In incineration of waste, persistent harmful chemicals such as dioxins and PCBs are sometimes unintentionally produced because of uncontrolled combustion. In order to minimize these chemicals, waste melting is now being used because its high temperature condition (about 1300℃) thoroughly decomposes these substances. The waste melting furnace requires a combustion control based on the condition of melting waste. However, it has been almost impossible to know the melting waste volume in a waste melting furnace because of disturbances due to high temperature flame and flying ash etc. We developed a melting waste height sensor, based on a laser-radar system. So that the melting waste volume has become easily determined and a good melting control was identified in a pyrolysis melting furnace.
