SOUNDBITE 3 (English): TIM ACKER, Visitor STORYLINE: When the first ray of sun appeared from the end of Lake Burley Griffin in the Australian capital Canberra, hundreds of people waited in the chill of early autumn, many of whom with a smile on their faces. Flames were roaring in the sound of gas burners as the hot air balloons, in different shapes and colors, rose up one after another, while the crowds burst into applause and cheers. Sunday is the last day of the annual Canberra Balloon Spectacular which started on March 12 this year. The event inaugurated in the 1980s has seen 25 giant balloons this year from acro

Toho Gas' "Air Ratio Visualization System" for Monitoring Combustion Conditions

Toho Gas' "Air Ratio Visualization System" for Monitoring Combustion Conditions

Toho Gas Co., Ltd. has developed the "Air Ratio Visualization System," a system to monitor the combustion condition of gas burners for industrial furnaces used in heat treatment and aluminum melting by measuring the difference between the theoretical required amount of air and the amount of air during combustion. The system can be done at low cost, employing general-purpose products such as oxygen sensors for automobile exhaust gas and EMS controllers for information transmission equipment. The system will be used to strengthen services as a solution for energy saving and efficient maintenance. The system has been narrowed down to the oxygen concentration measurement function, making it easier to use general-purpose products. However, if an automotive exhaust gas sensor is used as is, it will lose its output after about six months, so we developed our own control logic to extend its life.
