Near Boiler Piping for Steam (16 Series Utica Boiler - UH1605HSID)

Does anyone know what are the pipes that are going down here ?
Are they cutting through some floor?
Or are they just dead end for debris collection ?

This image is from their instruction booklet - I have marked the mystery piping with arrows.

    A drip leg, dirt leg....just a pipe nipple with a cap on the end.
    They will fill with sludge and sediment and should be opened and checked every year or so.

    The nipple is often cut to length so the cap sits on the floor providing support.
    But then those are a bear to remove.
    You can put a brick below them to sit on and by removing the brick you could unscrew the dirt leg.
