If I wanted to how would I remove a plug from a 2 1/2 tapping on a steam boiler. It looks like it would require a square drive like for a socket wrench only much bigger. Is there a special tool to do this with?
I am thinking about redoing the near boiler piping to my boiler next summer. It is a 1979 120,000 BTU Dunkirk. It is working quite well after I replaced all the return piping, installed an electronic LWCO, automatic water feeder, reduced the pressure to 2 psig, and gave it a thorough cleaning. However, in my continuing research I think it was installed incorrectly in the first place resulting in too high steam velocity exiting the boiler (calculated to be around 30 fps). Possibly I will add a second riser or change the the existing riser to one that matches the size of the boiler tapping. (2" vs. 2 1/2"). Any thoughts?
