  • DIRECT REDUCTION SHAFT FURNACE WITH PROBE FOR MEASURING INTERIOR GAS ANALYSIS
    Publication number: 20210396469
    Abstract: A direct reduction shaft furnace having at least one probe disposed vertically within the reduction zone thereof. The probe preferably extends from the top to the bottom of the reduction zone. The probe allows for gas sampling along the length thereof and transmittal of the gas to at least one type of gas analysis device. The probe may also allow for the measurement of the temperature and pressure of the gas sample as it is taken.

  • Method and apparatus for determining the health and remaining service life of austenitic steel reformer tubes and the like
    Patent number: 10060882
    Abstract: Testing methods and apparatus for testing the health of steel tubes used in reformers and other tubes and pipes used in other high temperature applications are provided. The method includes the steps of transmitting two sinusoidal electromagnetic signals, each having a different frequency F1 and F2, into the reformer tube, receiving a response signal, and analyzing the received response signal's intermodulation frequencies to determine the state of the steel reformer tube.
