Possible to vent mains too fast?
It's not possible to vent mains too fast on single pipe steam, is it? I know if you vent a radiator too fast, the vent closes before the radiator has had a chance to fill with steam in most of its sections. I can't imagine any harm in massive main venting, other than going broke with Big Mouth purchases. The reason I ask is that although I have already achieved 100% of my venting capacity on a branch main that offers just one 3/4 inch tapping, on which I have an antler with 3 Big Mouths (which slightly exceed the venting capacity of that 3/4 inch tapping), at the end of my primary main, where I already have an antler with Big Mouths, there is another tapping next to the antler, 1 inch, with a plug in it, and I could open that tapping and put in enough Big Mouths to max that 1 inch tapping (probably 4). No harm in massive main venting, other than financial pain from buying Big Mouths, right? Please advise.
One thing I should note is that my boiler is about 40% oversized. I cycle on pressure on some calls for heat, with my pressure limited to 1 pound cut out (I adjusted the calibration screw on my pressuretrol to allow it to cut out at 1 pound). I plan to add a Vaporstat this year or next year. You could argue that with even more massive venting on my mains, and my current 1 pound cut out and future plans to lower the cut out further, I would run an even shorter first cycle, since the boiler would not have to run as long while the air vents out of the mains. Any subsequent cycle following a first cycle on pressure would be shorter, too. I know that puts more wear and tear on the valve and the automatic damper and gives the flue and chimney less time to get really hot. But I'd be burning less gas, which is a good thing. Am I over-thinking this?
