Title: Ryosuke Shimizu: Innovator in Heat Transfer Technologies
Introduction
Ryosuke Shimizu is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of heat transfer technologies, holding a total of 2 patents. His work focuses on enhancing the efficiency of reformers and tubular furnaces, which are crucial in various industrial applications.
Latest Patents
One of Shimizu's latest patents is a "Method of heat transfer in reformer." This invention involves producing a reformed gas composed mainly of hydrogen and carbon monoxide for use in fuel cells. The method utilizes a multi-tubular reformer equipped with bayonet type double-wall catalyst tubes. Hydrocarbon gas, such as natural gas, and steam are fed into the reformer. Porous media made of ceramic material are strategically arranged to envelop the leading ends of the catalyst tubes. This design enhances heat transfer from the flue gas to the catalyst tubes, preventing uneven heat distribution and allowing for stable operation of the reformer.
Another significant patent is the "Tubular furnace and method of controlling combustion thereof." This invention addresses the challenges of coking and burning in heating tubes. It employs a fluid that is heated while preventing corrosion at low temperatures due to sulfur content in the fuel. The tubular furnace achieves high efficiency by dividing the coil path into multiple zones, each with an independent regenerative-heating-type alternate combustion system. This allows for precise control of combustion and the creation of a desired heat flux pattern.
