Title: An apparatus for detecting carryover particles in the interior of a furnace
Inventor: KYCHAKOFF GEORGE
IPC: F23M11/04
Filed: 1991-04-15
Granted: 1996-02-20
Abstract: An apparatus for detecting the presence of carryover particles in an upper region of a furnace, such as a smelt bed boiler, includes plural spaced apart detectors.  These detectors monitor discrete portions of the interior of the furnace for the purpose of detecting carryover particles in such monitored portions. Signals indicative of the carryover particles are processed to obtain a count of the carryover particles.  The carryover particle count may then be displayed.  For example, the signals from all of the detectors may be averaged with trends and overall changes in count rates then displayed. In addition, the counts from the individual detectors may also be displayed to assist an operator in locating the source of excessive carryover particles in the furnace. An image sensor, such as a charged coupled device (CCD) detector, may be used to provide a visual display of detected carryover particles.  The information on carryover particle count may be used in controlling parameters affecting the performance of the furnace directly, or indirectly by way of operator input.

Patent CA-2094369-C (CA)
Inventor: ROHATGI PRADEEP KUMAR
IPC: C22C49/14
Filed: 1993-04-19
Granted: 2001-04-10
Abstract: The invention provides an aluminum-base composite material. The aluminum-base material contains a uniform distribution of carbide particles and lubricating phase particles such as carbon or graphite. The carbide particles increase hardness for improved wear resistance. The lubricating phase particles provide improved wear resistance and especially improve unlubricated wear resistance under increased loads. Finally, a dispersoid of nickel aluminide intermetallic phase may also be used to provide additional hardness and wear resistance. The composite is formed by introducing carbide particles and lubricating phase such as graphite into a molten aluminum alloy to neutralize buoyancy and to form an aluminum-base mixture. Mixing the aluminum-base mixture to uniformly distribute carbide and carbon particles throughout the molten aluminum. Carbide and carbon particles counteract each other to remain uniformly distributed throughout the aluminum-base alloy despite prolonged holding or cooling times.

Abstract: A baffle system for use in a clarifier tank having a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank is formed by a plurality of individual and cooperatively-engageable baffles mounted on the peripheral tank wall. Each baffle includes a panel member that downwardly slopes from the peripheral tank wall toward the interior of the tank and the tank bottom and terminates at a lower ledge disposed in spaced relation above the tank bottom. A first lateral end of the panel member unitarily carries an end bracket securable to the peripheral wall for supporting the panel member in a cantilevered fashion. The plural baffles are disposed in end-to-end relation about the peripheral tank wall such that the second lateral end of the panel member of each baffle is secured to the end bracket of the next-adjacent baffle whereby each end bracket supports the panel members of each set of two immediately-adjacent baffles on the peripheral wall. The resulting baffle system provides a smoothly continuous, inwardly and downwardly sloping surface along which solids precipitated from the liquid-solid suspension contained in the clarifier tank are gravitationally-directed to the tank bottom.

Granted: 1999-05-11
Abstract: An oxygenated organic liquid product and a fuel gas are produced from a portion of synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, and sulfur-containing compounds in a integrated feed treatment and catalytic reaction system.  To prevent catalyst poisoning, the sulfur-containing compounds in the reactor feed are absorbed in a liquid comprising the reactor product, and the resulting sulfur-containing liquid is regenerated by stripping with untreated synthesis gas from the reactor. Stripping offgas is combined with the remaining synthesis gas to provide a fuel gas product.  A portion of the regenerated liquid is used as makeup to the absorber and the remainder is withdrawn as a liquid product.  The method is particularly useful for integration with a combined cycle coal gasification system utilizing a gas turbine for electric power generation.
