1.1.4 PFU 780..D: High
temperature equipment
The flame is controlled indirectly on
the basis of the temperature. During
the start-up process, as long as the
wall temperature is below auto igni-
tion temperature the flame must be
controlled by conventional meth-
ods. When the working temperature
has exceeded 750°C, the safety
temperature monitor (STW) takes
over the indirect flame control.
