一种利用压缩和加湿的热空气和燃料产生机械动力的过程，将它们混合在一起并燃烧，产生的热燃烧气体通过燃气轮机膨胀。空气首先被压缩并通过水流进行中间冷却，然后进一步压缩并直接传递到热回收单元，在热回收单元中使用来自压缩空气中间冷却步骤的水对其进行加湿。压缩的加湿空气进一步被热涡轮废气加热，并在燃烧器中与燃料结合，所产生的热燃烧气体通过燃气涡轮膨胀，以产生驱动空气压缩所需的机械动力。热涡轮机废气与压缩加湿空气流和水流逆流冷却，然后排放到大气中。通过消除空气组合加湿和加热步骤上游的通常单独的空气后冷却和饱和器单元，提高了本方法的工艺热效率并降低了设备成本。
A process for producing mechanical power utilizing compressed and humidified hot air and a fuel, which are mixed together and combusted and the resulting hot combustion gas is expanded through a gas turbine. The air is initially compressed and intercooled against a water stream, and then further compressed and passed directly to a heat recovery unit where it is humidified using the water from the compressed air intercooling step. The compressed humidified air is further heated against hot turbine exhaust gas and combined with a fuel in a combustor, and the resulting hot combustion gas is expanded through a gas turbine to produce mechanical power needed for driving the air compression. The hot turbine exhaust gas is cooled countercurrently against the compressed humidified air stream and against the water stream, and then discharged to the atmosphere. By eliminating a usual separate air aftercooling and saturator unit upstream of the air combined humidifying and heating step, process thermal efficiency for the present process is increased and equipment cost reduced.
