Steam take off three tees

edited November 2022 in THE MAIN WALL
What am I gaining or what’s physically happening, the unit I’m working on has minimum piping 1 riser then goes about 12 inches to the takeoff then another 6 inches to the equalizer then down to Hartford loop. It’s done correctly but out of the take off it has two tees and goes in three different directions, from reading here and looking at pics I know if I have to redo the pipes. I would put them all down to a manifold before going to the equalizer. Also two risers instead of one.. ( I’m not sure if I said that correctly)

    if what you said, is what I see in my mind, then yeah,
    2 boiler risers, 3 main take offs, then the equalizer drop,
    in that order

    I was really asking what’s the benefit of having three individuals take off instead of one take off and have it split to three different directions

    It's always better to have each main come to the header. But it depends on the connected EDR, and the size of the boiler. You need to check the sizing. If 1 riser is big enough so be it. It's not "automatic" that you always need more than one riser. And it's not "automatic" that the one take off is not large enough.

    You need to check the load and the output of the boiler. It's what the whole thing is all about.....steam velocity

    O k let me rephrase how do I or you sell a drop header & hypothetical say there was one riser , tell the customer I’m going to use both risers I am over size and give you 3 inch instead of 2 inch. I’m also going to split those two tees into 3 individual take off before going into the equalizer.
    The remark I get is well it worked before with the old boiler

    Makes it more tolerant of water quality issues in the boiler, makes the piping last longer if you never get wet steam. Helps with efficiency as well because it heats the fastest if the steam is always dry.

    In reality, if it is a budget job you would just use the sizes in the manual and make the risers as long as you have room for. if you don't have room for the minimum, that is when you must use a drop header. Otherwise a drop header is just extra insurance.
