Definitions

  • This invention relates to combustion systems for industrial processes, including but not limited to electric power generation. More particularly, the invention relates to a high pressure oxy-fuel system, and the delivery of thermal energy from condensation from the flue gas of the high pressure oxy-fuel system to an organic Rankine cycle system.
  • direct thermal energy from the combustion in the system of the invention can be provided to a Rankine cycle or a wide variety of other systems.
  • Oxy-fuel systems are advantageous in that they provide relatively simple solutions which are applicable to new systems or the retrofit of existing systems.
  • Such systems when operated at ambient pressure suffer from disadvantages of inefficiency, as well as the higher costs arising from the need for an air separation unit for provision of the oxygen, and the costs of the carbon dioxide product recovery train.
  • Oxy-fuel systems operate at significantly higher temperatures than air- fired systems, and thus require temperature control.
  • temperature moderation There are various known methods of temperature moderation, including staging, the use of fluid beds, or the recirculation of a portion of the flue gas back to the combustor.
  • the proposed system included the variation in the conventional configurations of feedwater heaters, by removing some of them and instead using heat from condensed moisture in the flue gas.
  • conventional feedwater heater arrangements are highly developed and efficient, and any changes in those result in the need to adjust various other aspects of the system, including to address the effects of altering the regenerative extraction from the turbine; problems in making such adjustments present a significant disadvantage of the proposed system.
  • One advantage of high pressure operation is that it changes the temperature condition at which the gas to liquid phase change occurs for the flue gas, which thus allows for water vapour in the flue gas to be condensed at much higher temperatures than in air-fired systems.
  • moisture in the flue gas condenses in the range of 150°C to 200°C at 80 bar, as compared with 50°C to 55°C in ambient pressure oxy-fuel systems. It has now been found that this, and other advantages, makes the condensate from the flue gas of a pressurized oxy-fuel system a suitable heat source for use in various processes, including but not limited to power generation systems and similar systems, including Brayton cycles, Rankine cycles and binary fluid cycles, and it is particularly
  • flue gas condensate to provide heat to organic Rankine cycles. It has further been found advantageous to use the direct heat of the combustor of the system and the method of the invention to provide a direct heat energy source for various secondary systems, including but not limited to Brayton cycles, Rankine cycles and binary fluid cycles. Further, it has been found to be particularly advantageous to provide the heat of the condensate as a bottoming cycle to an organic Rankine cycle system, and to provide the direct heat of the combustion within a secondary Rankine cycle system, without making any modification to the conventional feedwater heater arrangements.
