    • 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。

    • A NOx reduction burner system and process. Fuel modification and fuel rich reactor zone gases are brought together with products from a fuel lean reactor zone in a low temperature burnout and NOx reduction reactor zone. The fuel modification fuel rich reactor stabilizes combustion through recirculation of hot gases to the reactants. Nitrogenous species decay reactions in the fuel rich zone controls the production of NOx. The nitrogenous species from the fuel rich zone and the NOx from the fuel lean zone then react in the burnout zone at an optimal temperature and nitrogenous species mix where NOx is minimized. Temperature in all zones, and in particular the burnout zone, can be controlled by furnace gas entrainment, induced flue gas recirculation, forced flue gas recirculation and active cooling by radiative and/or convective heat transfer. NOx can be even further reduced by introducing ammonia, or a like amine species, into the low temperature burnout zone. By balancing combustion and emissions control reactions over several zones, low emissions can be achieved under good flame stability, turndown, heat transfer and noise characteristics.
    • 一种NOx还原燃烧器系统及工艺。 燃料改性和富含燃料的反应器区气体与来自低温焚烧和NOx还原反应器区域中的贫燃料反应器区域的产物一起进入。 燃料改性富燃料反应堆通过将热气体再循环到反应物来稳定燃烧。 富含燃料区的含氮物质衰变反应控制了NOx的产生。 来自燃料富集区的含氮物质和来自燃料贫化区的NOx然后在最佳温度的燃尽区和NOx最小化的含氮物质混合物中反应。 所有区域,特别是燃烧区域的温度可以通过炉内气体夹带,诱导烟道气再循环,强制烟道气再循环以及通过辐射和/或对流热传递进行主动冷却来控制。 通过将氨或类似的胺物质引入到低温烧尽区域中,甚至可以进一步降低NOx。 通过在几个区域平衡燃烧和排放控制反应,可以在良好的火焰稳定性,调节,热传递和噪声特性下实现低排放。

    • A low NOx combustion process and burner apparatus in which a mixture of a primary fuel and air, with the air in excess of the stoichiometric requirement, is passed to a surface burner element. The mixture is distributed over the downstream side of the element where it is combusted in a primary combustion zone. Secondary fuel is mixed with surface combustion products from the primary zone and then combusted in a secondary combustion zone with a portion of excess oxygen from the surface combustion products. In certain embodiments the temperature of surface combustion products is reduced by heat transfer to the surface burner element, and in another embodiment by heat transfer to a screen or other element placed within the primary combustion zone, from which the heat is then extracted to a load, and in another embodiment by mixing the additional fuel or combustion products with cooled furnace gases. In other embodiments the placement of the secondary fuel jets is varied to achieve different combustion results.
