Abstract
A heat recovery vapor trap is provided for removal of vapor condensate from a container, while preventing any appreciable escape of vapor, and for achieving beneficial heat recovery from said condensate prior to temperature degradation associated with depressurization, whereby useful heating to much higher temperature is possible. The trap is indirect acting, and is preferably mechanically actuated by a float.
Claims20
An apparatus for controlling the liquid level in a container containing saturated vapor and liquid, and for recovering heat from the liquid discharged from said container by said level control apparatus, comprising:
- a. A float actuated mechanical control valve wherein said float is supported by a liquid level that is in vapor and liquid communication with said level in said container;
- b. A heat recovery heat exchanger having hot and cold ends;
- c. A first conduit conveying liquid from said container to said hot end;
- d. A second conduit for conveying cooled container liquid from said cold end to said mechanical float-actuated control valve;
- and
- e. A third conduit for removal of cooled reduced pressure liquid from said valve
A heat recovery steam trap for a steam heated fluid heat exchanger, comprised of:
- a. A condensate level sensing steam trap, that prevents level buildup in said fluid heat exchanger;
- b. A condensate heat recovery heat exchanger;
- and
- c. A means for routing condensate from said fluid heat exchanger sequentially first to said condensate heat recovery heat exchanger, then to said steam trap.
An apparatus for removing condensate from a container, comprised of:
- a. An indirect acting level control valve for said container;
- b. A heat recovery heat exchanger in fluid communication with said container;
- and
- c. A conduit connecting said heat recovery heat exchanger to said indirect acting level control valve.
