Latest Patents

One of Takaba's latest patents is a gas turbine control method and apparatus. This invention aims to optimize the fuel/air mixture during decreasing load conditions in large capacity gas turbine engine systems used for electric power generation. The system is designed to maintain a relatively constant rotational speed of the turbine, which drives an electric generator unit. As electrical power demands fluctuate throughout the day, the control of the fuel/air mixture is adjusted to return the turbine exhaust temperature to a desired rated temperature. During normal load conditions, the compressor inlet guide vanes remain in a constant open position. However, when the load decreases and the temperature drops below a predetermined level, the system switches to an inlet guide vane control mode. This mode allows for more precise control of the inlet guide vanes, ensuring improved fuel/air mixture and enhanced efficiency while minimizing NOx emissions.

Another notable patent is a control apparatus for a gas turbine combustor. This invention facilitates stable combustion with limited NOx emissions by controlling the fuel flow rate based on turbine output and the flow rate of intake air mixed with the fuel. The apparatus includes means for detecting the temperature and humidity of the intake air, determining a stable combustion limit line, and correcting the intake air flow rate to maintain stable combustion.
