It talks about why dry steam is more efficient, safer, and provide more consistent operation

Thanks Ray for the great lesson on the necessity of having dry steam in a steam system regardless of the steam's usage or the steam's pressure in the system and ways to keep the steam dry. Wet steam is always a big problem in every steam system.

Thanks Ray!

Below is a way you can tell how dry the steam is. I'm still waiting for that enterprising steam installer who wants to be able to prove that their piping is working as it should to utilize this inexpensive technology to differentiate their service.

I do have a question about your efficiency discussion. With the combustion efficiency we know that the waste goes up the chimney as heat.

But if there is inefficiency with wet steam, where does that waste heat energy go? I agree that wet steam is undesirable, but I'm not sure that inefficiency is a valid reason.

Thanks @retiredguy I appreciate the comment

@ethicalpaul I love you man LOL Thats awesome. Great question by the way. When there is water inside the steam system, it pulls the heat from the steam and the steam condenses.It starts a cascading effect as the more water or condensate that's in the pipe, the more the steam condenses, essentially short circuiting itself. The energy is transferred into the condensate. Now that starts problems of its own as the condensate temperature starts to increase. On a commercial system with a mechanical condensate pump, the hot condensate can flash to steam inside the pump volute, never a good idea. This destroys the impeller and since it's a gas now, the pump can't pump.

Have a great weekend
