What is Water Hammer - Boiling Point

[@jasonjohnsonHVAC]

Thats awesome....you can really see it on that inverted bucket trap.

excellent informative illustration...so says the Show Me State!

Thanks for the comment! Jude does a great job at explaining very complex concepts.

Really informative, great forces in the glass tube!

Thanks for watching!

Thanks for the great work! Can you tell me if a High-Pressure steam trap that is passing steam can cause water hammer in an HP condesate return line? Having a big problem in my plant with a water hammer in my HP condensate return line.

[@AdrianButler86]

I would say yes. Heres what i think can be happening. 1 if ur passin steam thru the trap it can be quickly condensing once it gets exposed to the cooler condensate and lower pressure area(cond return is open to atmosphere correct?) Which causing quick implosion as the steam shrinks 1600x its size as liquid condensate. That can def cause some hammering. That would be steam hammering id say. 2. The hi press steam passing thru the trap can be causing the condensate to flash quickly and now thats 1600x expansion of liq to steam which definitely causing hammering. 3. The fast flowing hi press steam passing over the top surface of liq cond on the bottom of the piping can grab slugs of water and launching them in the stream of moving steam and once theres a bend in piping(elbow) that water slams into the the fitting and that would cause water hammer.

In regards to hammering during blowdown like u spoke about at 4 min 7 secs..... Wouldnt the hammering during blowing down water from a feedwater controller or LWC off be more from the water in the boiler at a higher press than atmospheric instantly flashing to steam in the piping becuz when u crack the valve now u are introducing n exposing the hi press hi temp water to atmospheric press? And this would be steam hammer not water hammer. Isnt it that and not really that the line is not warmed up? I can understand hammering in a cold line if ur puttin steam into it cuz it will quickly condense and either the implosion of steam to liq causes the hammer and or the fact that it will draw slugs of water out the boiler quick and hammer soon as it hits an elbow or something. Please lemme know if i am gettin it right. Thanks

Hey Jude lemme run this by u and u can lemme know if i understand the video. So the clear piping u displayed with the water hammering is simply from the condensing of the steam introduced into the cooler and likely lower press area. The implosion due to the condensing of steam causes a vacuum effect which quickly pulls the water to replace the steam that once occupied the space before it condense. Tip for those who may not know why....... 1 lb of water in the form of steam occupies 1600x the space that the 1 lb of water occupies. So just imagine wat happens in reverse when u condense the steam. U know have ALOT of space that will be taken up by the water that is being sucked into that area.

Thanks for the comment!

Nothing like relieving an NON trained Newly licensed plant operator who has ignored His plant . Thus allowing a boiler to over fill forcing water into the steam header manifold . There's a big bang theory for You . Yup , sad reality I have seen several times.
