Title: Kenzo Tsujikawa: Innovator in Coke Oven Technology
Introduction
Kenzo Tsujikawa is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of coke oven technology, holding 2 patents that focus on improving fuel control methods during the coal carbonization process.
Latest Patents
Tsujikawa's latest patents include a "Method of Controlling Fuel for a Coke Oven" and a "Method of Regulating Fuel Supply Rate for Heating a Coke Oven." The first patent describes a programmed heating method that changes the fuel supply rate during the carbonization process. This method aims to reduce the fuel supply rate from a large flow rate to a smaller flow rate, including a zero rate, when the coal center temperature is between 350°C and 700°C. The second patent outlines a method for regulating fuel supply by establishing a standard curve for ethylene or tar concentration based on operating conditions. This method measures the concentration in the coke oven gas and adjusts the fuel supply rate to minimize discrepancies between measured and standard values.
