Measurements of Online Calorimeter Sensor

The run of a reaction is simulated to ensure the functionality of the online calorimeter. To that end the measuring kettle is 

An induced change in temperature in the thermostat simulates the temperature fluctuations within the technical tank reactor the working heater in the measuring kettle simulates the thermal reaction power within the tank reactor. 

The heater works initially at a constant rate of heat release q while the temperature T4 of the thermostat (virtual tank reactor) fluctuates (Fig. 5.23). 

The illusttation shows the conformity of the actual rate of heat release to the estimated one. The estimated line appears with a time lag of approximately 3 min due to the chosen finite estimation time of the Kalman-Bucy filter. 

To measure the thermal reaction power 7 of a real reaction, the online calorimeter is placed in the circulation of an ideally mixed batch reactor with 15 L volume. In the batch reactor is installed an electric heater of the same design as described in Sect. 2.1.1.
