4.2.2 Set-up the interface temperature
The interface temperature can be set to either the
“Auto” or “Manual” mode. In the “Auto” mode, the
interface temperature is automatically controlled based upon the pyrolyzer furnace temperature; on
the other hand, in the
“Manual” mode, it is always controlled at the selected temperature. These
modes are entered - see E-4 of Fig. 4.3. Normally, the
“Auto” mode is used. If the “Manual” mode is
selected, the interface temperature is controlled at a constant temperature - see E-3 of Fig. 4.3. In the
“Auto” mode, the temperature is maintained 100°C above the pyrolyzer furnace temperature; the
interface temperature set in E-3 is the upper limit temperature. For example, the relationship between
the Pyrolyzer furnace and interface temperatures is shown in Fig. 4.6. In this example, the
“Auto”
mode is selected using E-4 and the upper temperature is set to 300°C using E-3; the Pyrolyzer
furnace is heated from 50°C to 500°C. The interface initial temperature is automatically set to 150°C,
100°C above the Pyrolyzer furnace temperature, and the temperature increases to 300°C - the upper
temperature limit (E-3).
