A carbonaceous fuel gasification system for a supercritical COpower cycle system includes a micronized char preparation system comprising a devolatilizer that receives solid carbonaceous fuel, hydrogen, oxygen, and fluidizing steam and produces micronized char, steam, hydrogen, and volatiles. An indirect gasifier includes a vessel comprising a gasification chamber that receives the micronized char, a conveying gas, and steam where the gasification chamber provides syngas, ash, and steam. A combustion chamber receives syngas and an oxidant and burns the mixture of syngas with the oxidant to provide heat for gasification and for heating incoming flows, thereby generating steam and CO. The heat for gasification is transferred from the combustion chamber to the gasification chamber by circulating refractory sand. A syngas cooler cools the syngas and generates steam and provides to a supercritical COpower cycle system that performs a supercritical COpower cycle for generating power.

All-steam gasification for supercritical COcycle system

A carbonaceous fuel gasification system for all-steam gasification with carbon capture includes a micronized char preparation system comprising a devolatilizer that receives solid carbonaceous fuel, hydrogen, oxygen, and fluidizing steam and produces micronized char, steam, volatiles, hydrogen, and volatiles at outlets. An indirect gasifier includes a vessel comprising a gasification chamber that receives the micronized char, a conveying fluid, and steam. The gasification chamber produces syngas, ash, and steam at one or more outlets. A combustion chamber receives a mixture of hydrogen and oxidant and burns the mixture of hydrogen and oxidant to provide heat for gasification and for heating incoming flows, thereby generating steam and nitrogen. The heat for gasification is transferred from the combustion chamber to the gasification chamber by circulating refractory sand. The system of the present teaching produces nitrogen free high hydrogen syngas for applications such as IGCC with CCS, CTL, and Polygeneration plants.

All-steam gasification with carbon capture

A method and apparatus for decarbonizing gases using pressure swing in a first and second pressure vessel that each comprise a fixed bed sorbent. Syngas and steam are received in the first pressure vessel. A carbonation reaction is performed in the first pressure vessel that reacts carbonaceous species in the received syngas with the received steam to produce carbon dioxide and hydrogen. Decarbonated syngas is exhausted from first pressure vessel. A calcination reaction is performed in the second pressure vessel to produce carbon dioxide. A vacuum is provided to the second pressure vessel that causes carbon dioxide to exhaust from the second pressurized vessel at a pressure that substantially follows the decomposition pressure line.

Provided herein are systems, methods and equipment that include Integrated Gasification Combined-Cycle technology to retrofit existing plants, that include, e.g., subsystems for separating char fines from syngas after it emerges from an internally-circulating fluidized bed carbonizer and injecting the char into the carbonizer draft tube as a fuel source. Efficiency and power generation are thus increased to the extent that inclusion of carbon capture systems are now possible for existing coal plants in order to significantly reduce carbon dioxide emissions.

An enclosed-rotor vertical-shaft rotary valve is used as an airlock to inject abrasive, fine, or sticky solids into pressurized air. The invention eliminates the effect of thermal expansion on the gap between the rotor and casing, thereby making it possible to obtain much smaller gaps than before. The smallness of the gaps makes it feasible to pump clean air into the gaps without interfering with the performance of the airlock. The clean air keeps dust-laden air from entering the gaps, which eliminates the erosion that has limited the usefulness of conventional rotary valves when handling abrasive powders. By the use of two vents and a dual-pressure purge-air system, the invention also greatly reduces the blowby of air into the entrance of the airlock, which has limited the usefulness of conventional rotary valves when handling very-small-particle powders. These benefits also accrue to the injection of sticky solids into pressurized fluids. The invention extends the pressure and temperature capability of airlocks, so they may be used to inject solids into fluids at lower instead of higher pressure and so they may be used with fluids other than air.

Vertical-shaft airlock

A rotary valve including a rotor assembly rotatable by a driver to cause material to be transferred from an inlet side to an outlet side of the rotary valve. The rotor assembly includes a rotor coupled to a shaft which rotates about an axis when driven by the driver. The rotor includes an outer tube, an inner tube, and a plurality of radial blades. The rotary valve includes a casing assembly for supporting the rotor assembly that includes an inlet for allowing the material to enter pockets of the rotor assembly and an outlet for allowing the material to exit the rotor assembly. The casing assembly includes an upper cap disposed at a top of the casing assembly that contains an opening for allowing the material to enter the pockets of the rotor assembly, a shaft opening, and a wiper assembly that removes material from the tops of the blades as the blades pass by the inlet opening. The rotary valve also includes a plurality of springs coupling a lower cap to the sleeve that serve to compress the rotor between the caps. The rotary valve includes a bearing assembly for rotatably supporting the rotor inside the casing assembly. The bearing assembly includes an upper bearing which separates the upper cap from the top of the rotor by a minimum gap, a lower bearing which separates the lower cap from the bottom of the rotor by a minimum gap, and bearing grooves in which the bearings are disposed.

A mechanism for the prevention of distributor plate pluggage by dust-laden gases in multistage fluidized-beds is disclosed. Slanted tubes are used to control the flow of gases into a fluidized bed, where the angle between the slanted tube and the distributor plate is less than the angle of repose of the bed solids.
