Latest Patents

Koji Ogata holds a patent for an "Exhaust system for steam turbine." This invention features an improved annular flow guide designed for high or intermediate turbines. The innovative flow guide reduces flow turbulence in the exhaust hood and minimizes pressure loss, thereby improving the overall efficiency of turbine plants. The design modifies the conventional vertically symmetric shape of the flow guide to a vertically asymmetric shape, allowing for a longer downstream flow guide portion compared to the upstream portion. Numerical analyses were conducted to determine the optimal flow guide occupation ratios, which were set at 0.4 for the upstream and 0.7 for the downstream, resulting in a lower total pressure loss coefficient than the reference values.
