Abstract
A stratified vapor generator (110) comprises a first heating section (H1) and a second heating section (H2). The first and second heating sections (H1, H2) are arranged so that the inlet of the second heating section (H2) is operatively associated with the outlet of the first heating section (H1). A moisture separator (126) having a vapor outlet (164) and a liquid outlet (144) is operatively associated with the outlet (124) of the second heating section (H2). A cooling section (C1) is operatively associated with the liquid outlet (144) of the moisture separator (126) and includes an outlet that is operatively associated with the inlet of the second heating section (H2).
Claims20
A stratified vapor generator, comprising:
- a first heating section having an inlet and an outlet;
- a second heating section having an inlet and an outlet, the inlet of said second heating section being operatively associated with the outlet of said first heating section;
- a separator operatively associated with the outlet of said second heating section, said separator having a vapor outlet and a liquid outlet;
- and
- a cooling section having an inlet and an outlet, the inlet of said cooling section being operatively associated with the liquid outlet of said separator, the outlet of said cooling section being operatively associated with the inlet of said second heating section.
A stratified vapor generator, comprising:
- first heating means for heating a mixed fluid;
- second heating means operatively associated with said first heating means for receiving heated mixed fluid from said first heating means and additionally heating the heated mixed fluid;
- separating means operatively associated with said second heating means for separating a liquid component from additionally heated mixed fluid from said second heating means;
- and
- cooling means operatively associated with said separating means and said second heating means for cooling the liquid component from said separating means and for directing a cooled liquid component into said second heating means, wherein the cooled liquid component mixes with a portion of the mixed fluid to be heated in said second heating means.
A method for vaporizing a mixed fluid stream, comprising:
- heating the mixed fluid stream to produce a heated mixture having a vapor component and a liquid component;
- separating the liquid component from the vapor component;
- cooling the liquid component to produce a cooled liquid component;
- and
- mixing the cooled liquid component with a portion of the mixed fluid stream being heated.
A method for vaporizing a mixed fluid stream, comprising:
- heating a mixed fluid in a heat exchanger to produce a vapor component and a liquid component;
- separating the liquid component from the vapor component;
- cooling the liquid component to produce a cooled liquid component;
- and
- mixing, in an intermediate section of the heat exchanger, the cooled liquid component with a portion of the mixed fluid being heated in the heat exchanger.
