Title: PASSIVE FILL STATE REGULATING SYSTEM
Abstract:
The invention relates to a passive fill state regulating system comprising the following - a container (4) which receives a primary medium (P), said primary medium (P) having a liquid phase (6) and a steam phase (8) in the container (4) during operation, - a primary medium (P) supply line (10) which is connected to the container (4) and into which a regulating valve (14) is connected, and - a standpipe (18, 18') which is connected to the container (4) as communicating pipes and through which the primary medium (P) flows. A part of the standpipe (18, 18') forms the primary side of a heat exchanger (20), the secondary side of which has a secondary line (30) that receives a secondary medium (S), wherein a pilot valve (16) which acts on the regulating valve (14) is connected into the secondary line. The invention is characterized in that the heat exchanger (20) has an elongated heat exchanger surface (32) which is largely vertically aligned, and the pilot valve (16) and the regulating valve (14) can be adjusted continuously such that the flow through the supply line (10) continuously varies with the fill state of the liquid phase (6) in the container (4).
