Method for sliding control the temperature of chemical substances with defined a - and outlet temperatures in a heater and device for carrying out the method

摘要

The present invention relates to a method for sliding control the temperature of chemical substances with defined a - and outlet temperatures in a heater which, in a specific, defined pressure range, and is held by the heater are guided as well as a device for carrying out the process as a supplemental application for patent application 102007015619.9 with the objective of a method and a device of the same general nature to, with which it allows is an economically advantageous, safe and environmentally benign operation of the device, in particular in the case of starting processes, to obtain. The present invention achieves the object is achieved by means of a method and a device for regulating the temperature of a sliding material stream of chemical substances with defined a - and outlet temperatures in the device with a heater, wherein the chemical substance in the direction of flow of the start-up process, coming from the heater, a cooler, is cooled and heated so that a shut-off valve, is suctioned an expansion tank, flows in which the chemical substance for a volume - and pressure compensation of the side walls arrangement is introduced, in cooperation with a connection to the main line in the case of equality of the chemical substance in the inventive arrangement, the start-up process is continued.
