摘要： A continuous slag processing system includes a rotating parallel disc pump, coupled to a motor and a brake. The rotating parallel disc pump includes opposing discs coupled to a shaft, an outlet configured to continuously receive a fluid at a first pressure, and an inlet configured to continuously discharge the fluid at a second pressure less than the first pressure. The rotating parallel disc pump is configurable in a reverse-acting pump mode and a letdown turbine mode. The motor is configured to drive the opposing discs about the shaft and against a flow of the fluid to control a difference between the first pressure and the second pressure in the reverse-acting pump mode. The brake is configured to resist rotation of the opposing discs about the shaft to control the difference between the first pressure and the second pressure in the letdown turbine mode.

摘要： A system includes a first pump having a first outlet and a first inlet, and a controller. The first pump is configured to continuously receive a flow of a slurry into the first outlet at a first pressure and to continuously discharge the flow of the slurry from the first inlet at a second pressure less than the first pressure. The controller is configured to control a first speed of the first pump against the flow of the slurry based at least in part on the first pressure, wherein the first speed of the first pump is configured to resist a backflow of the slurry from the first outlet to the first inlet.

摘要： The present application provides a back mixing device for use with a pneumatically conveyed flow of solids having a varying flow rate. The back mixing device may include a nozzle, a chamber in communication with the nozzle, and an exit. The chamber may include an expanded area leading to a restriction such that the chamber creates a recirculation pattern in the flow of solids so as to smooth the varying flow rate though the back mixing device.

摘要： Methods and systems for generating power using syngas created using biomass gasification are provided. Exemplary power generation systems include a biomass dryer for receiving biomass, a biomass conversion reactor (either a biomass gasifier or a steam-biomass reformer) for receiving the dried biomass and generating syngas therefrom, and an external combustor for combusting the syngas and heating a working fluid to drive a turbine connected to an electrical generator. The external combustor includes a heat exchanger element for transferring heat from combustion of the syngas into the working fluid, while maintaining the working fluid isolated from the syngas and from syngas combustion products.
