Abstract: A system and method generates electricity and co-produces a hydrogen flow from coal. The electricity is generated by a turbine with a topping combustor and a solid oxide fuel cell ("SOFC") reacting syngas. The syngas is produced in a coal gasifier with a portion of the compressed air from the turbine, coal, and steam. Prior to the syngas being delivered to the topping combustor and the SOFC, it is cleaned and a portion of the hydrogen in the syngas is removed to form the hydrogen flow. Additionally, a vitiated air flow from the SOFC is directed to the topping combustor and another portion of the compressed air from the turbine directed to the SOFC after it is heated with the turbine exhaust. An aspect of the invention varies the amount of electricity generated and the volume of hydrogen co-produced based upon the demand of electricity and/or the demand of said hydrogen.

Abstract translation: 一种系统和方法产生电力并共同产生来自煤的氢气流。 电力由具有顶部燃烧器和固体氧化物燃料电池（“SOFC”）的汽轮机产生，使合成气反应。 合成气在煤气化炉中生产，其中一部分来自涡轮，煤和蒸汽的压缩空气。 在将合成气输送到顶部燃烧器和SOFC之前，将其清洗并除去合成气中的一部分氢气以形成氢气流。 此外，来自SOFC的破裂空气流被引导到顶部燃烧器，并且在与涡轮排气加热之后，来自涡轮机的另一部分压缩空气被引导到SOFC。 本发明的一个方面根据电力的需求和/或所述氢的需求来改变产生的电量和共同生产的氢的体积。
