Title: Tsugutoshi Yamada and Marine Exhaust-Heat Recovery

Introduction

Tsugutoshi Yamada is an inventor associated with Kashiwa, Japan. His recorded patent concerns recovering heat from the exhaust gases of marine prime movers, turning otherwise wasted energy into useful steam.

Latest Patents

Yamada is credited with 1 patent: “Apparatus for Recovering Heat from Exhaust Gases of Marine Prime Movers.” The invention describes an exhaust-gas economizer that transfers heat from engine exhaust to pressurized feed water. A pressure regulator supplies water at high and low pressures to separate steam-generating sections. The high-pressure section produces steam for driving a steam turbine, while the low-pressure section generates steam for other uses. A separator removes saturated water from the low-pressure steam, and a preheater mixes that water with incoming feed water to warm it before it enters the economizer.

Career Highlights

Yamada’s listed work is associated with Mitsubishi Jukogyo Kabushiki Kaisha, commonly known in English as Mitsubishi Heavy Industries. The patent reflects an engineering approach focused on improving the use of exhaust heat in marine power systems.

Collaborations

Kiyoshi Nagashima is identified as Yamada’s coworker. The available information does not specify the nature of their collaboration on the patent.

Conclusion

Tsugutoshi Yamada’s recorded invention addresses marine energy efficiency by recovering engine exhaust heat to produce steam for turbine operation and other onboard uses.
