Title: Ryoichiro Oshima: Innovator in Gas Turbine Technology
Introduction
Ryoichiro Oshima is a prominent inventor based in Hitachi, Japan. He has made significant contributions to the field of gas turbine technology, holding a total of eight patents. His innovative approaches have advanced the efficiency and performance of gas turbine plants.
Latest Patents
One of Oshima's latest patents is a method of starting a gas turbine plant. This method involves a combustor with a primary and secondary combustion chamber, a compressor for supplying compressed combustion air, and a gas turbine that drives a load such as an electric power generator. The unique aspect of this method is that during acceleration to rated speed or when the load is below a normal range, fuel is supplied only to the primary fuel nozzle. In other operational ranges, fuel is supplied to both nozzles, with a controlled air bleed to optimize performance.
Another notable patent is for a method of cooling a gas turbine blade and the apparatus for it. This innovation extracts high-pressure air from the compressor and introduces it into a water spraying chamber. Water is injected into this air to create a cooled coolant, which is then fed into the coolant passageways of the moving blade. This process enhances the cooling effect and helps maintain optimal temperatures during operation.
