Isothermal Flow Calorimeter TKR

2 Device for Continuous Reaction 2.2.1 Isothermal Flow Calorimeter TKR 

Using a conventional stirrer, the flow takes place continuously but weakly pulsating as a result of the following causes  

For a flooded flow measuring kettle a circular pendulum mixer is recommcaided for use instead of a conventional stirrer (Sect. 2.5, Fig. 2.39). 

The heat kF)2-AT2 flows from the measuring kettle into the intermediate thermostat owing to the temperature difference AT2, and the heat (k F)i ATi flows from the intermediate thermostat to the base thermostat owing to the temperature difference ATi. qui is the rate of physicochemical heat release by mixing, and following the balance of heat powers in equilibrium of control the following conditimis apply  

The heat-transfer coefficient (k F)i and the stirring power psti of the intermediate thermostat are not influenced by the reaction within the measiuing kettle they are to a certain extent apparatus constants. ATi remains constant because pi changes, regulated by a control procedure, opposite and equal to the change in the heat flow (k F)2 AT2 from the measuring kettle into the intermediate thermostat.
