Title: Ryoji Muraki: Innovator in Fuel Combustion Control Systems

Introduction

Ryoji Muraki is a notable inventor based in Nishinomiya, Japan, recognized for his contributions to fuel combustion control systems. With a total of five patents to his name, Muraki has made significant advancements in the field of energy efficiency and environmental protection.

Latest Patents

One of Muraki's latest patents is a fuel combustion control system. This system calculates the estimated fuel flow rate by reading initial data that relates the opening degree of a fuel control valve to the fuel flow rate. A compensation coefficient is then determined based on this estimated fuel flow rate, allowing for precise control of the actual fuel flow rate. Additionally, the system calculates the estimated excess air ratio by analyzing second data that represents the relationship between the opening rate of an air control damper and the air flow rate. The actual fuel and air flow rates are then controlled according to a predetermined relationship between the estimated and desired excess air ratios. Another significant patent is an input control method and means for nitrogen oxide removal. This innovation focuses on removing nitrogen oxide from flue gas produced by heating units. The removal process involves injecting a nitrogen oxide removing agent in an amount determined by the nitrogen oxide concentration in the flue gas. This concentration is detected through calculations based on factors such as the fuel supply rate and oxygen concentration, as well as direct measurements for a fail-safe system.
