MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617074500 A) filed by National University Corporation Kagawa University on June 16, 2026, for Combustor, Combustion System, And Combustion Method.

Inventor includes Okumura Yukihiko.

The application for the patent was published on July 10, 2026, under issue no. 28/2026.

Abstract: Provided are a combustor, a combustion system, and a combustion method capable of reducing the amount of unburned fuel emitted. A combustor (AA) includes: a first combustion cylinder (10) which has one end that is closed by a bottom portion (13); a second combustion cylinder (20) which is connected to the first combustion cylinder (10) and which has an inner diameter greater than that of the first combustion cylinder (10); a first nozzle (41) which ejects first fuel from a first ejection port (16) formed in a side wall of the first combustion cylinder (10) in a direction toward the bottom portion (13) along an inner peripheral surface of the side wall; and a second nozzle (42) which ejects second fuel from a second ejection port (26) formed in a side wall of the second combustion cylinder (20) in a direction along an inner peripheral surface of the side wall. Since a swirling flow of the first fuel is reflected by the bottom portion (13), the residence time of the first fuel is increased, and a high-temperature reaction zone can be generated in a central portion of the combustion chamber. In addition, high-temperature air supply employing ultra-lean combustion in the second combustion cylinder (20) is performed. As a result, combustion of the fuel is promoted, and the amount of unburned fuel emitted can be reduced.
