    摘要： A system for use in a gasification system, comprises a solid pump that delivers a pressurized fuel and a high-pressure transition vessel. The transition vessel comprises a first inlet connected to an outlet of the solid pump so that all of the fuel from the solid pump passes through the transition vessel, a second inlet for connection to a conveyance gas line, and an outlet through which the fuel is transported to a gasifier. The transition vessel is elongated in the direction of a flow so that a conveyance gas introduced through said conveyance gas line plus the pressure difference carries the fuel to the gasifier.

    摘要： A system for use in a gasification system comprises an increasing pitch screw feeder and a high-pressure vessel disposed about said increasing pitch screw feeder. The high-pressure vessel comprises an inlet for connection to an outlet of a solid pump and a conveyance gas line and an outlet through which solid fuel delivered from the solid pump is transported to a gasifier. The outlet is downstream of the solid pump and the conveyance gas line.

    摘要： A control system for controlling a dry feed system to convey a solid fuel includes multiple sensors, a pressurizing gas controller, at least one assistant gas controller and multiple gas valves. The sensors generate multiple measurement signals signifying characteristics of the dry feed system. The pressuring gas controller calculates a feed tank pressure bias or/and a pressuring gas flow bias based on a solid flow rate and generates a first control signal based on the pressure bias or/and the pressurizing gas flow bias. The assistant gas controller calculates an assistant gas bias based on a solid loading ratio and generates a second control signal based on the assistant gas bias. The gas valves are driven by the first or/and second control signals to regulate the solid fuel. A control method is also described.
