EVAPORATION CHAMBER, INTERMEDIATE CHAMBER, AND METHOD

摘要

An evaporation chamber comprises a trough and an intermediate chamber disposed above the trough. The bottom of the intermediate chamber includes a liquid outlet through which liquid flows from the intermediate chamber into the trough. The intermediate chamber comprises a level valve, which allows a flow of liquid to follow from a liquid connection into the intermediate chamber so that the liquid level in the intermediate chamber is between a minimum level and a maximum level. The intermediate chamber has a liquid connection, a level valve, and a compensation connection. The liquid connection supplies a liquid. The level valve, allows a flow of liquid to follow from the liquid connection into the intermediate chamber so that the liquid level in the intermediate chamber is between a minimum level and a maximum level. The compensation connection is pneumatically connected to the gas space around the float.
