Compact heat exchangers for sea thermal power plants

Heat exchangers for use with ammonia and sea water were developed. While it is obvious that the heat exchangers should have high heat transfer coefficients, the basic objective is to get the greatest amount of thermal units transferred from sea water to boiling ammonia at the lowest cost for a given mean temperature difference. A design study directed toward heat exchangers constructed of flat plates with various possible constructions for the ammonia passages and the water passages is presented.
