(cabinet if fully lled with steam and all sur-
faces have reached steam temperature).
2. After steam saturation inside cabinet steam
will also ll quenching chamber
3. After reaching quenching temperature (B2)
quenching solenoid Y2 will be activated.
Depending on the frequency of temperature
raise of the quenching sensor B2 the duration
of the next steam supply is calculated.
B2 temperature with partial load
B2 temperature with full load
4. The amount of steam inside the cabinet is
directly depending on the temperature varia-
tion of quenching sensor B2.
