    • Preferred embodiments provide a system and method of generating steam comprising providing a continuous supply of coal, combusting the coal in a primary processing chamber in the presence of oxygen and water to provide a first product gas stream, recovering heat from the first product gas stream in a first heat recovery steam generator (HRSG) to produce a first steam output, processing the first product gas stream in a secondary processing chamber in the presence of oxygen and water to provide a second product gas stream substantially free of inorganic, organic and particulate contaminants, recovering heat from the second product gas stream in a second heat recovery steam generator (HRSG) to produce a second steam output, and combining the first steam output and the second steam output. In preferred embodiments, the combined steam output is used to drive a steam turbine. In certain preferred embodiments, the steam turbine is operatively coupled to an electric generator to produce electricity. In preferred embodiments, the system and method further comprises at least one of reducing the temperature of the second product gas stream, treating the second product gas stream by wet scrubbing, separating sulfur from the second product gas stream and collecting the sulfur with a baghouse, using a carbon dioxide recovery system, and discharging a treated gas stream substantially free of contaminants.
    • 优选的实施方案提供产生蒸汽的系统和方法,包括提供连续的煤供应,在氧和水的存在下在初级处理室中燃烧煤以提供第一产物气流,从第一产物气流中回收热量 第一热回收蒸汽发生器(HRSG)以产生第一蒸汽输出,在氧和水的存在下在第二处理室中处理第一产物气流以提供基本上不含无机,有机和微粒污染物的第二产物气流 在第二热回收蒸汽发生器(HRSG)中从第二产物气流回收热量以产生第二蒸汽输出,以及组合第一蒸汽输出和第二蒸汽输出。 在优选实施例中,组合的蒸汽输出用于驱动蒸汽轮机。 在某些优选实施例中,蒸汽轮机可操作地耦合到发电机以产生电力。 在优选的实施方案中,该系统和方法还包括降低第二产物气流的温度,通过湿式洗涤处理第二产物气流,从第二产物气流中分离硫并用袋式室收集硫中的至少一种, 使用二氧化碳回收系统,并且排出基本上没有污染物的经处理的气流。
