Patent number: 11598524Abstract: In a high-efficient clean, high-variable load rate coal-fired power generation system, through the internal thermal source SCR denitration catalytic module coupled with high temperature and low temperature storage tanks, the operating temperature of the internal thermal source SCR denitration catalytic module is controlled in a range of 300° C. to 400° C., ensuring that the SCR catalyst has high activity in full-working conditions. Moreover, the high temperature and low temperature storage tanks are coupled with the high-pressure heater group for steam turbine regenerative system, so that when the coal-fired unit needs to increase load rate, the thermal storage energy is quickly converted into output power. In addition, energy stored in the high temperature and low temperature storage tanks come from both the internal thermal source SCR denitration catalytic module and the thermal storage medium heater within the boiler, the operational flexibility and the boiler efficiency are improved.Type: GrantFiled: January 25, 2021Date of Patent: March 7, 2023Assignee: XI'AN JIAOTONG UNIVERSITYInventors: Junjie Yan, Ming Liu, Jiping Liu, Daotong Chong, Qinan Xing, Chaoyang Wang

Patent number: 11598527Abstract: A method of reducing noise from a combustor of a gas turbine engine includes the steps of establishing a maximum noise limit that may be for a particular frequency range. A primary fuel flow percentage, which may be emitted from a fuel nozzle arrangement having various groupings of simplex and duplex nozzles, is then established. An immersion depth measured between an aft rim of a swirler and a distal tip of the fuel nozzles may then be reduced thereby reducing the noise amplitude.Type: GrantFiled: June 9, 2016Date of Patent: March 7, 2023Assignee: Raytheon Technologies CorporationInventors: Justin M. Locke, Dennis Moura, Duane McCormick, Scott A. Liljenberg, Theodore Strickland, William Proscia
