Vapor generator having a pair of combustion chambers

摘要

The vapor generator is provided with a vapor separator which is connected to an outlet of the partition and which has a water outlet connected to the inlet of the enclosing walls of the combustion chambers. The vapor outlet of the vapor separator connects to a superheater within the generator via platen superheaters disposed within their respective combustion chambers. The vapor separator permits the partition to always be operated with a considerable surplus of water so that no stability problems occur. A water separator is also connected to an outlet of the enclosing walls and has a vapor outlet connected with the vapor outlet from the vapor separator. Various control circuits can be used to regulate the flow of vapor from the vapor separator to the superheater. A branch conduit for the feed water is also connected in parallel with the partition to permit mixing of some of the feed water with the water separated out of the vapor separator prior to passage into the enclosing walls of the generator.
