ABSTRACT:
The heat exchange mantle of a reaction vessel is connected with a circulating pump and a chamber provided with an electrical heating coil to form a heat exchange circulation system. To this main circulation system, a cooling circulation system comprising a circulating pump and a heat exchanger is connected by way of a continuously operable valve. The temperature of the medium circulating in the main circulation system can be very effectively and rapidly influenced by dosed addition of cooled circulation medium from the cooling circulation system into the main circulation system as well as by heating with the electrical heating coil. In the cooling circulation system, in the reaction vessel and in its mantle, temperature sensors are arranged which are linked to a control computer. The computer controls the electrical heating coil and the valve in such a manner that the temperature in the reaction vessel or in its mantle, respectively, has a desired distribution prescribed by the operational mode. Furthermore, the computer controls a recorder which records the heat flow from the reaction vessel.
