    • The invention provides systems and methods for electric power production and integrated combustion and emissions control. The invention may include an engine capable of receiving air and fuel, and producing power and an engine exhaust gas. The invention may also include a first reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of more than one, thereby generating a first product. The combustion may reduce nitrogen containing species. The invention may also include a second reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of less than one, thereby generating a second product. The combustion may reduce or minimize NOx. The invention may also include a mixing zone configured to receive the first product and second product, and mix and react the first and second products, thereby generating an exhaust with reduced NOx levels. This may occur with sufficient residence time and temperature to complete combustion and promote nitrogenous species reduction reactions. For inventions with multiple zones, fuel or air or exhaust gas may be adjusted, diverted or turned off as load is reduced to maintain flame stability for all zones that remaining operational. For inventions with engine exhaust that provides less oxidant than the burner requires, an air eductor means may be arranged between the engine and the burner that entrains needed additional oxidant and simultaneously recovers the flow energy in the turbine exhaust.
    • 本发明提供了用于电力生产和综合燃烧和排放控制的系统和方法。 本发明可以包括能够接收空气和燃料并且产生动力和发动机废气的发动机。 本发明还可以包括接收来自发动机的发动机废气的第一反应区域,其构造成燃烧具有多于一个的当量比的燃料和空气,从而产生第一产物。 燃烧可以减少含氮物种。 本发明还可以包括第二反应区,其接收来自发动机的发动机废气,其构造成燃烧具有小于1的当量比的燃料和空气,从而产生第二产物。 燃烧可以减少或最小化NOx。 本发明还可以包括配置成接收第一产品和第二产品的混合区,并且混合和反应第一和第二产品,从而产生具有降低的NOx水平的排气。 这可能发生在足够的停留时间和温度下完成燃烧并促进含氮物质还原反应。 对于具有多个区域的发明,燃料或空气或废气可能被调节,转向或关闭,因为减少了负载以维持所有保持运行的区域的火焰稳定性。 对于具有比燃烧器要求更少的氧化剂的发动机排气的发明,可以在发动机和燃烧器之间布置空气喷射装置,其夹带所需的另外的氧化剂并同时回收涡轮机排气中的流动能量。
