Abstract
In a steam generating apparatus comprising a shell containing feed water introduced thereinto, and heating pipes submerged in the feed water contained in the shell for permitting a heating fluid of high temperature to flow therethrough, indirect heat exchange being effected between the heating fluid and the feed water in the shell through the heating pipes so as to evaporate the feed water, spray means for supplying condensate in atomized particles to the shell and means for separating moisture from the generated steam are mounted in a space above the feed water level within the shell. The spray means has mounted therein resilient means for changing the area of openings for spraying the condensate according to the pressure of the condensate supplied to the spray means, and arrangement is such that the atomized particles of the condensate delivered into the shell through the spray means are brought into contact with the steam generated in the shell and heated thereby to a saturation temperature corresponding to the internal pressure of the shell.
