Patent number: 9481839Abstract: A hot oxygen nozzle and uses thereof in a gasifier, the hot oxygen nozzle comprising an outer-ring spout, a middle-ring spout, an inner-ring spout, and a central spout all sequentially and coaxially disposed, and a cooling system; the gasifier is an entrained-flow gasifier provided with one or more nozzles on a certain plane or a plurality of planes at the top or on the periphery of the gasifier body. The nozzle has a simple structure and is easy to make and maintain. A fuel gas passage is disposed inside the nozzle. Oxygen can be heated by a combustion of fuel gas; and high-temperature and high-speed oxygen can directly ignite carbonaceous materials such as coal-water slurry and coke-oven gas. The present invention can be applied in a gasifier and then in the final process of synthesis gas preparation.Type: GrantFiled: November 26, 2013Date of Patent: November 1, 2016Assignees: PRAXAIR TECHNOLOGY, INC., EAST CHINA UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Qinghua Guo, Tao Wang, Zhenghua Dai, Guangsuo Yu, Xin Gong, Fuchen Wang, Haifeng Liu, Yifei Wang, William J.

Patent number: 5722801Abstract: Particulate material is conveyed in a dense phase in either a batch mode of conveyance or a continuous mode. In either mode, during the conveyance cycle, the flow rate of compressed gas to the transporter vessel is adjusted to control material conveyance. During start-up the flow rate is decreased to allow material to build in the vessel, then the rate is increased to a normal conveyance value. At the end of the cycle, the flow rate is again decreased to avoid surges and high velocity flow. During the normal conveyance cycle, the flow rate is decreased if the material level in the vessel falls below a minimum value and increased if it rises above a maximum value. The flow rate is adjusted by opening and closing the throat in a venturi tube in an adjustable valve in the gas flow line connected to the vessel.Type: GrantFiled: December 21, 1995Date of Patent: March 3, 1998Assignee: The Young Industries, Inc.Inventor: William J. Mahoney, Jr.

Patent number: 4632565Abstract: A single-pass blending apparatus for blending particulate solids including a blending bin having a bin wall, an upper bin end, a lower bin end, a first bin opening passing through the bin wall, and a second bin opening passing through the bin wall and spaced vertically and horizontally from the first bin opening. The bin wall defines a bin chamber. A plurality of flow openings pass through the lower bin end. A blending chamber is positioned beneath the bin chamber and communicates with the bin chamber through the flow openings. A first external blending tube is positioned outside of the blending bin and has an upper tube end communicating with the first bin opening and a lower tube end external of the bin chamber and communicating with the blending chamber. A second external blending tube is positioned outside of the blending bin and has an upper tube end communicating with the second bin opening and a lower tube end external of the bin chamber and communicating with the blending chamber.Type: GrantFiled: October 29, 1984Date of Patent: December 30, 1986Assignee: The Young Industries, Inc.Inventor: William J.
