Last week we answered the question, “What size should the steam pipe be after the control valve entering the heat exchanger”. The responses I received were positive and a few of you introduced this week’s question. Solution: We continue to review the steam and condensate piping around a steam to water heat exchanger used for plumbing and hydronic heating applications. We will look at one area of the above schematic each week in roughly the following order: A: Why are most steam to water heat exchangers in building services provided with low pressure steam rather than medium or high pressure? B: Why do I need a vacuum breaker and where should it be located? C: Why is the rule of thumb 14" for the drop leg to the steam trap and what happens if it is more or less than 14"? D: Is there a difference between steam strainers and condensate strainers? E: Types of traps and sizing of traps. F: Lift vs. gravity returns out of heat exchangers used for domestic water and hydronic heating. G: Flash steam and flash tanks. H: Condensate pipe sizing and flash steam. I: Temperature of condensate and condensate return units. J: Condensate pump discharge piping. K: Saving energy with vent condensers. L: Shell and tube vs. plate exchangers in steam applications.
