Title: Yohei Kitamura: Innovator in Blast Furnace Technology

Introduction

Yohei Kitamura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of blast furnace operation, holding a total of 3 patents. His innovative methods aim to enhance the efficiency and effectiveness of blast furnace operations.

Latest Patents

One of Kitamura's latest patents is a blast furnace operation method designed to start up smoothly and maintain operations after suspending air blowing. This method involves removing residual coke that remains inside the furnace during the suspension of air blowing, which can obstruct the discharge of solidified matter. The process includes suspending air blowing when the height of the raw material-filled layer above the tuyere is reduced and resuming air blowing afterward. Additionally, oxygen or a combustible gas is introduced through a burner inserted into a taphole to combust the remaining coke, thereby reducing the volume of residues inside the furnace.

Another notable patent is a method of heating up the furnace bottom, which includes the use of a burner lance. This method involves opening a burner lance insertion hole in the tap hole, installing the burner lance, and filling the gap with refractory material. Gas is then blown into the furnace from the burner lance to heat the furnace bottom effectively.
