  • Method and apparatus for monitoring atmosphere in furnaces
    Patent number: 4966348
    Abstract: A method and apparatus for operating a rotary retort heat treating furnace involves incorporating an outlet for withdrawing furnace atmosphere from the retort above the axis of rotation and conveying the withdrawn gas remotely form measurement at the temperature conditions where the heat treatment process occurs.
