Notes on the reactor temperature during commissioning

During commissioning of the BEKOKAT
This condition usually occurs when the commissioning of the BEKOKAT
by mode, i.e. without compressed air.
 When the set nominal temperature in the reactor is reached, the valves open at the inlet
and condensate drain of the BEKOKAT
 In the further course, the reactor temperature can reach values> + 200 °C, because there
is no cooling by the flow of compressed air.
 The heating of the reactor takes place from the container wall to the centre of the reactor
bed. That is, during commissioning, the outer edge of the bed is first heated. After a
relatively short time a temperature of + 260 °C is reached and the heating system
switches off. At this time, the temperature at the sensor is still significantly lower, e.g. +
90 °C. Although the heating system has been turned off, the heat migrates to the centre
of the container and causes heat distribution throughout the reactor bed.
 The rise in temperatures above +200°C only occurs when heating during the
commissioning. This effect is caused by the large temperature difference between reactor
wall and reactor centre.
 If the reactor is flowed through with compressed air immediately after opening the valves,
then the heating above + 200 °C by the heat discharge by means of the compressed air
is avoided.
 In the further course, the heat exchange within the container only leads to fluctuations
between + 150 °C and + 175 °C. Values over + 200 °C are not reached.
 Thus, the valves remain permanently open in stand-by mode.
