Method and device for thermally controlling a utilization unit fed by a condensable vapor distributing system

A method for thermally controlling a utilization apparatus heated with condensable steam, mounted in a live steam distribution plant comprising a condensate drain line system for dry gravity return of the condensates which also contains live steam, said method consisting in a selectively variable storage of the condensates through modulated retention within said utilization apparatus, wherein the improvement comprises the step of selectively heating said cooled condensates coming from each aforesaid utilization apparatus with adjustable operating heat output characteristics and keeping them at a temperature approaching that of said live steam before conveying them to said condensate drain line system.

A device for thermally controlling a utilization apparatus heated with condensable steam with adjustable operating heat output characteristics mounted in a live steam distribution plant including a condensate drain line system for dry gravity return of the condensates which also contains live steam, said apparatus being connected through at least one outgoing condensate drain duct to said steam distributing plant, wherein the improvement comprises means for reheating said condensates and contacting said condensates only after reheating with the steam.

A method for thermally controlling a utilization apparatus having an inlet for steam and an outlet for condensates heated with condensable steam, mounted in a live steam distribution plant comprising a condensate drain line system for dry gravity return of the condensates which also contains live steam, said method consisting in a selectively variable storage of the condensates through modulated retention within said utilization apparatus, wherein the improvement comprises the step of using as a heating medium live steam taken from said steam distributing plant to reheat the condensates prior to the return of the condensates to the inlet of the utilization apparatus.

A device for thermally controlling a utilization apparatus heated with condensable steam with adjustable operating heat output characteristics mounted in a live steam distribution plant including a condensate drain line system for dry gravity return of the condensates which also contains live steam, said apparatus being connected through at least one outgoing condensate drain duct to said steam distributing plant, wherein the improvement comprises at least one condensate outlet connected to one outgoing condensate drain duct containing a flow rate control member, said device comprising a heater unit with very quick or gradual action interposed in series in said outgoing condensate drain duct between said utilization apparatus and said control member.
