Over the last few weeks we've examined the trap sizing out of a heat exchanger or coil with a modulating control valve. This week we turn our attention to the heat exchanger, or coil piping, after the steam trap. Often, the gravity condensate return main is installed overhead and there is a temptation to...
Read MoreIn this installment of our Steam Basics Series we will explore the steps for sizing the steam pipe and the pressure reducing valves using a health care office as an example. In this case, let's say the engineer is designing....
Read MoreWhen using a sizing program to select steam pipe sizes, the engineer or contractor is asked to fill in the capacity, the steam pressure, and the velocity required. The answer is ....
Read MoreA few weeks ago we discussed the steam pipe size entering a shell and tube heat exchanger, also called a convertor. This week we turn our attention to the condensate outlet. A customer recently asked, “I was told to pipe a 14-inch condensate drop leg from the bottom of a steam-to-water heat exchanger to the F&T trap inlet. What happens if I ...?”
Read MoreThis week we take a look at the vacuum breaker on a steam-to-water heat exchanger. Steam-to-water heat exchangers, or steam heating coils with on-off or modulating control valves, require a vacuum breaker. This simple and relatively inexpensive device may save ...
