Method for heating up or keeping warm the flow paths of a process plant

摘要

The invention relates to a method for heating up or keeping warm the flow paths of a process plant, wherein a stream of fluid provided for heating up or keeping warm the flow paths is guided in a circuit which comprises a heating device (8) for warming up the stream of fluid. According to the invention, to equalize the pressure loss occurring in the circuit, the stream of fluid is supplied as a suction medium to a jet pump (5) arranged in the circuit and is exposed there to a pumping medium supplied at a higher pressure.
