Title: Tetsuo Akiyama: Innovator in Combustion Technology
Introduction
Tetsuo Akiyama is a notable inventor based in Nishinomiya, Japan. He has made significant contributions to the field of combustion technology, holding three patents that showcase his innovative approach to enhancing heat treatment processes.
Latest Patents
One of Akiyama's latest patents is a burner designed for generating soot and a furnace that utilizes this soot for the annealing of cold-rolled stainless steel strips. This invention improves the heat absorption efficiency of the stainless steel strip in the annealing furnace, thereby enhancing its heat treatment capability. The soot generating burner operates by forming a flame through the injection of a premixed gas at a low air ratio of fuel gas and pure oxygen or high oxygen-enriched air from the nozzle opening. An air injection port is strategically placed on the outer circumference of the nozzle opening to guide the flame, creating an air curtain that directs the flame efficiently to the surface of the stainless steel strip. This design prevents soot from depositing near the nozzle opening.
Another significant patent by Akiyama is a combustion burner assembly that features a pressure equalizing control device for both combustion air and gaseous fuel. This assembly includes an inner barrel and a combustion air preheating passage arranged around a gaseous fuel supply tube. The design incorporates an annular space that communicates with the preheating passage through perforations in the inner barrel, along with an exhaust passage equipped with an exhaust gas sucking device.
