Abstract

This invention sets forth a double-acting piston, which carries a floating piston, and which is reciprocated in a housing, for feeding coal to a high pressure gasifier system. The housing has a plurality of solids (for instance: coal) in-feeding ports and a single discharge port, the latter port being in communication with a high pressure gasifier system. The double-acting piston sequentially and individually communicates each of the in-feeding ports with the discharge port. The floating piston both seals off the discharge port while each in-feeding port is receiving coal or the like, to prevent undue escape of gas from the gasifier system, and translates in the housing, following a discharge of coal or the like into the discharge port, to return gas which has been admitted into the housing back into the gasifier system.

Feeder for bulk solids

Patent Nichol, Corrie Ian

A feeder for bulk solids has a rotatable bin with an open bottom and an open top and is tilted so that one side of the bin is substantially vertical. A rotating auger is located within the bin having a vertically oriented exposed helical fin. Longitudinal ribs are secured on an inner surface of the bin and spaced radially. Material is loaded into the open top of the rotating bin, tumbling the material toward the bottom of the bin causing the material to constantly contact the rotating auger. The auger then feeds the material through the open bottom of themore »« less

Solid feeder and method

Patent Hathaway, Thomas J [Belle Meade, NJ]

This invention provides a housing containing a rotatable coal bucket that is sealed at its ends in the housing with a reciprocal plunger that is sealed in the bucket at one end and has an opposite cone-shaped end that wedges up against a closed end of the bucket, and a method for feeding dry, variable size coal from an ambient atmosphere at low pressure into a high temperature, high pressure reactor between the seals for producing fuel gas substantially without losing any high pressure gas from the reactor or excessively wearing the seals. To this end, the piston biases themore »« less

System and method and apparatus for maintaining a pressure balance in a solids flow loop and for controlling the flow of solids therethrough

Patent Chiu, Jonq-Hai

A system includes a standpipe for receiving a flow of solids therethrough, the standpipe having at least one inlet configured to receive a gas for decreasing a solids-to-gas ratio of the flow, a sealpot having an inlet fluidly coupled to the standpipe and an outlet fluidly coupled to a riser, the sealpot being configured to fluidize the solids received from the standpipe and to transport the solids to the riser, and a drain device fluidly coupled to an outlet in the standpipe, the outlet being located upstream from the inlet of the sealpot. The drain device is configured to removemore »« less

Method and apparatus for semi-solid material processing

Patent Han, Qingyou [Knoxville, TN]; Jian, Xiaogang [Knoxville, TN]; Xu, Hanbing [Knoxville, TN]; ...

A method of forming a material includes the steps of: vibrating a molten material at an ultrasonic frequency while cooling the material to a semi-solid state to form non-dendritic grains therein; forming the semi-solid material into a desired shape; and cooling the material to a solid state. The method makes semi-solid castings directly from molten materials (usually a metal), produces grain size usually in the range of smaller than 50 .mu.m, and can be easily retrofitted into existing conventional forming maching.

Apparatus and method for coating bulk quantities of solid particles

Patent Zeberoff, Anthony F.; Roeder, Jeffrey F.; Van Buskirk, Peter C.

An apparatus and method is described to coat small and large quantities of solid particles using atomic layer deposition, with increased material utilization and decreased cycle times. The resulting higher coating efficiency ALD process is achieved by a controlled pressure differential acting across a rotating porous vessel that contains a plurality of solid particles. The apparatus is comprised of two coaxial cylindrical porous vessels with a means for one to rotate, and a two stage rotary feedthrough with a specialized hollowed out shaft, which enables both rotation of the vessel and reactant, purge, and product gas transport across a particlemore » bed that undergoes mixing.« less
