Patent number: 10203112Abstract: A coal fired oxy boiler power plant is disclosed in which a steam coil oxygen preheater located on an oxygen line Air Separation Unit is thermally integrated with the condensate system. Thermal energy for the steam coil oxygen preheater is provided via an extraction line connected to a steam extraction port of an intermediate pressure steam turbine. A drain line of the steam coil oxygen preheater fluidly connects the steam coil oxygen preheater to a point of the Rankine steam cycle fluidly within the condensate system.Type: GrantFiled: May 8, 2015Date of Patent: February 12, 2019Assignee: General Electric Technology GmbHInventors: Thierry Pourchot, Francois Granier, Frederic Geiger

Patent number: 10006634Abstract: A coal fired Oxy boiler power plant having a combustion system configured to burn coal using an oxygen stream to produce a flue gas stream, a CO2 capture system connected to the flue gas stream and a steam cycle with serially arranged low pressure heaters forming part of a condensate system. The combustion system includes, an Air Separation Unit for removing N2 from air to produce the oxygen stream for the boiler. The Air Separation Unit includes an Air Separation Unit heat exchanger that is thermally and fluidly connected to the condensate system so as to be fluidly parallel to at least one serial low pressure heater and fluidly parallel to at least one less that the total number of serial low pressure heaters. The Flue Gas Heat Recovery System, Flue Gas Condenser and Gas Processing unit are thermally integrated into the condensate system.Type: GrantFiled: May 8, 2015Date of Patent: June 26, 2018Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Thierry Pourchot, Francois Granier, Frederic Geiger

Patent number: 9944875Abstract: The invention relates to a lignite fired steam power plant comprising a water/steam power cycle and a lignite dryer system having a heat pump circuit configured and arranged to provide heat energy to a lignite dryer of the dryer system. The heat pump includes a dryer heat exchanger, an expansion device and an evaporator heat exchanger connected to the first outlet line so as to enable heat energy transfer from the vapour of the first outlet line to the first working fluid. A compressor is also included in the heat pump circuit. In addition the heat pump circuit is connected to the water/steam power cycle by a steam makeup line from the pressure series of steam turbines and a condensate return line.Type: GrantFiled: May 24, 2016Date of Patent: April 17, 2018Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Thomas Edel, Frederic Geiger, Thierry Pourchot, Didier Wantz
