Title: Tsutomu Kuwahara: Innovator in Plasma Melting Technology
Introduction
Tsutomu Kuwahara is a notable inventor based in Nara-ken, Japan. He has made significant contributions to the field of plasma melting technology, holding a total of 2 patents. His innovative approaches have led to advancements in the efficiency and effectiveness of melting processes.
Latest Patents
Kuwahara's latest patents include a plasma melting method and a plasma melting furnace. The plasma melting furnace features a melting chamber equipped with an anode torch and a cathode torch made of graphite, with an electric conductor positioned at the bottom. During operation, the anode torch, which has an inflow of electrons and forms an unstable plasma arc, is not utilized. Instead, the cathode torch, which has an outflow of electrons and forms a stable plasma arc, is employed for heating. This design allows for stable and continuous operation of the furnace, significantly reducing the electrode consumption rate.
Another patent focuses on an ash melting furnace arrangement and a method for supplying ash to the furnace. This invention includes a dry sorting machine that removes solids larger than a predetermined size from the ash and dries it. Additionally, a magnetic sorting machine is used to eliminate metals from the dried ash. The system also incorporates a drying air pipe that introduces high-temperature air, recovered from exhaust gases, into the dry sorting machine. This innovative approach simplifies the ash pretreatment process and reduces the required installation space.
