 / 657,226, entitled “Tyer Carburetion Process.” The benefit under 35 USC 309(e) of the United States provisional application is hereby claimed, as are the priority benefits of the other applications named, the aforementioned applications being hereby incorporated herein by reference.BACKGROUND AND SUMMARY

[0002] The invention relates generally to fluidized bed gasifiers and to the production of gasified fuel via and / or in conjunction with the gasification of solid fuels in a fluidized bed gasifier featuring a rotating auger conveyor. More particularly, it deals with improvements to gasifiers th...

; OPERATIONAL DESCRIPTION

[0048]A carbonaceous fuel stream is introduced into the primary auger gasifier, advanced, agitated and tumbled by an auger, partially gasified and creates a flue gas stream and char product. The char product is collected from the primary auger gasifier, conveyor and delivered into the secondary auger gasifier. As said primary auger gasifier produces the flue gas stream that exits the flue gas discharge from the primary auger gasifier, said gases are directed to the boiler for steam production. After leaving said boiler, the flue gas stream, now an exit gas is cleaned and discharged. Concurrently, the steam stream also exiting the boiler steam drum, controlled by the steam control system directs steam stream to provide steam either into the steam turbine, which powers an electrical generator, and / or for auxiliary power. When required, for the water gas shift reaction, steam control system can direct both the steam stream into the secondary auger gasifier's do...
