Near-boiler piping questions (Photos included)

Heathapless

In reading through chapter four of Dan's book, I have a few questions about my system which dry-fired recently. I have included a few photos. Other photos are included under the heading "Causes of dry firing considered."



The install seems to be according to the manual for a W-M model LGB with the steam exiting through the boiler at the top rear side, carrying through a swing joint across the header and then dropping, The steam supply travels back horizontally before rising and then appears to be "bullheaded" through two welded pipes leaving in opposite directions, offset a bit. There is also another welded connection that leaves at this point and dead ends. The piping in much of the house is welded.



Is there anything in these photos that seems problematic?

Is the dead end absorbing velocity and hurting the movement of steam?

Is it possible that there used to be a vent at the end of the dead end?

How much of a disadvantage is bullheading and do the slightly offset exits help?



Could any of this be related to the dry firing?



To my eyes it seems like a competent job.





Thanks for your time and comments.

LGB ?

Is your boiler an LGB 4 to LGB 12 ?

Or is it an LGB 13 to LGB 23 ?

Depending on what model it is that depends on how it is supposed to be piped.  You likely have it all-ready, but here is the manual.  Review page 18, determine which model you have, then measure the currently installed piping, then compare that to page 18.  http://www.weil-mclain.com/en/multimedia-library/pdf/weil-mclain-pdf/products/boilers/commercial-boilers/lgb/lgb_boiler_manual.pdf
