Patent number: 7797921Abstract: A control apparatus of an extracted air booster system of an integrated gasification combined cycle power plant can additionally serve a sufficient pressure control function and a sufficient antisurge control function. For example, when an inlet guide vane is fully closed or has a small opening degree equal to or smaller than a predetermined opening degree, a second control section of the control apparatus performs pressure control based on a pressure deviation, instead of or as well as antisurge control. In the pressure control, the degree of opening of an antisurge valve is controlled so that a booster outlet pressure detection value can become equal to a set pressure value. In a case where a pressure ratio is larger than a set pressure ratio value, it is also effective that the second control section performs the antisurge control even when the inlet guide vane is fully closed.Type: GrantFiled: November 29, 2006Date of Patent: September 21, 2010Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Takashi Sonoda, Masaaki Yamasaki, Satoko Fujii, Kiyoshi Tarumizu

Patent number: 7797928Abstract: In a method for purifying exhaust gases in particular from lean-burn internal combustion engines having an exhaust-gas converter with a heat exchanger and catalysts arranged in inflow and/or outflow passages, the heat exchanger exhaust gas which flows in is heated by heat exchange with exhaust gas which flows. The incoming exhaust gas enters the inflow passages without encountering any obstacle susceptible to blockages, and flows through the inflow passages to a diversion region. Heat is fed to the exhaust gas by means of a burner. The burner is operated with fuel, air and engine exhaust gas in such a way that it supplies either an oxidizing or a reducing exhaust gas. Burner exhaust gas is admixed to the gas which emerges from the inflow passages and, together with this gas, enters the outflow passages, where nitrogen oxides are removed from it by a deNOxing catalyst present in the outflow passages.Type: GrantFiled: May 6, 2004Date of Patent: September 21, 2010Assignee: Univeritaet StuttgartInventors: Gerhard Friedrich, Grigorios Kolios, Volker Schmeisser, Ute Tuttlies, Frank Opferkuch, Gerhart Eigenberger

Patent number: 7797930Abstract: An ECU performs exhaust temperature control based on output values of multiple exhaust temperature sensors provided upstream and downstream of a particulate filter provided in an exhaust passage of an engine. The ECU calculates a change speed deviation value by subtracting change speed of outlet side exhaust temperature, which is sensed by one of the exhaust temperature sensors, from change speed of inlet side exhaust temperature, which is sensed by the other one of the exhaust temperature sensors, in an operation state in which temperature of exhaust gas flowing through the particulate filter changes rapidly. The ECU determines that the exhaust temperature sensors are mounted erroneously if the change speed deviation value deviates from a predetermined normal range.Type: GrantFiled: December 26, 2006Date of Patent: September 21, 2010Assignee: Denso CorporationInventor: Hideyuki Kusatsugu

Patent number: 7797939Abstract: A concentrating solar receiver that maximizes the amount of solar energy available for conversion to electricity that utilizes a primary reflector, a secondary reflector and a fresnel lens to both reflect and refract solar rays to a thermal cycle engine receiver which converts solar energy to mechanical energy which is in turn converted into electrical energy using an electric generator. The configuration creates focal points that protect the thermal cycle engine receiver from high temperatures and provides uniform density of solar energy within the thermal cycle engine receiver. The solar receiver is moved in response to a sun tracking sensor using a vertical and a horizontal drive motor. The thermal cycle engine and the electric generator, representing the majority of mass, are centered on the vertical support and are low to the ground.Type: GrantFiled: May 3, 2008Date of Patent: September 21, 2010Inventor: Timmy Green

Patent number: 7797943Abstract: A pilot for a scramjet provides a flame front whose arrival at the wall of the scramjet combustor is delayed thereby reducing combustor heat load. By combining in-stream injection of fuel with an interior pilot and a lean (fuel-poor) outer annulus, the bulk of combustion is confined to the scramjet combustor center. This concept, referred to as “core-burning,” further reduces combustor heat load. One such pilot is for a two dimensional scramjet effective to propel a vehicle. This pilot includes a plurality of spaced apart struts separated by ducts and a strut pilot contained within each strut. A second such pilot is for an axisymmetric scramjet engine has, in sequence and in fluid communication, an air intake, an open bore scramjet isolator and a scramjet combustor. This centerbody pilot pod includes a pilot isolator disposed between the air intake and a pilot diffuser, the pilot diffuser disposed between the pilot isolator and a pilot with the pilot disposed between the pilot diffuser and a pilot combustor.Type: GrantFiled: October 18, 2006Date of Patent: September 21, 2010Assignee: Aerojet-General CorporationInventor: Melvin J.
