Patent number: 8468831Abstract: Embodiments of this invention provide a premixed pilot assembly for use with a fuel nozzle for a turbine. The level of nitrogen oxide (NOx) emitted by the pilot is reduced by mixing the fuel and air fast, at the end of the pilot nozzle, thereby avoiding significant zones of rich fuel and air mixtures. The air is mixed with the fuel through the use of openings in a first cylinder and a second cylinder, one of which carries air and one of which carries pilot fuel. The openings can be configured as necessary to obtain a desired effect on the pilot.Type: GrantFiled: July 13, 2009Date of Patent: June 25, 2013Assignee: General Electric CompanyInventors: Krishnakumar Venkataraman, Manish Kumar, Jason Thurman Stewart

Patent number: 8393555Abstract: A moistening nozzle of a paper web comprises a frame into which air and water are fed. Inside the frame there is arranged a water nozzle wherewith water is conducted to an outlet of the moistening nozzle and an air nozzle wherewith air is correspondingly conducted to the outlet. The air nozzle and the water nozzle are arranged one within the other such that the air and the water form water mist that is sprayed out from the moistening nozzle. The air nozzle is provided with a thread that brings the air in swirling motion. The air nozzle comprises a sleeve part with an opening through which air is discharged and in said opening there is arranged a piece that is an integral part of the frame of the moistening nozzle, whereby a part of the moistening nozzle frame forms an inner edge of the air gap provided by said piece and the sleeve part.Type: GrantFiled: July 6, 2006Date of Patent: March 12, 2013Assignee: Metso Automation OyInventors: Hannu Niemela, Niko Posti, Jari Almi
