Abstract: According to an embodiment, a method of operating an oxy/fuel system and an oxy/fuel system circulate a support gas in the combustion system prior to activating at least one burner, produce the combustion fluid including CO2, wherein a level of the CO2 in the combustion fluid increases as a function of time, and continue production of the combustion fluid to exceed a predetermined level of the CO2 in the combustion fluid, for a period of time, the predetermined level being sufficient to permit the CO2 to be purified by a CO2 purification unit.

Abstract: A superheater (50) in a power plant (30) that superheats steam to operation conditions exceeding an operating limit of an associated steam-producing boiler (12). The superheater (50) combusts oxygen and fuel with cooled recycled combustion gas to produce a C02-rich combustion product gas stream at a fixed temperature. The combustion gas is used as the heat transfer fluid in the superheater's heat exchanger. The C02-rich flue gas stream allows for efficient capture of substantially pure C02. The superheater (50) may be retrofitted to an existing power plant (30) as a separate component, external to the boiler. The plant may thus have its electrical power output increased, while its overall C02 emissions per nit of generated power is decreased, even when inexpensive, readily- available fossil fuels are used as the primary fuel for filing the boiler (12) and/or the superheater (30).

Abstract translation: 发电厂（30）中的过热器（50）将蒸汽过热至超过相关蒸汽生产锅炉（12）的运行极限的运行状态。 过热器（50）通过冷却的循环燃烧气体燃烧氧气和燃料，以在固定温度下产生富含CO 2的燃烧产物气流。 燃烧气体用作过热器热交换器中的传热流体。 富含CO 2的烟气流允许有效捕获基本上纯的CO 2。 过热器（50）可以作为锅炉外部的单独部件改装到现有发电厂（30）。 因此，即使使用廉价的，易于获得的化石燃料作为用于归档锅炉（12）和/或 过热器（30）。
