Patent number: 9985557Abstract: A method of operation of a thermal power plant having an air separation system with a plurality of air storage unit (ASU) compressors and a liquid oxygen/liquid air (LOX/LA) storage facility for oxyfuel firing of fossil fuel and a power plant having a control system to perform the same are described. The method is characterized by the step of controlling the net power output of the plant in response to short term variations in grid demanded net plant output by dynamically adjusting the works power of the ASU compressors preferably in conjunction with co-ordinated changes in firing demand. The method is in particular a method to produce an improved primary and secondary response to transient changes in grid demand and to provide accurate response to load dispatch ramps.Type: GrantFiled: October 28, 2011Date of Patent: May 29, 2018Assignee: DOOSAN BABCOCK LIMITEDInventors: Konrad Jerzy Kuczynski, David James Adams

Patent number: 8196510Abstract: A method for producing a flexographic plate that includes a base layer and a layer of a photosensitive material fixed on the base layer. An image is produced on the photosensitive layer by selective reticulation. Areas to be reticulated are exposed to amplitude-modulated laser light with a wavelength ranging from 390 to 410 nm, which scans the surface of the photosensitive layer. The non-reticulated areas are then removed.Type: GrantFiled: January 8, 2003Date of Patent: June 12, 2012Inventors: Jerzy Kuczynski, Gérard Rich
