Latest Patents

Yoshiko Harada holds a patent for a method of operating heavy oil-burning gas turbines. This method involves using a fuel that incorporates various high-melting point compounds as corrosion inhibitors. The goal is to prevent corrosion during turbine operation. The patent specifies that the weight ratio of the effective metallic component (M) of the inhibitor to the corrosive component (V) of the fuel should be maintained within the range of M/V=2-5 during the initial operation period. Subsequently, the addition of the inhibitor is gradually reduced over a predetermined cycle of operation, which lasts from one to six weeks, until the final amount is reduced to one to three tenths of the initial addition.
