  • Patent number: 9453646
    Abstract: An improved combustor is disclosed in which conventional combustion is changed to “rich to quench to lean” by changing the air entry arrangement in the liner of the combustor to remove mixing holes, reduce liner cooling and admit dilution air into the combustor liner in place of mixing air. In an alternative embodiment, dilution air is admitted into the combustor liner with the help of a plurality of pipes arranged so that air comes into the liner as a swirling flow in a direction opposite to nozzle swirl, so as to thereby produce a large mixing of air with the combustion gases and a resulting quenching effect, i.e., a rapid cooling of the combustion gases by quenching air. As such, the requirement for cooling water to quench the combustion gases is significantly reduced, thereby helping turbine efficiency and reducing turbine emissions.

  • Patent number: 9455580
    Abstract: A battery system has a battery module including a number M of series-connected batteries. The battery system is further provided with a number N (1<N?M) of charge equalizers, each of which once connected to a battery, causes the battery to be charged and/or discharged to achieve charge equalization. A control device is configured to determine for each battery if it requires charge equalization based on a state of charge (SOC) of the battery, compare a number L of the batteries that require charge equalization and the number M, and based on the comparison result, cause the battery system to be shut down, or the one or more batteries that require charge equalization to be connected to corresponding charge equalizers. A selective switch module is used for connecting the one or more batteries that require charge equalization to corresponding charge equalizers, respectively.
