Permissible flow temperature
1)
1) Safety limit (high limit safety cut-out).
Maximum possible flow temperature with control units of the seriesCFB 800/CFB 900= safety limit (STB) - 18 K.
Example: safety limit (STB) = 100 °C, maximum possible flow temperature = 100 – 18 = 82 °C.
Maximum possible flow temperature withCC 8000control units control units of the seriesCFB 800/CFB 900= safety limit (STB) - 12 K.
Example: safety limit (STB) = 99 °C, maximum possible flow temperature = 99 – 12= 87 °C.
