Abstract
Heat is generated by combustion of coal or like carbonaceous fuel reactant dissolved in molten salt. The generated heat is transferred to steam by an alternating sequence of direct contact heat exchanges of the salt and steam with a common heat transfer medium.
Claims4
Heat exchange apparatus for direct contact heat exchanging relatively immiscible different density liquids, said apparatus comprising a chamber, first liquid inlet means injecting a first liquid into said chamber in highly dispersed, high shear relation into a second liquid in the chamber for coalescence beyond said second liquid, a second liquid inlet means injecting a second liquid into said chamber and into said coalesced first liquid in highly dispersed high shear relation for coalescence beyond said first liquid, and, first and second liquid outlet means from said chamber opposite their respective liquid inlet means for recovery there of coalesced first and second liquid respectively passed differentially in direct contact with each other in oppositely dispersed and coalesced phase relation through the chamber.
Heat exchange apparatus for direct contact heat exchanging relatively immiscible different density liquids, said apparatus comprising a chamber, liquid inlet means to said chamber for each liquid, a liquid outlet means from said chamber for each liquid adjacent the inlet means for the other liquid, each said inlet means acting to pass its liquid in dispersed phase relation into a continuous phase of the other liquid for passage differentially in direct contact through the chamber, said outlet means recovering liquid in continuous phase and substantially free of disperse phase liquid, and jacketing means surrounding said chamber defining an insulating passage for conducting the cooler of said liquids to said chamber for heat exchange with the warmer of said liquids.
