Instantaneous Dosing of Slurry

During the time necessary to achieve exact thermal equilibrium in the calorimeter (approximately 1 h), which is the prerequisite for the start of a strictly isothermal measurement, a thermally instable substance in the chamber of the rotary dosing unit is changed to an unknown degree. A thermally instable substance must therefore be brought to the temperature of the reaction in as short a time as possible and then dosed as quickly as possible. It is advisable to dose thermally instable solids in the form of slurry using a dosing rmit described as follows. 

A longish chamber is installed in the vertical direction above the dosage Met of the measuring kettle in the calorimeter. It is surrounded by an electric heating jacket. The end of the chamber above the inlet is conically formed and closed by a 

The slurry is brought very quickly to the reaction temperature by the controlled heating jacket 

The slurry is dosed quasi-instantly without complications after the ball valve is opened
