control KS 98 application Master/slave control for an evaporator with 5 heating power stages Description For the production of nylon thread, the raw material granulate in the extruder is heated to approx. 270 °C by means of vaporized Thermex (DIPHYL®) heat transfer oil with a max. temperature deviation of 1°C. The thermal oil is evaporated, whereby the boiling point is kept constant via the steam pressure. The control equipment of the evaporator regulates the heating power for the outflow (product temperature). The working point for the necessary heating energy is determined from the difference between outflow and return flow temperatures. |
